|
* @brief A maximum intensity projection ray caster for volumes
|
||
|
|
*
|
||
|
|
*
|
||
|
|
* 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.
