void | cv::ogl::convertToGLTexture2D (InputArray src, Texture2D &texture) |
Converts InputArray to Texture2D object. | |
Context & | cv::ogl::ocl::initializeContextFromGL () |
Creates OpenCL context from GL. | |
UMat | cv::ogl::mapGLBuffer (const Buffer &buffer, AccessFlag accessFlags=ACCESS_READ|ACCESS_WRITE) |
