VrayStereoscopic Helper

[jordanw]

I was wondering why the stereo settings were implemented as a helper rather than as options in the camera rollout in the render settings? Is there any logic to this as I cant figure out why you would want multiple VrayStereoscopic helpers in a scene. We are using RPM for pass management and having the stereo settings in the render settings makes much more sense.
Also when you hide the helper the stereo settings do not get applied. Is this a bug or by design as it is quite frustrating.
One last thing, it would be great to be able to pick two cameras as the stereo pair rather than extrapolating the left and right from one camera. This would allow for using a stereo pair of cameras that come from our tracking department and still get all the benefits of using the shared rendering speed ups.
Also a disparity Render Element would be awesome!
Thanks for listening

you can use the "vray stereo rig" to define a camera pair manually.

o yeah, i forgot about that the stereo rig.

There are a couple of reasons why it is a helper; one is that I wanted it done completely with the V-Ray SDK, independent of the main V-Ray renderer so that its source code can be distributed as part of the V-Ray SDK, and so that it can be updated independently if needed; the other is that I could not figure out a way to do it as a camera modifier (which would have been my preferred way of doing it). I specifically didn't want it in the renderer settings, as then it would have had to be hard-coded into the main renderer (requiring a full release of V-Ray if any changes have to be done), and also because the renderer settings are getting quite crowded

It might still be possible to do it as a camera modifier, something that I still want done, if possible...

Thanks for the info Vlado. That makes sense now A camera modifier would be more logical but isnt really a huge issue.
Is the behavior of it not working when hidden a bug or by design?

If you want to render for an auto-stereographic display, one that doesn't need glasses then you need 8 views, you can just put 3 stereo helpers in the scene (although not tested this...)

I do miss a stereo modifier !
I often have 10 cameras in the same scene.
Of course stereo settings can't be the same. So a modifier over each camera would be really cool. (Today i have to make as many 3dsmax files as camera).

Besides it would be great to have 2 virtual cameras generated by the stereo rigs. They are usefull when using Kostasoft driver to output in real time a stereo viewport on a 3D monitor : http://www.maxunderground.com/archiv...ic_viewer.html That is a killer way to setup a Stereo camera ! You can set eyes distance, nodal point in realtime in your scene

Please oh please

[vlado]

There is the VRayStereoRig controller which gives you two regular cameras that you can control independently, and use for other purposes if needed.

V-Ray RT can also give you a stereo preview on a 3D monitor with options to adjust eye distance and target point, but you'll have to copy the settings manually from the RT dialog to the VRayStereoscopic helper afterwards.

Missed that

But i just tryed and i can't get it working
I have a Real 3D TV as a second monitor. (Not a Nvidia screen).
I've setup this monitor as my Primary one.

When i use OpenGL mode i get :
The current display configuration does not support the selected stereo vision mode !

Should i use another mode ?
Does it only work with Nvidia compatible screen ?

Thanks

[vlado]

It depends on what kind of monitor you are using. I'm not familiar with Real 3D TV in particular, but OpenGL stereoscopic mode is supported only by Quadro cards from nVidia, and some ATI models.
