Hello Sir,
I have a doubt:
- I can see four kernles namely "do_pixel", "count_hits", "store_segs" and
"shade_segs" being launched. Which of these uses the xxx_shot() functions
and how? I can see the programs being compiled using clcompileprogram and
then all of them linked together, but I am not able to understand how the
xxx_shot() functions are used.
Also, I have written the code for 'hrt' primitive but I am not able to test
it due to the OpenGL issue :(
Please tell me is there a way I I can compile the code without the use of
OpenGL.
Thanks in advance!
Regards
Shailesh
