I've seen the function "vtkVolumeMapper::SetRGBTextureInput(vtkImageData*)" in the VTK User's Guide (VTK 4.2) I haven't found this function anymore since VTK 4.0 Is there a replacementfor it? I'd like to map a 2D texture onto a volume. I'm using a nightly build of june 2005. Thank you for the help. David Christen
