I have tried it , but the compile said that I have to call the openGL instruction in host.
But when I call it in host , I have to copy the data from GPU to CPU…
Then I can call the OpenGL with these data to finish the process…
It costs me a lot of time…
So…does anyone know how to avoid copying from GPU->CPU that I could
call the OpenGL instructions with data in device ?
thanks~~! :biggrin:
