[vtkusers] Generating 3D images from surfaces

[Andreas Lintermann]

Hi Vidyadhar,

have you ever used this class before? The description says the following:

vtkDataSetToImageFilter is an abstract filter class whose subclasses take as input any dataset and generate image data on output.

Unfortunately, there are no subclasses implemented. It seems as if this functionality is incomplete. Do you have any other suggestions?

Yours sincerly,

Andreas Lintermann

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?
