struct  MatrixPlanesDrawables

Detailed Description

Basic NodeVisitor implementation for rendering a scene. This visitor traverses the scene graph, collecting transparent and opaque osg::Drawables into a depth sorted transparent bin and a state sorted opaque bin. The opaque bin is rendered first, and then the transparent bin is rendered in order from the furthest osg::Drawable from the eye to the one nearest the eye.

const [virtual]
 

Get the distance of a point from the eye point, distance value in the eye coordinate system. Note, not all NodeVisitor implement this method, it is mainly cull visitors which will implement. If the getDistanceFromEyePoint(pos) is not implemented than a default value of 0.0 is returned.

Reimplemented from osg::NodeVisitor.
