// .NAME vtkVolumeRayCastMIPFunction - A maximum intensity projection ray caster for volumes
|
||
|
|
//
|
||
|
|
// .SECTION Description
|
||
|
|
// vtkVolumeRayCastMIPFunction is a volume ray cast function that
|
||
|
|
// computes the maximum value encountered along the ray. This is
|
||
|
|
// either the maximum scalar value, or the maximum opacity, as
|
||
|
|
// defined by the MaximizeMethod. The color and opacity returned
|
||
|
|
// by this function is based on the color, scalar opacity, and
|
||
|
|
// gradient opacity transfer functions defined in the vtkVolumeProperty
|
||
|
|
// of the vtkVolume.
