[vtkusers] 3dim -> 2dim image to register

[Bernhard Mayrhofer]

Hi,

I have two 3D datasets and i want to register points using color information. I thought about finding points around an initial point usind vtkPointFinder, converting xyz to 2dim pixelvalues. I intend to pass this to a ITK image, which i can register using some ITK-classes. Now for me it is interesting if there exists somewhere methods which makes this procedure easier and faster. E.g. I used vtkPointLocator before, and found that it is slow with large data sets. I assume that my idea is very inefficient. In short words: I want to create images which I want to register (with ITK). Is there an easy and fast way to do this?

Thanks
Bernhard
