Detailed Description

Root transform for a group of diguy instances, allows each camera to have it's own transform.

Transforms position to camera position so that instance spatial data can be camera-relative (i.e. fit in a float32)

osg::Object * diguyOsgInstanceRootNode::clone ( const osg::CopyOp &  copyop = osg::CopyOp::SHALLOW_COPY )

virtual

Clone this object.

bool diguyOsgInstanceRootNode::computeWorldToLocalMatrix ( osg::Matrix &  matrix, osg::NodeVisitor *  nv  ) const

virtual

Transform to position relative to camera.

Used here to strip out the translation portion of the view matrix to allow camera relative rendering of instances
