Stereoscopic vray physical camera

[vlado]

Yep, needs to be in the [maxroot]\plugins\vrayplugins folder like it says in the readme.

any hint on how its supposed to work? I threw the helper into a scene along with a vray camera and a teapot. I'm getting multiple teapots, but thats about it. Is that all there is to it? Is this something you look at with 3d glasses?

oh stupid me. I should've read the readme.

You should cross your eyes until you see a composed image in the middle.

heh didn't work. I even tried the 3d glasses I stole from the avatar flick

[vlado]

You would usually need some kind of specialized program or hardware to overlay the two views into one stereoscopic image (there are many ways to do that, ranging from shutter glasses and red/cyan glasses to specialized monitors); crossing your eyes also works but only for small images. We might also build such capabilities into the V-Ray VFB in the future.

Thanks Vlado this is fantastic! I especially like being able to use the vray focus to adjust the convergence. One question though: We're doing active 3d where you need two full renders as opposed to the side by side passive style...could the helper render one image after the other (perhaps just naming them l and r, or 1 and 2...whatever...)?

Thanks again, and happy holidays btw~

Is there any difference in the end? When rendering side by side, you save on scene preparation times, and also irradiance maps/light cache is consistent for the two frames.

Could the helper render one image after the other (perhaps just naming them l and r, or 1 and 2...whatever...)?

Not this one - it just modifies the way camera rays are generated.

I was wondering the same thing.

Strange

I installed the plug-in, but I am not getting any results. I get 2 images with 2 totally different perspectives. I am running 3ds MAX 2010 and the latest v-ray build.

It might be that the eye distance as specified in the plugin is too large for your case.

cool. is it possible to have a more customizable version. like full integrated into the camera and not a helper? that way we could have differnt cams with differnt settings

also would be great to can:

choose between: sidy-by-side (squeezed/unsqueezed), two files with regualr size, interlaced,...
show the near and far range where the stereo effect look ok in the viewport
show the screen in viewport
maybe have a quick preview mode


i really like the way that you only need to calc the scene, prepass etc once. that is great!!!

[vlado]

Thanks for the suggestions; there are several things planned in this regard - the helper is more of a "proof of concept" right now. It will probably end up as additional options integrated into the V-Ray camera, and a modifier for standard cameras.

I just started messing around with multi view rendering. The thing that's the biggest bugger is the render time. You're basically doubling it for stereoscopic render. I was curious if its possible to have v-ray render both views simultaneously. Basically render out one view then shift the pixels over using the depth information for the next view and then render to fill in the wholes. I realize you'd run into some issues with sampled pixels...but it'd save a bunch of time when rendering if possible.

It would look ugly, based on previous results with this technique that I've seen. Also, things like reflections/refractions/hilights are view-dependent and will be different for the different views.
