sory for looong delay. i put all my test stuff (scripts, gizmos and scenes) to nukepedia: http://www.nukepedia.com/gizmos/draft-stereoscopic-toolset/ and there is a video that illustrate how use my scripts to export stereo camera fro maya to nuke https://vimeo.com/40015725 hope it would be

A little late to the party, but just wanted to add my 2 cents in case it helps someone make a full dollar :) @Thomas: the process Michael described above is exactly what you need if your starting point is already a world position pass. You should only need the pass rendered for one eye and the

Hi Michael, We're using Arnold. If i have my stereo Pworld passes and stereo cameras in nuke couldn't i make this work? When you say world position projected to screen space isn't that essentially what a Ppass is or are you talking about something more? I tried doing some logic operations

Hi Thomas, you are right the pworld pass is already the first part. We have the screen space and the coresponding world position. But to be able to calculate the disparity you need the screen space position for this particular point viewed through the second camera. It is possible to

Yes, Thoma.. i will post it soon. I just thought to change it little bit after Michael Habenicht mention about no need in extra data except camera`s transform matrix at all.. so he absolutely right actually becouse i can get interaxial and zero parallax info right from camMatrix. I think i

I'm on 6.3v6 and Ocula 3. Unfortunately the errant vertices are so far off (300 px when it should be a 3 px difference) that the correlate average is useless. I'm really looking for an explanation of how to use depth_to_disparity or maybe what i'm doing wrong/why it isn't working in my case.
