[vtkusers] Generating 3D images from surfaces

Hi,
How about using vtkDataSetToImageFilter?

  Subject: [vtkusers] Generating 3D images from surfaces


  Hi,


  I was wondering if there exists a class which can handle the following problem:


  I have a 3D geometry stored in a vtkPolyData and I would like to generate a 3D image out of it. The image should have a resolution specified by the user. I was thinking about using bounded 2D cut planes through my geometry and and generate a certain pixel value at the position of the pixel, where a triangle from my 3d surface cuts this plane. After generating a lot of these 2d images along a certain axis (the distance of the planes is the diameter in z-direction of the geomtry devided by the resolution of the image in z-direction), I want to combine these images to a 3d image volume. Is there any easier way to handle this?


  Yours sincerly,


  Andreas Lintermann
