[vtkusers] Problem - How to extract Voxel Data in 3D space containing several objects

[Christian Arens]

Hi there,

i created a 3d scene containing several objects like vtkconesource.
After placing them in a 3d space i want to determine each voxel value 
(x,y,z) of the scene.
Using e.g. the worldpicker deliever only the 2d space and 3d world 
coordinates, but not the data value represented at the voxel.
How do i extract them of the scene?

This picture represent an example of a scene.
I want do determine each voxel value from ymax to y=0 and x=0 to xmax 
for every layer z.

best regards
Chris
