[x3d-public] Stereographic Displays

[Andreas Plesch]

Avalon has view modifiers:

http://doc.instantreality.org/documentation/nodetype/StereoViewModifier/

which are applied to a view area which is a portion of the render window
and defined in an Engine component:

http://doc.instantreality.org/documentation/component/Engine/

The Engine component deals with scene independant configuration.

A view area is linked to Viewpoints in the scene.

What is there to learn from this approach ? Decoupling of render mode from
scene content ?

Not sure, just wanted to share.

> There might be other fields (for example depth-of-field, zoom, etc.).
