Hello,
The OpenCL rt finally works :)
To test my code, could someone please give me some set of commands to
successfully make and run raytrace over an HRT primitive.
I tried:
http://brlcad.org/~Izak/Export_test.png
But 'rt' command fails for this. (*Error: No regions remaining.*)

You need to make sure OpenCL is enabled with 'cmake' (e.g. using
'cmake-gui'), regenerate the Makefiles, and recompile the code with 'make'.
Plus it's "rt -z1".

After setting the environment variables correctly, clinfo and
vector_addition codes are working fine. But the error with "rt -z" is the
same.
Do I need to set any other configuration paths?
How does rt detect opencl?

If OpenCL isn't detected on your system, the OpenCL backend won't be used.
Did you check if OpenCL is properly installed in your system with 'clinfo'?

Hello,
Wait, I think there is some confusion. The argument for OpenCL compilation
is "rt -z1" or "rt -z".
I think it is the second one.
Since "*rcc"* has not been ported yet, I am just creating "*sph*" and using
"rt -z" command:
When I try this, it says

Finally, now all the errors are resolved. deviceQuery' is working fine with
CUDA which hints that OpenCL is also setup.
Now, as I told the 'rt' command and 'rt and 'rt -z1' gives quantitatively
equal results.

I was doing that only but I think I was missing something in the
installations steps.
Finally the rt command works but I am not sure with the 'rt -z1' command.
It is working fine but the output log is similar to the 'rt' command
result. If 'rt -z1' shows an output does it means it is using OpenCL,

Hello Sir,
Thank you for the description. I got a rough idea at first, but this makes
it a lot clear :)
Regarding the OpenGL issue:
I am using CentOS 6 with NVIDIA GPU. I have installed CUDA. The and the
'devicequery' code works fine, which makes me think that CUDA, and hence
OpenCL, is installed

AFAIK OpenCL should work without OpenGL. But you are probably better off
installing OpenGL in the first place. You need to install the drivers
specific to your graphics hardware. Just installing some Mesa libraries is
not sufficient to get accelerated OpenGL support. You can then test if

It’s an option during cmake.

How to disable OpenGL support for 'rt'?
I need the 'rt' and 'rt -z1' to use OpenCL code. But in both the case I am
getting the same error. Is
Not necessarily. BRL-CAD has a variety of windowing methods including direct
X11 (without OpenGL), GLX, and other methods. You will either want to make
sure GLX is installed properly or compile with OpenGL support disabled
(assuming it’s not needed for some other aspect of the OpenCL code).
C
If OpenGL libraries are not installed correctly then shouldn't there be
issue with raytracer launched from graphics window also?

A proper answer to your question requires more information to be provided.
Which operating system and version are you using, if it's Linux which
distro, etc.
