[producer-users] Stereo and ProducerOSG

[Scott Senften]

I am in the process of converting a fairly complex application from
osgProducer to ProducerOSG.  The one piece of functionality that appears to
be missing is the management of stereo.  I have brought this up directly
with Don and wanted to get a wider view of this as he contemplates how to go
forward.

In osgProducer in stereo, we have the idea of a left and right cull
visitor.  It is not clear how critical that is in the general sense, but we
use it, among other things, to manage textures for direct volume rendering,
specifically to determine which textures need to be loaded onto the card
before the rendering pass begins.  It is not a common case, but we have seen
corner cases where a bounding box is culled by the one and not the other.

So my question to the audience is how are you using stereo and what pieces
of the culling do you depend on and how, specifically, do you have cases
that may require a left and right visitor.

Thanks

Scott
