Hi All,

I'm working on a project that will require the separate output of a depth map for a Phillips 3D stereoscopic display. When I output a Pz layer (with a gain adjustment at render time) I get the odd situation that the depth information is noticably different on objects right next to each other (similar distance from camera). Note the small dots on the tube to the right … they are right on top of each other. And on the left, the table and the people are right next to each other, yet have noticably differnent Pz values.

Also, the ojects are translucent in RGB space … I'm surprised that they look so translucent in depth space.

What am I missing here?

Is there a better way to output a depth map that ends up in 8 bit float?

Thanks,
Robert

Setting the sample filter on your Pz parms on the Mantra rop from Opacity Filtering, to Closest Surface will fix this problem I think.

Thanks!

Now that you mention it … it's obvious!
