<br>
I am new to VTK and rendering. I have a rendered depth map from VTK (file attached). What I want is to get the distance of each pixel in this depth map from camera. Can any body tell me how to convert z-buffer values to actual distances from camera. I will really appreciate any help and a sample code snippet to get me started.<br>
Thanks in advance.<br>
