Detailed Description

2D Transfer function container.

Manages the texture fetched by the fragment shader when TransferFunction2D mode is active. Update() assumes the vtkImageData instance used as source is of type VTK_FLOAT and has 4 components (vtkVolumeProperty ensures this is the case when the function is set).
