vtkColorTransferFunction

Section: Visualization Toolkit Filtering Classes

Usage

vtkColorTransferFunction is a color mapping in RGB or HSV space that uses piecewise hermite functions to allow interpolation that can be piecewise constant, piecewise linear, or somewhere in-between (a modified piecewise hermite function that squishes the function according to a sharpness parameter). The function also allows for the specification of the midpoint (the place where the function reaches the average of the two bounding nodes) as a normalize distance between nodes. See the description of class vtkPiecewiseFunction for an explanation of midpoint and sharpness.

To create an instance of class vtkColorTransferFunction, simply invoke its constructor as follows

  obj = vtkColorTransferFunction
