// .NAME vtkVolumeRayCastIsosurfaceFunction - An isosurface ray caster for volumes
|
||
|
|
//
|
||
|
|
// .SECTION Description
|
||
|
|
// vtkVolumeRayCastIsosurfaceFunction is a volume ray cast function that
|
||
|
|
// intersects a ray with an analytic isosurface in a scalar field. The color
|
||
|
|
// and shading parameters are defined in the vtkVolumeProperty of the
|
||
|
|
// vtkVolume, as well as the interpolation type to use when locating the
|
||
|
|
// surface (either a nearest neighbor approach or a tri-linear interpolation
|
||
|
|
// approach)
