How to interoperate with OpenGL using OpenCL interop interface

Shukla__Gagandeep — Tue, 20 Oct 2020 21:45:18 GMT

Hi,

I am porting some cuda code and it uses cuda functions:

cuGraphicsMapResources
cuGraphicsResourceGetMappedPointer
cuGraphicsGLRegisterBuffer
cuGraphicsUnregisterResource and
cuGraphicsUnmapResources

As per my understanding of the code, these functions are allowing cuda code to interact with OpenGL buffers. I understand that there is no direct interoperability between OneAPI and OpenGL and it has to be done through OpenCL interop.

Can you please suggest which functions can I use instead of cuda functions mentioned above?

Regards,
Gagan

Hi,

That's correct, there's no direct interoperability between oneAPI and OpenGL currently. You may refer to the tutorial on OpenCL and OpenGL interoperability in the link below:

DPCT subject matter experts will get in touch with you shortly regarding equivalent DPCPP functions.

Thanks,

Rahul
