@warrenm @Peter_shirley Is the radial pattern on the floor-sphere intentional? Also there is an extra pattern there in the reflection!

@Peter_shirley@ApoorvaJ Yeah, saw that. Not sure. I think it’s turning up in @mhorga_ ‘s renders too. Worse at lower sample counts. -
@warrenm@peter_shirley@apoorvaj in my case the ripples seem to be smaller but I haven’t finished the raytracer yet https://raw.githubusercontent.com/mhorga/mhorga.github.io/master/images/raytracing5.png … -
@mhorga_
@warrenm@Peter_shirley@ApoorvaJ Had that one as well. Bounce ray intersecting with object itself. Make t_min > 0 for world->hit() -
@Dghelneshi @mhorga_@Peter_shirley@ApoorvaJ Feels right. I had a vaguely similar case when doing <= instead of < against the ray params.

Cool! But why did it took one hour for such a small image?
-
It's been a while, but I think my recursion limits were insane. Also, that banding is due to numerical issues I later fixed.
-
Oh ok I see! I would be curious to see how fast it would be with Metal kernels! BTW, your MBE book is great and really helpful!

@warrenm :O 1 hour?! :O This is why we need GPUs, that would be realtime. Have you profiled it? -
-
@mhorga_
@warrenm I’m not sure it’s easier, the CPU is a lot more flexible. But it’s so much faster it’s worth the restrictions :) -
-
@mhorga_
@warrenm well, if you’re waiting 1 hour for a render it’s probably easier too tbh :D
