Title: Nice Big Stereo Image with transparency Post by: doncasteel8587 on May 23, 2007, 03:05:39 AM (https://fractrace.dev.java.net/files/documents/6137/58320/Render_1179543553971.jpg)

since i haven't produced any stereo images i can't say what's causing this. are you adding an offset to the camera pos (along left and right vectors, equal amount) and pointing them at the same 3d pos some fixed distance away from the centre camera's viewing direction?

I've seen the same issue with several renders and am working on it. You are correct about the camera offsets. I'm keeping the same "look_at" point for both eyes (don't know if this is right or wrong), so the 2D boxes line-up to help align the person's eyes. I think the problem may be the distance between eyes, I think I've got the eyes too far apart, I haven't taken the time to calculate out the distances. One reason is I haven't yet figured out what size the "object" should be. |
