[vtkusers] Image from 3d Data

[Bernhard Mayrhofer]

I habe a xyzrgb data. I have stored the color information in polydata scalars. Now i want to use only the color information in an image. I need the image around a specific points. I thought about  find the points around them with vtkPointFinder, afterwards i can put a grid on them to obtain an image. I´m wondering, if there is another way. Can i use a renderer to get a image. A "screenshot" rendered image would be perfect for my purpose.

Thanks
Bernhard
