A software (CPU) and hardware (GPU) rasterizer built with C++ and DirectX 11. You can switch between both rasterizers at runtime and change various render settings on the fly.
- Full rasterization pipeline on the CPU (vertex transformation, triangle rasterization, depth testing, pixel shading)
- Lambert diffuse + Phong specular shading (BRDF)
- Normal mapping
- Multiple shading/debug modes: observed area, diffuse only, specular only, combined
- Depth buffer visualization
- Bounding box visualization
- DirectX 11 rendering pipeline
- HLSL pixel shading (same lighting model as software)
- Texture sampling modes: point, linear, anisotropic
- Toggle between software and hardware rasterizer (F1)
- Cull mode cycling: back, front, none
- Camera with mouse look and keyboard movement
- OBJ mesh loading with diffuse, normal, specular and glossiness textures
- Custom math library (vectors, matrices)
- Fire mesh with partial coverage (alpha blending)
