Hello,
I'm attaching a link to my final blog post summarising my work during the
summer. This is the same link that I'm submitting as part of the final
evaluation on the official GSoC website.
Kindly let me know if any changes are required.

Hi,
For GSoC this year I've worked to improve OpenCL support for BRL-CAD. I
started off with accelerating a few of the primitives.
This was basically writing kernel code for the shoot algorithms for various
primitives. I had accelerated EPA just before GSoC began. This was followed
up with ETO an

My laptop was overheating a little. and was also having some issues with

Compilation and installation using 'make' happen as expected. All the tests

Hello,
I got the -z working. However only CPU parallelization is done. In my
build/CmakeCache.txt, the boolean BRLCAD_ENABLE_OPENCL is OFF.
I'm guessing that's why my OpenCL files don't compile. How do I change this?
