Title: Stereo (3D render)
Post by: AlecJames on May 24, 2014, 09:10:38 am

Has anyone got any tips for getting the best results from a stereo 3D render?

I just tried a quick test with a sphere, box and a cube and moved the camera around and then over the objects.  The result on my TV is very hard to focus on and something goes horribly wrong when the camera goes over the objects.

I cannot see any settings for the stereo render, can the distance between left and right be set anywhere?
thanks

Well I cant be sure why it's hard to focus on if I cant see an image however anim8or doesn't actually do stereo imaging; I mean you can do it manually but not automatically. So everything is up to really.
Somethings that may be the issue is because the depth you have created (the difference between the distance of the camera in the two renderings) could be much to great. Another thing could be the images themselves being displayed too far apart causing the viewer to have to go slightly cross-eyed in order to see both images as one (the two images on screen are too far apart).

I've been selecting the stereo view and doing a render. I've got the xvid codec installed.  I can create a file that is compatible with my TV, side by side stereo, reasonably sized file in 1080p or 1/2 1080p.  The stereo setup provided by Anim8or (I think) the problem is that it makes the objects appear too close with my setup - hence difficult to focus. I have been experimenting with dimensions / distances but because the render takes so long and the TV is not often available for testing, it takes ages to get any results.

I tried something similar a couple of years ago and did this "manually".  Carmer01R is parent of Camera02L, offset by about 4" (my scaling in affect, 1 Animator unit is 100mm or 4"). Cameras are parallel.  I get better stereo effect results but poor resolution because the only way I know to build the 3D file from the 2 renders is stereo movie maker (the Japanese one) that has limited output formats.  I use 640x480 (1280x720 does not produce a "valid" file for me) and I cannot find how to force it to use the xvid codec.  If I post process the output through xvid miniconvert I get an incompatible file for TV.

I’ve been using a fixed object and moving the camera.  It’s just occurred to me to use a fixed camera and several rotating objects at different distances.  Then look for which object gives the best visual result – next test planned.

Trial, error and patience required....
