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.

Note, not all NodeVisitor implement this method, it is mainly cull visitors which will implement. If the getDistanceFromEyePoint(pos) is not implemented then a default value of 0.0 is returned.

Reimplemented from osg::NodeVisitor.

Create a shallow copy of the CullVisitor, used by CullVisitor::create() to clone the prototype.

Prevent unwanted copy operator.

virtual void osgUtil::CullVisitor::popProjectionMatrix ( )

Re-implement CullStack's popProjectionMatrix() adding clamping of the projection matrix to the computed near and far.

Reimplemented from osg::CullStack.

void osgUtil::CullVisitor::popStateSet ( )
inline

Pop the top state set and hence associated state group.

Move the current state group to the parent of the popped state group.

get the prototype singleton used by CullVisitor::create().

void osgUtil::CullVisitor::pushStateSet ( const osg::StateSet *  ss)
inline

Push state set on the current state group.

If the state exists in a child state group of the current state group then move the current state group to that child. Otherwise, create a new state group for the state set, add it to the current state group then move the current state group pointer to the new state group.
