The code has some bugs in it. I think its improper initialization of the

linfo should run as well. Try running clinfo as root with sudo.
In the past I had issues with the NVIDIA GPU driver not initializing OpenCL
services unless you ran an OpenCL program as root first.
You can also try installing the AMD APP SDK as I suggested in the other
post.

What needs to be done is to implement the boolean evaluation and CSG in
OpenCL. The OpenCL backend has a sufficient amount of ray-primitive shot
tests to go with and the ray traversal is already accelerated with a BVH.
This task requires a background in ray-tracing and OpenCL/C.

don't want to reimplement the whole rendering pipeline in a summer. Believe
me I tried. :-)

zed 2D array
of 1D arrays. To know the range indexes for a given pixel you can access
the offset array 'h' thus: segments(x,y) -> h[y*width+x]..h[y*width+x+1].
So you can copy 'psegs' to CPU memory e.g. into a variable named 'segs'
then traverse it like this:

- in copy_to_gpu you do not initialize gpu_seg->seg_sti.
You need to initialize the seg_sti (primitive id) field properly before
shade ops because this is used to compute normals, determine the shade
material, sha
'stp'.
This might be duplicating some pre-existing functionality in the regular
ANSI C database though.

So to make the code faster without these loops we can either store the dead
solids, and mark them somehow to ignore them on traversal, or we can create
an array that converts from one index (i.e. stp->st_bit) to the other (i.e.
gpu_seg->seg_sti).

If you get working drivers do not to update them. :-)
NVIDIA sometimes messes up on a revision as they usually test on their most
recent cards but sometimes the older cards stop working. I don't know how
the process works on MacOS X though.
