Not that I can think of. Test the code (e.g. inside mged type 'make epa
epa'; then render it with 'rt' with and without OpenCL acceleration). Can
you get us a screenshot?
Once everything is working ok you can create a patch in unified diff format
e.g. with 'diff -Nurd' and then submit it to the BRL-CAD patch tracker at:
