Real-time DirectX 11 foveated raytracer using Tobii eye tracking technologies to reduce the number of cast rays and thus traversed scene geometry

raytrace-et

Real-time foveated raytracer using an EyeX controller with the EyeX SDK to render parts of a scene in higher resolution; depending on where the observer is looking by tracking his/her gaze.

When developing a real-time raytracer, I ran into issues with my older video card no longer keeping up to speed. I optimized the raytracing to make use of foveated graphics by only rendering the part of the framebuffer (where the observer is looking) at high-resolution, thus only having to compute a fraction of the rays and taking most of the load off my graphics card.

For the most part implemented in C++ using DirectCompute.

raytrace-et's Issues

Error in pointlighting made apperent by world transform

Only store two of the barycentric coordinates.

The third may easily be calculated using the first two.

View matrix is being updated on a per-fov basis

Might as well be updated on a per-frame basis.

Use Perl for build-script

...for the .tex-document.

Fork for dv2519

Ugly <stdafx.h>-include in DDSTextureLoader.h.

Create seperate project to compile DDSTextureLoader into static lib.

Model- to World-space transform

DirectInput or equivalent mouse support

Support resizing of window (WM_SIZE)
