AccumulatedAttribs Class Reference

This class is used by the SceneGraphReducer to maintain and accumulate the set of attributes we have encountered on each node that might eventually be applied to the vertices at the leaves. More...

apply_to_node()

void AccumulatedAttribs::apply_to_node	(	PandaNode *	node,
		int	attrib_types
	)

Stores the indicated attributes in the node's transform and state information; does not attempt to apply the properties to the vertices.

Clears the attributes from the accumulator for future traversals.

collect()

void AccumulatedAttribs::collect	(	PandaNode *	node,
		int	attrib_types
	)

Collects the state and transform from the indicated node and adds it to the accumulator, removing it from the node.
