Coffee_Smoke.mp4
🪄 Imagine a cozy scene with a steaming cup of coffee, where gentle smoke rises and swirls in the air.
This project lets you bring that serene moment to life with captivating smoke animations using vertex and fragment shaders by leveraging Perlin texture for improved performance.
Whether you're a shader enthusiast or a curious beginner, this project offers a fun and rewarding way to boost your skills. 🏅
Imagine this:
- You want to animate smoke rising from a coffee mug. It sounds simple, but it's a fantastic way to practice your shader skills! The table and mug are already modeled in Blender, so you're all set to focus on the smoke effect. 🗯️
🛠️ To keep things smooth and efficient, especially for web performance, we employ custom shaders and Perlin texture to achieve a realistic smoke appearance while maintaining performance efficiency.
The key steps include generating a Perlin noise texture, applying it to a particle system, and simulating the movement and diffusion of smoke particles.
This technique is a favorite in video games to ensure optimal performance.
When choosing a noise texture, remember these three essential tips:
-
Enough Variations:
Ensure your texture has ample variations to avoid repetitive patterns and keep the smoke looking realistic. -
Big Enough (at least 128x128):
Larger textures provide more detail, resulting in a smoother and more natural smoke effect. -
Seamless Tiling:
Your texture should tile seamlessly to avoid visible edges and ensure a continuous smoke flow.
Film and Animation:
Enhancing visual storytelling by adding realistic smoke effects to scenes involving hot beverages or smoky environments.Video Games:
Creating immersive environments by simulating smoke from various sources such as mugs, chimneys, or campfires.Virtual Reality (VR) and Augmented Reality (AR):
Improving realism in virtual environments by integrating dynamic smoke effects.Advertising and Marketing:
Developing eye-catching visuals for commercials or product presentations involving hot drinks.Web Development:
Adding engaging visual effects to websites, especially for interactive storytelling or product showcases.
By understanding and implementing this project, developers and artists can apply similar techniques to other particle-based effects, such as fog, fire, or magical particles.
The project involves the following components:
- Three.js: A JavaScript library used to create and display animated 3D computer graphics in a web browser.
- Custom Shaders: Shaders written in GLSL (OpenGL Shading Language) to control the rendering of smoke particles.
- Perlin Texture: A precomputed Perlin noise texture used for simulating the smoke effect efficiently, avoiding the performance overhead of calculating Perlin noise in real-time.
- Particle System: Generating particles at the mug's surface to represent smoke particles.
- Smoke Simulation: Applying transformations and movements to simulate the rising and dispersing behavior of smoke.
- Performance Optimization: Using Perlin texture to enhance performance by precomputing noise patterns.
- Programming Language: JavaScript
- Graphics Library: Three.js
- Shader Language: GLSL
The techniques used in this project are applicable to various other visual effects and simulations, such as:
Fog and Mist:
Simulating atmospheric effects for outdoor scenes in games or movies.Fire and Explosions:
Using particle systems and noise textures to create dynamic fire or explosion effects.Magical Effects:
Creating particle-based effects for magical spells or fantasy elements in games and animations.Water and Liquid Simulations:
Simulating splashes, waves, or other fluid behaviors using similar particle system techniques.
By adapting the principles of custom shaders and Perlin textures, we can create a wide range of visual effects with efficient performance.
