Detailed Description

Remarks

CreaseSetContainer interface class

In 3ds Max, subdivision surface creasing is set up around the concept of "Crease Sets" – Groups of edges or vertices which share common crease values. Establishing groups which share common crease values makes it easier for users to manage them and control creasing of various parts of their geometry in unison.

The Crease Explorer allows users to view all Crease Sets in all objects and manipulate them. For convenience in managing them, a hierarchy is created in which each Crease Set resides in a "Crease Set Container", which may contain any number of Crease Sets. A Crease Set Container can be anything in Max which defines a Crease Set. Presently, this includes the CreaseSet and Crease modifiers, as well as the SubdivBox primitive.

Any plugin which defines Crease Sets should derive from CreaseSetContainer, implement all methods of the CreaseSetContainer class and register each instance with the Crease Set Manager using the CreaseSetManager::RegisterCreaseSetContainer method. This will allow the system to access the Crease Sets it contains and display them in the Crease Explorer for the user to examine and/or alter.

When an instance of a CreaseSetContainer is destroyed or removed from the scene, it should unregister itself by calling CreaseSetManager::UnregisterCreaseSetContainer.

When Crease Sets are created or destroyed in a CreaseSetContainer, the CreaseSetContainer should notify the CreaseSetManager via CreaseSetManager::NotifyStructureChanged so that the Crease Explorer, if active, may update to reflect the change.

Any time an existing Crease Set changes in any way, the CreaseSetContainer should notify the CreaseSetManager via CreaseSetManager::NotifyComponentChanged.

A CreaseSetContainer exposes the number of Crease Sets it contains (see CreaseSetContainer::GetNumberOfCreaseSets). Each Crease Set may be queried for its name, as well as its container's name (see CreaseSetContainer::GetCreaseName and CreaseSetContainer::GetCreaseContainerName). Usually, all Crease Sets within a CreaseSetContainer will share the same container name (for example, a CreaseSet modifier in Max returns its name whenever any of the Crease Sets it contains are queried for their container's name), but this is up to the CreaseSetContainer. The Crease Set Manager, which itself is a specialized CreaseSetContainer, wraps all CreaseSetContainers in the system and will return the proper CreaseSetContainer name for any Crease Set in the scene.

For an example of how to implement a CreaseSetContainer, see the SubdivBox plugin in MaxSDK/Objects/PolyObjects/
