[vtkusers] ICP with vtkActors

[Sean Richards]

Hello,

I have created a test program for ICPTransform. I create 2 simple PlaneSource objects that are close to being aligned. When I use the PlaneSource objects with ICP the algorithm works fine. An example of this code is in the attached file called PlaneSource-ICP.cxx

I then try to use almost the same code, except instead of putting the PlaneSource objects into the ICP algorithm, I use the actors instead. When I do this, vtk crashes. You can see the code in question in the attached file called Actor-ICP.cxx

Ultimately, I want to be able to use actors as the input to ICP.

Thanks!!

Sean

The debug output from Microsoft Visual C++ when I run Actor-ICP.cxx is:
