[Insight-users] Create 3D volume from a closed surface?

[Blue Moon]

Hi All,

I need to create a distance map surrounding a 3D object represented by a 
closed (VTK) surface. For this purpose, I need to first create a 3D volume 
from the 3D surface, in which voxels within the surface are 1, and those 
outside are zero. I am currently using vtkOBBTree to determine if a point 
is inside/outside the surface. It's slow, plus for unknown reasons it fails 
to create correct output. What is the most efficient/robust way to create 
such volume? Any advice would be much appreciated.

Best,
BM
