<DIV id=RTEContent> <DIV id=RTEContent> <DIV id=RTEContent> <DIV>Hello,</DIV> <DIV> </DIV> <DIV>I am experiencing really hard times with the zbuffer.</DIV> <DIV> </DIV> <DIV>I have converted the zbuffer to an image on disk. </DIV> <DIV> </DIV> <DIV>Attached at the end of this message is the snapshot of the offscreen render widnow showing the geometry i rendered ( a hemisphere ) and the corresponding zbuffer returned by vtkWin32OpenGLRenderWindow.</DIV> <DIV> </DIV> <DIV>I played with various values of the clipping range, but what i get back is a complete inert behaviour, nothing really seems to change.</DIV> <DIV> </DIV> <DIV>All i get finally is a set of junk values in the zbuffer, which in no way correspond to the geometry i rendered.</DIV> <DIV> </DIV> <DIV>Any explanations for this wierd phenomenon ?</DIV> <DIV> </DIV> <DIV>Thanks in Advance.</DIV> <DIV> </DIV> <DIV>Regards,</DIV> <DIV> </DIV>
