This project had several important aspects;
- Learning GLSL
- Understanding the ECS game architecture
- Deepening my knowledge of physics
The goal was to implement a rendering pipeline (using OpenGL), a linear algebra library (specifically for vector and matrix operations), a generalized (though not portable) device input package and a physics simulation.
Features:
- Linear algebra library for vector-vector and matrix-vector operations etc.
- File packing and unpacking
- 3DS file loader (standardized CAD/3D model format)
- Rigid body physics (using fourth-order Runge—Kutta integration)
- GLSL shaders (compiled and run on the GPU)
- Material shader (Phong shading model)
- Noise/fake-ISO shader
- Motion blur shader (Custom implementation)
- Exposure shader (Solvent based)
- ECS architecture
Everything was implemented in C, although I did not follow the C89 standard, but rather C99 and even some C11 features (by extension since the MSVC++ compiler is not quite there yet).
Notice the use of ADS (ambient-diffuse-specular) material shaders, a (barely noticeable) noise shader, a motion blur shader as well as an exposure shader for mor realistic colors!
