A GPU realtime raytracer, with reflections and refractions. The thing on the background is made out of polygons.
There is not much going on at the scene, except it’s being raytraced at 1000 fps. 
I had a try on screen space reflections, but I noticed it’s limitations and I had to find a new solution to the problem. I think I am a few steps closer to the solution.
Here is the executable, if you wish to try it out, you can move around with WASD and Mouse, or use a joypad.
