From ksujit333 at yahoo.com Sun Apr 9 00:01:13 2006 From: ksujit333 at yahoo.com (Sujit Kuthirummal) Date: Sun Apr 9 00:01:16 2006 Subject: [Pbrt-discuss] Getting Scene Depth Message-ID: <20060409040113.21608.qmail@web60015.mail.yahoo.com> Hi I want to render a scene as seen through some glass geometry (say a glass sphere). I was wondering whether its possible to get the scene point associated with every image pixel, i.e. I want to find out which scene point (x,y,z) is imaged at pixel (i,j). Is there some simple way to get this information? Thanks in advance! Regards Sujit --------------------------------- Talk is cheap. Use Yahoo! Messenger to make PC-to-Phone calls.

The plug-in will pass the coordinates via rays to the film, and write this information as additional channels (wx, wy, wz) of your OpenEXR output file.
