PBR is a state-of-the-art rendering technique used in modern graphics applications and game engines. This repository contains a minimalistic implementation that showcases both diffuse lighting and image-based lighting techniques.
- Diffuse Lighting: Achieve a realistic representation of light interaction with surfaces.
- Specular Lighting & Split-sum Approximation: Advanced techniques to capture intricate light reflections.
- OpenGL Renderer: Leverage the power of GPU to render complex scenes in real-time.
- Modular Architecture: Separate components for easy extension and experimentation.
- OpenGL
- GLFW3
- ASSIMP
🚀 Note: Make sure to place the downloaded assets in the appropriate directories before running the project.
- Clone this repository:
git clone https://github.com/PixelSenseiAvi/LightingInPBR.git - Navigate to the project directory:
cd PBR - Create a build directory and navigate to it:
mkdir build && cd build - Generate the project files:
cmake .. - Build the project:
cmake --build . --config Release
Once compiled, you can run the executable PBR from the build directory.
