[vtkusers] Obtain Volume of a 3D Actor

[Meisam Aliroteh]

Hi,

I used a program called binvox to convert OBJ models into volumes. I'm not
sure if this is going to help you or not since the process is a bit long. I
only needed to do this once so it didn't matter to me. Here's how I did it:

1) used binvox to convert an OBJ file to a volume file (RAW format)
2) used AMIRA to convert RAW data to a series of DICOM images (my program
loads DICOM files only)
3) load the volume DICOM data into vtk using vtkDICOMReader
