Expand description

Smart pointer for OpenGL buffer object with reference counting.

Buffer Objects are OpenGL objects that store an array of unformatted memory allocated by the OpenGL context. These can be used to store vertex data, pixel data retrieved from images or the framebuffer, and a variety of other things.

ogl::Buffer has interface similar with Mat interface and represents 2D array memory.

ogl::Buffer supports memory transfers between host and device and also can be mapped to CUDA memory.

Required Methods§

Provided Methods§

Copies from OpenGL buffer to host/device memory or another OpenGL buffer object.

Parameters
  • arr: Destination array (host or device memory, can be Mat , cuda::GpuMat , std::vector or ogl::Buffer ).

Copies from OpenGL buffer to host/device memory or another OpenGL buffer object.

Parameters
  • arr: Destination array (host or device memory, can be Mat , cuda::GpuMat , std::vector or ogl::Buffer ).
Overloaded parameters

Creates a full copy of the buffer object and the underlying data.

Parameters
  • target: Buffer usage for destination buffer.
  • autoRelease: Auto release mode for destination buffer.
C++ default parameters
  • target: ARRAY_BUFFER
  • auto_release: false

Binds OpenGL buffer to the specified buffer binding point.

Parameters
  • target: Binding point. See cv::ogl::Buffer::Target .
