Expand description

Smart pointer for OpenGL 2D texture memory with reference counting.

Required methods

Provided methods

Allocates memory for ogl::Texture2D object.

Parameters

  • arows: Number of rows.
  • acols: Number of columns.
  • aformat: Image format. See cv::ogl::Texture2D::Format .
  • autoRelease: Auto release mode (if true, release will be called in object’s destructor).

C++ default parameters

  • auto_release: false

Allocates memory for ogl::Texture2D object.

Parameters

  • arows: Number of rows.
  • acols: Number of columns.
  • aformat: Image format. See cv::ogl::Texture2D::Format .
  • autoRelease: Auto release mode (if true, release will be called in object’s destructor).

Overloaded parameters

  • asize: 2D array size.
  • aformat: Image format. See cv::ogl::Texture2D::Format .
  • autoRelease: Auto release mode (if true, release will be called in object’s destructor).

C++ default parameters

  • auto_release: false

Decrements the reference counter and destroys the texture object if needed.

The function will call setAutoRelease(true) .

Sets auto release mode.

Parameters

  • flag: Auto release mode (if true, release will be called in object’s destructor).

The lifetime of the OpenGL object is tied to the lifetime of the context. If OpenGL context was bound to a window it could be released at any time (user can close a window). If object’s destructor is called after destruction of the context it will cause an error. Thus ogl::Texture2D doesn’t destroy OpenGL object in destructor by default (all OpenGL resources will be released with OpenGL context). This function can force ogl::Texture2D destructor to destroy OpenGL object.

Copies from host/device memory to OpenGL texture.

Parameters

  • arr: Input array (host or device memory, it can be Mat , cuda::GpuMat or ogl::Buffer ).
  • autoRelease: Auto release mode (if true, release will be called in object’s destructor).

C++ default parameters

  • auto_release: false

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

Parameters

  • arr: Destination array (host or device memory, can be Mat , cuda::GpuMat , ogl::Buffer or ogl::Texture2D ).
  • ddepth: Destination depth.
  • autoRelease: Auto release mode for destination buffer (if arr is OpenGL buffer or texture).

C++ default parameters

  • ddepth: CV_32F
  • auto_release: false

Binds texture to current active texture unit for GL_TEXTURE_2D target.
