CUDA Pathtracer

This is a simple pathtracer written in CUDA and C++ featuring procedural shapes (sphere, cylinder, disk, cone paraboloid, quad and cube), different material types (lambertian diffuse, GGX specular), a BVH for accelerating ray-scene intersections, as well as support for simple textured scenes and HDRI environments.
