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 | ( | ) |
Destructor.
|
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:
These rules will be obeyed by path lists returned by picking and by searches for non-group nodes.
