* @brief An isosurface ray caster for volumes
|
|
*
|
|
*
|
|
* 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)
