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 in rendered in order from the furthest osg::Drawable
|
|
from the eye to the one nearest the eye. </BLOCKQUOTE>
