[Radiance-general] 3d Depth of a pixel

[Brajesh Lal]

Hi, 

I need to know the z depth of  each 3d point. I want an output image such that 
color of each pixel stores the info of z-depth of the corresponding pixel . 
in rpict i am confused in syntax. How do i use -z option ?

e.g.
rpict -x ResX -y ResY -z  depth.hdr  -vf  camera.vp  scene.oct > scene.hdr   
 ????

 Best Regards, 
Brajesh Lal
