@joeblew999 and @lynaghk, could you test this branch and see if Mac issue is fixed?

Hmm I missed something it seems. Maybe try now?

Same output, unfortunately.

Alright, fixed. You had run into a latent bug created during a refactor that happened a while ago (for CPU runs). Now it should (hopefully) work :)

[lynaghk]

Yeah seems to have worked on CPU (though no window pops up or anything, not sure if something is supposed to be visible). GPU mode still has issues, though:

15:55:21 $ go run ./examples/bolt
using CPU

111.833µs wrote bolt.glsl
   1.341s evaluated SDF 4069179 times and rendered 62168 triangles with 96.96 percent evaluations omitted
 91.494ms wrote bolt.stl

Odd, i inserted panics all over to catch where it fails. You ran with latest?
