[vtkusers] VTKRayCastRayInfo.TransformedIncrement[3]

Hello, VTK experts.
I will appreciate your help with two questions.

1) Where is VTKRayCastRayInfo.TransformedIncrement[3] computed?

It is stored in vtkRayCastStructures.h and used in class
vtkVolumeRayCastIsosurfaceFunction, function CastRay_Trilin():

CastRay_Trilin ( VTKRayCastVolumeInfo *volumeInfo )
	ray_increment = rayInfo->TransformedIncrement;

2) Is there some technique for finding these things without reading the
half the VTK library?

Thank you,
