Together with Johan Carlberg I’m currently working on implementing a GPGPU ray-tracer using the Compute Shader utilizing DirectX 11. The goal for this ray-tracer is to support real-time rendering in 720p. As it’s currently being worked I can provide executable on request, but to view a samples from the work see below images. In this beautiful pictures you can see Depth-of-Field, reflections, point lights and support for Spheres and Triangles with the possibility to use textures all running in real-time (too various degrees).
Implementation details: C++, DX11 and HLSL with help of Igloo.
