The first one was made by Van Gogh's hand applying layer over layer of paint. It took him hours. The second was produced in seconds by the combination of four matrices of pixels: one for cyan, one for magenta, one for yellow and one for black. The key difference is that the second image is produced in a non-serial way (that means not step-by-step, but all at the same time). + +This book is about the revolutionary computational technique, *fragment shaders*, that is taking digitally generated images to the next level.

This is why they're used in all sort of cases, from video filters on cellphones to incredible 3D video games. + +![Journey by The Game Company](journey.jpg) + +In the following chapters you will discover how incredibly fast and powerful this technique is and how to apply it to your professional and personal work. + +## Who is this book for? + +This book is written for creative coders, game developers and engineers who have coding experience, a basic knowledge of linear algebra and trigonometry, and who want to take their work to an exciting new level of graphical quality. (If you want to learn how to code, I highly recommend you start with [Processing](https://processing.org/) and come back later when you are comfortable with it.) + +This book will teach you how to use and integrate shaders into your projects, improving their performance and graphical quality. Because GLSL (OpenGL Shading Language) shaders compile and run on a variety of platforms, you will be able to apply what you learn here to any enviroment that uses OpenGL, OpenGL ES or WebGL. In other words, you will be able to apply and use your knowledge with [Processing](https://processing.org/) sketches, [openFrameworsk](http://openframeworks.cc/) applications, [Cinder](http://libcinder.org/) interactive installations, [Three.js](http://threejs.org/) websites or iOS/Android games. + +## What does this book cover? + +This book will focus on the use of GLSL pixel shaders. First we'll define what shaders are; then we'll learn how to make procedural shapes, patterns, textures and animations with them. You'll learn the foundations of shading language and apply it to more useful scenarios such as: image processing (image operations, matrix convolutions, blurs, color filters, lookup tables and other effects) and simulations (Conway's game of life, Gray-Scott's reaction-diffusion, water ripples, watercolor effects, Voronoi cells, etc.). Towards the end of the book we'll see a set of advanced techniques based on Ray Marching. + +*There are interactive examples for you to play with in every chapter.* When you change the code, you will see the changes immediately.

Some tasks are bigger than others, which means they require more time and energy to deal with. We say they require more processing power. Because of the architecture of computers the jobs are forced to run in a series; each job has to be finished one at a time. Modern computers usually have groups of four processors that work like these pipes, completing tasks one after another to keeping things running smoothly. Each pipe is also known as *thread*. + +![CPU](00.jpeg) + +Video games and other graphic applications require a lot more processing power than other programs. Because of their graphic content they have to do huge numbers of pixel-by-pixel operations. Every single pixel on the screen needs to be computed, and in 3D games geometries and perspectives need to be calculated as well. + +Let's go back to our metaphor of the pipes and tasks. Each pixel on the screen represents a simple small task. Individually each pixel task isn't an issue for the CPU, but (and here is the problem) the tiny task has to be done to each pixel on the screen! That means in an old 800x600 screen, 480,000 pixels have to processed per frame which means 14,400,000 calculations per second! Yes! That’s a problem big enough to overload a microprocessor. In a modern 2880x1800 retina display running at 60 frames per second that calculation adds up to 311,040,000 calculations per second. How do graphics engineers solve this problem? + +![](03.jpeg) + +This is when parallel processing becomes a good solution. Instead of having a couple of big and powerful microprocessors, or *pipes*, it is smarter to have lots of tiny microprocessors running in parallel at the same time.

But a table of 800x600 tiny pipes receiving 30 waves of 480,000 pixels a second can be handled smoothly. This works the same at higher resolutions - the more parallel hardware you have, the bigger the stream it can manage. + +Another “super power” of the GPU is special math functions accelerated via hardware, so complicated math operations are resolved directly by the microchips instead of by software. That means extra fast trigonometrical and matrix operations - as fast as electricity can go. + +## What is GLSL? + +GLSL stands for openGL Shading Language, which is the specific standard of shader programs you'll see in the following chapters. There are other types of shaders depending on hardware and Operating Systems. Here we will work with the openGL specs regulated by [Khronos Group](https://www.khronos.org/opengl/). Understanding the history of OpenGL can be helpful for understanding most of its weird conventions, for that I recommend taking a look at: [openglbook.com/chapter-0-preface-what-is-opengl.html](http://openglbook.com/chapter-0-preface-what-is-opengl.html) + +## Why are Shaders famously painful? + +As Uncle Ben said “with great power comes great responsibility,” and parallel computation follows this rule; the powerful architectural design of the GPU comes with its own constrains and restrictions. + +In order to run in parallel every pipe, or thread, has to be independent from every other thread. We say the threads are *blind* to what the rest of the threads are doing. This restriction implies that all data must flow in the same direction. So it’s impossible to check the result of another thread, modify the input data, or pass the outcome of a thread into another thread. Allowing thread-to-thread communications puts the integrity of the data at risk. + +Also the GPU keeps the parallel micro-processor (the pipes) constantly busy; as soon as they get free they receive new information to processes. It's impossible for a thread to know what it was doing in the previous moment. It could be drawing a button from the UI of the operating system, then rendering a portion of sky in a game, then displaying the text of an email. Each thread is not just **blind** but also **memoryless**. Besides the abstraction require to code a general function that changes the result pixel by pixel depending on its position, the blind and memoryless constraints make shaders not very popular among beginning programmers. + +Don't worry! In the following chapters, we will learn step-by-step how to go from simple to advanced shading computations.

+ +If you are reading this book in a browser the previous block of code is interactive. That means you can click and change any part of the code you want to explore. Changes will be updated immediately thanks to the GPU architecture that compiles and replaces shaders *on the fly*. Give it a try by changing the values on line 6. + +Although these simple lines of code don't look like a lot, we can infer substantial knowledge from them: + +1. Shader Language has a single ```main``` function that returns a color at the end. This is similar to C. + +2. The final pixel color is assigned to the reserve global variable ```gl_FragColor```. + +3. This C-flavored language has built in *variables* (like ```gl_FragColor```), *functions* and *types*. In this case we've just been introduced to ```vec4``` that stands for a four dimensional vector of floating point precision. Later we will see more types like ```vec3``` and ```vec2``` together with the popular: ```float```, ```int``` and ```bool```. + +4. If we look closely to the ```vec4``` type we can infer that the four arguments respond to the RED, GREEN, BLUE and ALPHA channels. Also we can see that these values are *normalized*, which means they go from ```0.0``` to ```1.0```. Later, we will learn how normalizing values makes it easier to *map* values between variables. + +5. Another important *C feature* we can see in this example is the presence of preprocessor macros. Macros are part of a pre-compilation step. With them it is possible to ```#define``` global variables and do some basic conditional operation ( with ```#ifdef``` and ```#endif```). All the macro comands begin with a hastag (```#```). Pre-compilation happens right before compiling and copies all the calls to ```#defines``` and check ```#ifdef``` (is defined) and ```#ifndef``` (is not defined) conditionals. In our "hello world!" example above, we only insert the line 2 if ```GL_ES``` is defined, which mostly happens when the code is compiled on mobile devices and browsers. + +6. Float types are vital in shaders, so the level of *precision* is crucial. Lower precision means faster rendering, but on behalf of quality. You can be picky and specify the precision of each variable that uses floating point. In the first line (```precision mediump float;```) we are setting all floats to medium precision. But we can choose to set them to low (```precision lowp float;```) or high (```precision highp float;```). + +7. The last, and maybe most important, detail is that GLSL specs don’t guarantee that variables will be automatically casted. What does that mean? Manufacturers have different approaches to accelerate graphic card processes but they are forced to guarantee minimum specs. Automatic casting is not one of them. In our “hello world!” example ```vec4``` has floating point precision and for that it expects to be assigned with ```floats```. If you want to make good consistent code and not spend hours debugging white screens, get used to putting the point ( ```.``` ) in your floats. This kind of code will not always work: + +```glsl +void main() { + gl_FragColor = vec4(1,0,0,1); // ERROR +} +``` + +Now that we've described the most relevant elements of our "hello world!" program, it's time to click on the code block and start challenging all that we've learned. You will note that on errors, the program will fail to compile, showing a white screen. There are some interesting things to try, for example: + +* Try replacing the floats with integers, your graphic card may or may not tolerate this behavior. + +* Try commenting out line 6 and not assigning any pixel value to the function. + +* Try making a separate function that returns a specific color and use it inside ```main()```. As a hint, here is the code for a function that returns a red color: + +```glsl +vec4 red(){ + return vec4(1.0,0.0,0.0,1.0); +} +``` + +* There are multiple ways of constructing ```vec4``` types, try to discover other ways. The following is one of them: + +```glsl +vec4 color = vec4(vec3(1.0,0.0,1.0),1.0); +``` + +Although this example isn't very exciting, it is the most basic example - we are changing all the pixels inside the canvas to the same exact color. In the following chapter we will see how to change the pixel colors by using two types of input: space (the place of the pixel on the screen) and time (the number of seconds since the page was loaded). diff --git a/02/hello_world.frag b/02/hello_world.frag new file mode 100644 index 00000000..4748df13 --- /dev/null +++ b/02/hello_world.frag @@ -0,0 +1,11 @@ +#ifdef GL_ES +precision mediump float; +#endif + +void main() { + gl_FragColor = vec4(1.0,0.0,1.0,1.0); +} + + + + diff --git a/02/index.html b/02/index.html new file mode 100644 index 00000000..e95b730f --- /dev/null +++ b/02/index.html @@ -0,0 +1,69 @@ + + + + + + + Hello World + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + +

Although each parallel thread is blind to the others, we need to be able to send some inputs from the CPU to all the threads. Because of the architecture of the graphic card those inputs are going to be equal (*uniform*) to all the threads and necessarily set as *read only*. In other words, each thread receives the same data which it can read but cannot change. + +These inputs are call ```uniform``` and come in most of the supported types: ```float```, ```vec2```, ```vec3```, ```vec4```, ```mat2```, ```mat3```, ```mat4```, ```sampler2D``` and ```samplerCube```.

The names will vary from implementation to implementation but in this series of examples I’m always passing: ```u_time``` (time in seconds since the shader started), ```u_resolution``` (billboard size where the shader is being drawn) and ```u_mouse``` (mouse position inside the billboard in pixels). I’m following the convention of putting ```u_``` before the uniform name to be explicit about the nature of this variable but you will find all kinds of names for uniforms. For example [ShaderToy.com](https://www.shadertoy.com/) uses the same uniforms but with the following names: + +```glsl +uniform vec3 iResolution; // viewport resolution (in pixels) +uniform vec4 iMouse; // mouse pixel coords. xy: current, zw: click +uniform float iGlobalTime; // shader playback time (in seconds) +``` + +Enough talking, let's see the uniforms in action. In the following code we use ```u_time``` - the number of seconds since the shader started running - together with a sine function to animate the transition of the amount of red in the billboard. + +
+ +As you can see GLSL has more surprises. The GPU has hardware accelerated angle, trigonometric and exponential functions. Some of those functions are: [```sin()```](http://www.shaderific.com/glsl-functions/#sine), [```cos()```](http://www.shaderific.com/glsl-functions/#cosine), [```tan()```](http://www.shaderific.com/glsl-functions/#tangent), [```asin()```](http://www.shaderific.com/glsl-functions/#arcsine), [```acos()```](http://www.shaderific.com/glsl-functions/#arccosine), [```atan()```](http://www.shaderific.com/glsl-functions/#arctangent), [```pow()```](http://www.shaderific.com/glsl-functions/#exponentiation), [```exp()```](http://www.shaderific.com/glsl-functions/#exponentiation), [```log()```](http://www.shaderific.com/glsl-functions/#naturallogarithm), [```sqrt()```](http://www.shaderific.com/glsl-functions/#squareroot), [```abs()```](http://www.shaderific.com/glsl-functions/#absolutevalue), [```sign()```](http://www.shaderific.com/glsl-functions/#sign), [```floor()```](http://www.shaderific.com/glsl-functions/#floor), [```ceil()```](http://www.shaderific.com/glsl-functions/#ceiling), [```fract()```](http://www.shaderific.com/glsl-functions/#fractionalpart), [```mod()```](http://www.shaderific.com/glsl-functions/#modulo), [```min()```](http://www.shaderific.com/glsl-functions/#minimum), [```max()```](http://www.shaderific.com/glsl-functions/#maximum) and [```clamp()```](http://www.shaderific.com/glsl-functions/#clamp). + +Now is time again to play with the above code. + +* Slow down the frequency until the color change becomes almost imperceptible. + +* Speed it up until you see a single color without flickering. + +* Play with the three channels (RGB) in different frequencies to get interesting patterns and behaviors. + +## gl_FragCoord + +In the same way GLSL gives us a default output, ```vec4 gl_FragColor```, it also gives us a default input, ```vec4 gl_FragCoord```, which holds the screen coordinates of the *pixel* or *screen fragment* that the active thread is working on. With ```vec4 gl_FragCoord```, we know where a thread is working inside the billboard. In this case we don't call it ```uniform``` because it will be different from thread to thread, instead ```gl_FragCoord``` is called a *varying*. + +
+ +In the above code we *normalize* the coordinate of the fragment by dividing it by the total resolution of the billboard. By doing this the values will go between ```0.0``` and ```1.0```, which makes it easy to map the X and Y values to the RED and GREEN channel. + +In shader-land we don’t have too many resources for debugging besides assigning strong colors to variables and trying to make sense of them. You will discover that sometimes coding in GLSL is very similar to putting ships inside bottles. Is equally hard, beautiful and gratifying. + +![](08.png) + +Now it is time to try and challenge our understanding of this code. + +* Can you tell where the coordinate ```(0.0,0.0)``` is in our canvas? + +* What about ```(1.0,0.0)```, ```(0.0,1.0)```, ```(0.5,0.5)``` and ```(1.0,1.0)```? + +* Can you figure out how to use ```u_mouse``` knowing that the values are in pixels and NOT normalized values? Can you use it to move colors around? + +* Can you imagine an interesting way of changing this color pattern using ```u_time``` and ```u_mouse``` coordinates? + +After doing these exercises you might wonder where else you can try your new shader-powers. In the following chapter we will see how to make your own shader tools in three.js, Processing, and openFrameworks. \ No newline at end of file diff --git a/03/index.html b/03/index.html new file mode 100644 index 00000000..2681e7a2 --- /dev/null +++ b/03/index.html @@ -0,0 +1,70 @@ + + + + + + + Uniforms + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + +

The following are examples of how to set shaders in some popular frameworks with the same uniforms that we are going to use throughout this book. (In the [GitHub repository for this chapter](https://github.com/patriciogonzalezvivo/GLSL-Book/tree/master/04), you'll find the full source code for these three frameworks.) + +**Note**: In case you don't want to try shaders on the following frameworks, but you want to work outside a browser, you can download and compile [glslViewer](https://github.com/patriciogonzalezvivo/glslViewer). This MacOS and RaspberryPi program runs directly from terminal and is especially designed to execute the examples in this book. + +### In **Three.js** + +The brilliant and very humble Ricardo Cabello (aka [MrDoob](https://twitter.com/mrdoob) ) has been developing along with other [contributors](https://github.com/mrdoob/three.js/graphs/contributors) probably one of the most famous frameworks for WebGL, called [Three.js](http://threejs.org/). You will find a lot of examples, tutorials and books that teach you how to use this JavaScript library to make cool 3D graphics. + +Below is an example of the HTML and JS you need to get started with shaders in three.js. Pay attention to the ```id="fragmentShader"``` script, here is where you can copy the shaders you find in this book. + +```html + +
+ + + + + +``` + +### In **Processing** + +Started by [Ben Fry](http://benfry.com/) and [Casey Reas](http://reas.com/) in 2001, [Processing](https://processing.org/) is an extraordinarily simple and powerful environment in which to take your first steps in code (it was for me at least). [Andres Colubri](https://codeanticode.wordpress.com/) has made important updates to the openGL and video in Processing, making it easier than ever to use and play with GLSL shaders in this friendly environment. Processing will search for the shader named ```"shader.frag"``` in the ```data``` folder of the sketch. Be sure to copy the examples you find here into that folder and rename the file. + +```processing +PShader shader; + +void setup() { + size(640, 360, P2D); + noStroke(); + + shader = loadShader("shader.frag"); +} + +void draw() { + shader.set("u_resolution", float(width), float(height)); + shader.set("u_mouse", float(mouseX), float(mouseY)); + shader.set("u_time", millis() / 1000.0); + shader(shader); + rect(0,0,width,height); +} +``` + +In the order for the shader to work, you need to add the following line at the beginning of your shader: ```#define PROCESSING_COLOR_SHADER```. So in Processing a shader looks like this: +```glsl +#ifdef GL_ES +precision mediump float; +#endif + +#define PROCESSING_COLOR_SHADER + +uniform vec2 u_resolution; +uniform vec3 u_mouse; +uniform float u_time; + +void main() { + vec2 st = gl_FragCoord.st/u_resolution; + gl_FragColor = vec4(st.x,st.y,0.0,1.0); +} +``` + +For more information about shaders in Processing check out this [tutorial](https://processing.org/tutorials/pshader/). + +### In **openFrameworks** + +Everybody has a place where they feel comfortable, in my case, that’s still the [openFrameworks community](http://openframeworks.cc/). This C++ framework wraps around OpenGL and other open source C++ libraries. In many ways it's very similar to Processing, but with the obvious complications of dealing with C++ compilers. In the same way as Processing, openFrameworks will search for your shaders files in the data folder, so don’t forget to copy the ```.frag``` files you want to use and change the name when you load them. + +```cpp +void ofApp::draw(){ + ofShader shader; + shader.load("","shader.frag"); + + shader.begin(); + shader.setUniform1f("u_time", ofGetElapsedTimef()); + shader.setUniform2f("u_resolution", ofGetWidth(), ofGetHeight()); + ofRect(0,0,ofGetWidth(), ofGetHeight()); + shader.end(); +} +``` + +For more information about shaders in openFrameworks go to this [excellent tutorial](http://openframeworks.cc/tutorials/graphics/shaders.html) made by [Joshua Noble](http://thefactoryfactory.com/). diff --git a/04/index.html b/04/index.html new file mode 100644 index 00000000..2981cee4 --- /dev/null +++ b/04/index.html @@ -0,0 +1,69 @@ + + + + + + Make your own shader tool + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + +

Previously, we mapped the normalized position on *x* and *y* to the *red* and *green* channels. Essentially we made a function that takes a two dimensional vector (x and y) and returns a four dimensional vector (r, g, b and a). But before we go further transforming data between dimensions we need to start simpler... much simpler. That means understanding how to make one dimensional functions. The more energy and time you spend learning and mastering this, the stronger your shader karate will be. + +![The Karate Kid (1984)](mr_miyagi.jpg) + +The following code structure is going to be our fence. In it, we visualize the normalized value of the *x* coordinate (```st.x```) in two ways: one with brightness (observe the nice gradient from black to white) and the other by plotting a green line on top (in that case the *x* value is assigned directly to *y*). + +
+ +**Quick Note**: The ```vec3``` type constructor "understands" that you want to assign the three color channels with the same value, while ```vec4``` understands that you want to construct a four dimensional vector with a three dimensional one plus a fourth value (in this case the value that controls the alpha or opacity). See for example lines 20 and 26 above. + +This code is your fence; it's important to observe and understand it. You will come back over and over to this space between *0.0* and *1.0*. You will master the art of blending and shaping this line. + +This one-to-one relationship between *x* and *y* (or the brightness) is know as *linear interpolation*. From here we can use some mathematical functions to *shape* the line. For example we can raise *x* to the power of 5 to make a *curved* line. + +
+ +Interesting, right? On line 19 try different exponents: 20.0, 2.0, 1.0, 0.0, 0.2 and 0.02 for example. Understanding this relationship between the value and the exponent will be very helpful. Using these types of mathematical functions here and there will give you expressive control over your code, a sort of data acupuncture that let you control the flow of values. + +```pow``` is a native function in GLSL, and there are many others. Most of them are accelerated at the level of the hardware, which means if they are used in the right way and with discretion they will make your code faster. + +Replace the power function on line 19. Try other ones like: [```exp()```](http://www.shaderific.com/glsl-functions/#exponentiation), [```log()```](http://www.shaderific.com/glsl-functions/#naturallogarithm) and [```sqrt()```](http://www.shaderific.com/glsl-functions/#squareroot). Some of these functions are more interesting when you play with them using PI. For that you can see that in line 5 I have defined a macro that will replace any call to ```PI``` with the value ```3.14159265359```. + +### Step and Smoothstep + +GLSL also has some unique native interpolation functions that are hardware accelerated. + +The ```step``` interpolation receives two parameters. The first one is the limit or threshold, while the second one is the value we want to check or pass. Any value under the limit will return ```0.0``` while everything above the limit will return ```1.0```. + +Try changing this threshold value on line 20 of the following code. + +
+ +The other unique function is known as ```smoothstep```. Given a range of two numbers and a value, this function will interpolate the value between the defined range. The two first parameters are for the beginning and end of the transition, while the third is for the value to interpolate. + +
+ +In the previous example, on line 12, notice that we’ve been using smoothstep to draw the green line on the ```plot()``` function. For each position along the *x* axis this function makes a *bump* at a particular value of *y*. How? By connecting two ```smoothstep()``` together. Take a look at the following function, replace it for line 20 above and think of it as a vertical cut. The background does look like a line, right? + +```glsl + float y = smoothstep(0.2,0.5,st.x) - smoothstep(0.5,0.8,st.x); +``` + +### Sine and Cosine + +When you want to use some math to animate, shape or blend values, there is nothing better than being friends with sine and cosine. + +These two basic trigonometric functions that work together to construct circles are as handy as MacGyver’s Swiss army knife. It’s important to know how they behave and in what ways they can be combined. In a nutshell, given an angle (in radians) they will return the correct position of *x* (cosine) and *y* (sine) of a point on the edge of a circle with a radius equal to 1. But, the fact that they return normalized values (values between -1 and 1) in such a smooth way makes them an incredible tool. + +![](sincos.gif) + +While it's difficult to describe all the relationships between trigonometric functions and circles, the above animation does a beautiful job of visually summarizing these relationships. + +
+ +Take a careful look at this sine wave. Note how the *y* values flow smoothly between +1 and -1. As we saw in the time example in the previous chapter, you can use this rhythmic behavior of ```sin``` to animate properties. If you are reading this example in a browser you will see that the you can change the code in the formula above to watch how the wave changes. (Note: don't forget the semicolon at the end of the lines.) + +Try the following exercises and notice what happens: + +* Add time (```u_time```) to *x* before computing the ```sin```. Internalize that **motion** along *x*. + +* Multiply *x* by ```PI``` before computing the ```sin```. Note how the two phases **shrink** so each cycle repeats every 2 integers. + +* Multply time (```u_time```) by *x* before computing the ```sin```. See how the **frequency** between phases becomes more and more compressed. + +* Add 1.0 to ```sin(x)```. See how all the wave is **displaced** up and now all values are between 0.0 and 2.0. + +* Multiply ```sin(x)``` by 2.0. See how the **amplitude** doubles in size. + +* Compute the absolute value (```abs()```) of ```sin(x)```. It looks like the trace of a **bouncing** ball. + +* Extract just the fraction part (```fract()```) of the resultant of ```sin(x)```. + +* Add the higher integer (```ceil()```) and the smaller integer (```floor()```) of the resultant of ```sin(x)``` to get a digital wave of 1 and -1 values. + +### Some extra useful functions + +At the end of the last exercise we introduced some new functions. Now it’s time to experiment with each one by uncommenting the lines below one at a time. Get to know these functions and study how they behave. I know, you are wondering... why? A quick google search on "generative art" will tell you. Keep in mind that these functions are our fence. We are mastering the movement in one dimension, up and down. Soon, it will be time for two, three and four dimensions! + +![Anthony Mattox (2009)](anthony-mattox-ribbon.jpg) + +

A few years ago, taking for granted that all the students would have a computer with a modern graphic card was a long shot, but not today. Thanks to the [RaspberryPi project](http://www.raspberrypi.org/) a new type of small and cheap generation of computers ($35) has found its way into classrooms. Most importantly for the purposes of this book, the [RaspberryPi](http://www.raspberrypi.org/) comes with a decent Bradcom GPU card that can be accessed directly from the console. I made a [flexible GLSL live coding tool](https://github.com/patriciogonzalezvivo/glslViewer) that runs all the examples in this book while also updating automatically the changes the user makes when they save it. By making a local copy of the repository of this book (see the above section) and having the [```glslViewer``` app installed](https://github.com/patriciogonzalezvivo/glslViewer), students can read the chapters using any console text reader (like ```less```, ```nano``` or ```vim```), run the examples (with ```glslviewer```), and modify them with their favorite text editor (like ```nano```, ```pico```, ```vi```, ```vim``` or ```emacs```). + +To install and set this all up on the RaspberryPi after installing the OS and logging in, type the following commands: + +```bash +sudo apt-get update +sudo apt-get upgrade +sudo apt-get install git-core libfreeimage +cd ~ +git clone http://github.com/patriciogonzalezvivo/glslViewer.git +cd glslViewer +make +make install +cd ~ +git clone https://github.com/patriciogonzalezvivo/thebookofshaders.git +cd GLSL-Book +``` + +At the end of each section you will find code and non-code based exercises to give to your students. They are designed to help students immediately put concepts into practice, making concrete the abstract principles of parallel programming. + diff --git a/91/index.html b/91/index.html new file mode 100644 index 00000000..a04e83af --- /dev/null +++ b/91/index.html @@ -0,0 +1,68 @@ + + + + + + + Using this book with a RasbperryPi + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + +
