This is very impressive.
I remember messing with the Brunetons stuff 7-10 years ago implementing this in a custom ogl/c++ personal project being real proud of the achievement with a nvidia gtx260m card. When I went to share with my community friends, the intel_HD guys were quick to complain of glitches with the projection so I dropped it in disappointment. In retrospec, giving up was a mistake and should have stuck with it because it looked great on my end.
I bring this up because something similar with this sample occurs on the underneath side at close to glancing angles. Today I’m on a nvidia gtx1650 but unsure if Flax choses that or the amd radeon behind the scenes. I’d have to dig into which is being considered default on this laptop with the configured performance settings.
Love this sample though and the LiteWater also I consider to be great examples.
This one, I could spend weeks trying to figure out that material and the two accompanying source files.
Thank you so very much. Very generous.
