Hi, I created openCL context with openGLES config , and then use clCreateFromGLTexture2D function failed, do you know why ?

kongya

Hi

In android, I created cl context from gl like this :

cl_context_properties props[] = { CL_GL_CONTEXT_KHR, eglGetCurrentContext(), CL_EGL_DISPLAY_KHR, eglGetCurrentDisplay(), CL_CONTEXT_PLATFORM, clplatform,0);

clCreateContext(props,1,&device,NULL,NULL,NULL);

and then create opengl texture, this texture can be used .  After that , I want to use opencl to calculate this texture, so I do like this :

clCreateFromGLTexture2D(clContext, CL_MEM_READ_WRITE,GL_TEXTURE_2D, 0,texturename ,&errNum);

And this function failed, the errNum returned CL_INVALID_GL_OBJECT , and I do not know why , Can you help me  ?

Thanks

    Aren't your texture parameters supposed to be specified before you create the texture store ? I would validate that you are not getting GL errors. I've experience cases wherein if I did not have the call to set the texture parameters prior to calling glTexImage* I would end up getting an invalid texture.
