A rudimentary (and slow) software ray(path)tracer. Made from scratch in C++
- Live ECS based editor.
- Scene system with JSON based load/save
- GPU accelerated (compute shader) raytracer with Spheres and Triangle intersections
- .obj model loading
- Bounding volume hierarchy generation with Surface Area Heuristic split
- Depth of Field
- Simple ray diverge Anti-Aliasing
- Simple skybox
