3D -3D rigid body image registration

Hi everyone

I know Matlab can perform intensity based 2d image registration; But is it capable of 3D-3D image registration? Lets say between two .STL files?

Please give your thoughts

Did you find a solution? I would like to know for my own project :)

If you can read in STL files, in matlab, and access all of the co-ordinates/angles to change it using axes transformations, then yes, you can.

However! If you register a CAD model, you run the risk of changing it in subtle ways and breaking it completely. - I've used conversion programs and found that they didn't produce a reliable output.

Perhaps I also feel it will take ages for simulating it. I am looking to register MRI generated .STL model and a Laser scan again .STL. I reckon there are about 40000 oiints in each model

While I might be a bit late to the party on this, have either of you gotten good results with registration between two STL files? This is relevant to my current PhD research.
