Currently the parallelization is done per ray. One SIMT thread per ray.

It's probably easier to exploit the per ray parallelism at this point. So
the idea would be to construct and the CSG tree once, and then evaluate it
in parallel for all rays.

You generate a list of segments for each ray. Then you evaluate those
segments according to the CSG tree data to determine the final output.
I hope this was clear?
