Today’s update is a short one. I ported my raytracer from day 02, to the Nvidia GPU: ha3k-06-raytracer
The visuals are pretty much the same. Incidentally I discovered the striations on the ground disappear if we increase the floating point precision.

Render on the GPU is 30x faster (0.05 fps -> 3 fps). That’s still not very fast.
I didn’t get video working yesterday, or anything else visually new. I will call this one a failure overall, because I have nothing interesting to show off. I learned stuff and made progress though, so it’s not so bad.
Here’s a working video!
