Functions#

void cv::ogl::convertFromGLTexture2D (const Texture2D &texture, OutputArray dst)

Converts Texture2D object to OutputArray.

void cv::ogl::convertToGLTexture2D (InputArray src, Texture2D &texture)

Converts InputArray to Texture2D object.

UMat cv::ogl::mapGLBuffer (const Buffer &buffer, AccessFlag accessFlags=ACCESS_READ|ACCESS_WRITE)

Maps Buffer object to process on CL side (convert to UMat).

void cv::ogl::render (const Arrays &arr, InputArray indices, int mode=POINTS, Scalar color=Scalar::all(255))

void cv::ogl::render (const Arrays &arr, int mode=POINTS, Scalar color=Scalar::all(255))

void cv::ogl::render (const Texture2D &tex, Rect_< double > wndRect=Rect_< double >(0.0, 0.0, 1.0, 1.0), Rect_< double > texRect=Rect_< double >(0.0, 0.0, 1.0, 1.0))

Render OpenGL texture or primitives.

void cv::cuda::setGlDevice (int device=0)

Sets a CUDA device and initializes it for the current thread with OpenGL interoperability.

void cv::ogl::unmapGLBuffer (UMat &u)

Unmaps Buffer object (releases UMat, previously mapped from Buffer).
