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!
