Detailed Description

Simplify action that replaces shapes within a scene graph with versions that contain fewer triangles.

This class traverses a scene graph and replaces every complex shape with a simplified version.

Constructor & Destructor Documentation

◆ SoShapeSimplifyAction()

SoShapeSimplifyAction::SoShapeSimplifyAction ( SoSimplifier * _simplifier )

Constructor.

The algorithm used for simplifying is defined by the SoSimplifier class that is passed in the constructor.

Typically you will pass an instance of SoDecimator to the constructor. Please see SoDecimator for info about which geometry objects can be simplified.

◆ ~SoShapeSimplifyAction()

SoShapeSimplifyAction::~SoShapeSimplifyAction ( )

Destructor.

Member Function Documentation

◆ apply() [1/3]

virtual void SoShapeSimplifyAction::apply	(	const SoPathList &	path_list,
		SbBool	obeys_rules = `FALSE`
	)

virtual

Initiates an action on the graph defined by a list of paths.

TRUE can be passed for the obeysRules flag if the given path list has the following 4 properties:

All paths have the same head node.
Paths are sorted in traversal order.
If one path ends at node A, no other path continues through A.
No two paths are the same.

These rules will be obeyed by path lists returned by picking and by searches for non-group nodes.

Reimplemented from SoAction.

◆ apply() [2/3]

virtual void SoShapeSimplifyAction::apply ( SoNode * node )

virtual

Initiates an action on the graph defined by a node.
