Pri-Rend is a homemade Cuda-accelerated ray tracer. I began this month long project as a way to learn how ray tracing works under the hood and to boost my GPU programming skills.
It has support for Loading OBJ's, FBX files, Textures, Phong shading, Anti Aliasing, and a host of other features. I have yet to implement an uber shader, but this project has been abandoned due to school :(.
To use it, load the source code, and change the file name under "main.cu" to be what you want to render.
Included below are some images from differing stages of the Project.
