vtkFixedPointRayCastImage

Section: Visualization Toolkit Volume Rendering Classes

Usage

This is a helper class for storing the ray cast image including the underlying data and the size of the image. This class is not intended to be used directly - just as an internal class in the vtkFixedPointVolumeRayCastMapper so that multiple mappers can share the same image. This class also stored the ZBuffer (if necessary due to intermixed geometry). Perhaps this class could be generalized in the future to be used for other ray cast methods other than the fixed point method.

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

  obj = vtkFixedPointRayCastImage
