[vtkusers] HELP WITH vtkOBBTree::IntersectWithLine(...)

[Christos Panagiotou]

guys

I have a volume (which is not staigthforwart - its a litle complicated 
model, actualy it represent a human liver)

I have a series of rays casted from the center of mass of the volume (so 
i have the first point (centroid) and the last point of each ray)

I want to detect intersections with the volume for which I have created 
an vtkOBBTree.

I use IntersectWithLine(rayStart, rayEnd, tolerance, 
t,intresectCoordinate[3],cellParametricCoordinate[3],subId) method
and I get some results.

The problem is that the results I get are the first intersections with 
the volume. Is there any way to get ALL points
(sequence of entrance and exit points) of the volume that are 
intersected with this line?

I saw that there is a method called 
IntersectWithLine(raystart,rayend,*vtkPoints,cellIds) . Does this do 
what I want?

If you have any suggestions or if you have counter a problem like this 
before I would really appreciate your
help as I am running out of time with a project and it is the last thing 
I have to do!

thanks indeed
christos
