Hi, Jana<br><br>Thank you for your suggestion. I tried vtkWindowToImageFilter and SetInputBufferTypeToZBuffer(), but the application returns an error says<br><br>"ERROR: In ..\..\VTK\IO\vtkBMPWriter.cxx, line 109<br>vtkBMPWriter (00C53A10): BMPWriter only accepts unsigned char scalars!"<br>
<br>I then changed the image writer to vtkJPEGWriter, but it pops similar error says the writer only accepts unsigned char input.<br><br>I have no idea how z buffer works in vtk. Can you help me?<br><br>Thank you very much. I greatly appreciate your help.<br>

Hi, Jana,<br>
<br>
Thank you for your reply.<br>
<br>
No, I don't want to color my input model. I only need the depth information<br>
visualized. The intensity of a pixel varies as the depth changes at<br>
corresponding point on my model surface. Thus the pixel will become darker<br>
or brighter.<br>
<br>
To have an idea of how it looks like, you can google it.<br>
<br>
Best wishes<br>
Wenlong<br>
