[vtkusers] How to read out voxels values of a structured grid by x, y, z coordinates?

[lynx.abraxas at freenet.de]

Hello again!


Since  nobody  seems to know an elegant way to read out the intensities of the
gaussian splater result (see last post), I'd now try to do it by direct access
to  the  image  data.  But  how  do I read a voxel value corresponding to some
x,y,z?

Many thanks for any help or hints
