It's possible to not fail affine transformation for a sphere if you transform the ray into the local coordinate of the sphere.

It is, but then he wouldn't have rendered a glitch picture.

Lesson learnt: When you want all threads in a warp to participate in a memory fetch (see Tony Scudiero's GTC presentation "Memory boot camp III"), first make sure all threads are active.

Heh. I have seen much worse than that. In case you need someone to talk with about this we published a couple of articles on gpgpu rectilinear grids some time back. If you eventually publish something with grids I would be interested to look at it.
