2D array of ids, used for picking.
An 2D array where each element is the id of an entity drawn at the given pixel. The access is not specified in this class. The effective/concrete subclass vtkContextBufferId stores the whole buffer in RAM. The access to a value is fast and independent of the OpenGL. However it requires to first fill the whole buffer by transferring the buffer generated by OpenGL from the VRAM to the RAM. It is inefficient if the context of the scene changes during interaction.
The effective/concrete subclass vtkOpenGLContextBufferId keeps the buffer id on the VRAM in a texture image. The access to a value is slower than a simple read access to an array but it does not require a large transfer of data from the VRAM to the RAM.
