Detailed Description

Mesh skinning implementation.

Note

A RigGeometry may be attached directly to a Skeleton, or somewhere below a Skeleton. Note though that the RigGeometry ignores any transforms below the Skeleton, so the attachment point is not that important.

The internal Geometry used for rendering is double buffered, this allows updates to be done in a thread safe way while not compromising rendering performance. This is crucial when using osg's default threading model of DrawThreadPerContext.
