Software Ray Tracer / Rasterizer

CPU ray-tracer + rasterizer entirely done in C++ and Qt6 for the interface.

Features

Qt6 C++ Interface

C++ QT6 Interface

Ray tracing rendering
Rasterization rendering
Hybrid rendering (rasterization of the visibility + ray tracing for the shading)
Clip-space clipping algorithm
Hard shadows (shadow rays)

Ray-traced hard shadows

Octree based BVH + 7 planes bounding volumes
Rough reflexions (random ray cast around the normal)
Normal mapping
Diffuse texture, roughness map, ambient occlusion mapping
Parallax occlusion mapping
Skyspheres support

Showcase of implemented normal mapping, parallax occlusion mapping, rough reflexions & skysphere support. The mesh of the sphere is perfectly flat (analytic sphere). The perceived geometry is only due to the parallax mapping algorithm.

Skyboxes support
Super Sampling Anti Aliasing (SSAA)
AVX2 Screen Space Ambient Occlusion (SSAO) implementation

Showcase of the SIMD AVX2 Screen Space Ambient Occlusion (SSAO) implementation

Hair modeling

Hair modeling (ad-hoc method, following a simulated falling particle)
