ImageVis3D simply maps the local grid coordinate axes to world space axes. So far we ignore any transformation stored in DICOM (or any other format such as NRRD, except for scaling). As long as we were only supporting a single volume this did not matter much but with multiple datasets it does matter I agree. For geometry you can already specify any affine transformation (simply use the transform button in the document explorer).
Ah, I found out (through experimentation), that you map largest local coordinate to 1 in render world space. It shouldn't be too hard now to set up transforms for my polygonal models.
