GPU pathtracer now with textures

Hi! I added textures and depth of field some time ago but I didn't have time to make a video, so here it is a quick one with some models I found on the web.
Running at 1280x800 with a humble GTX 670
I have an Oculus Rift version too, but as expected, any small movement of your head makes the pathtracing restart, so I guess it's not too useful :) And well, after some tests I don't think realtime raytracing will be used for games at least in the next 15 years.
Hope you like it!

GPU OpenCL Pathtracer


here is the first video of my openCL GPU pathtracer, it's still quite simple, no textures and limited shaders but it's good to see that's working :D

resolution: 1280x800
Triangles: around 410000
GPU: Nvidia GTX 670 (not too good nowadays)

I decided to do that cause I'm interested to see if there's any chance of using raytracing in videogames and vr in the near future. So well, after some tests, I'm not too optimistic, technically is possible, the gpus are getting better and better, but as the resolutions are growing, specially for vr, is more and more difficult to keep up with a good frame rate. But hey, I'll keep on optimizing and we'll see :)
