IMeshSelectData Class Reference

#include <istdplug.h>

Class Description

See also

Class ModContext, Class BitArray, Class IMeshSelect, Class Interface, Class GenericNamedSelSetList.

Description:

When a developer gets the LocalModData from the ModContext of the Mesh Select Modifier or Edit Mesh Modifier, they may cast it to this class and use these methods. They may be used to get/set the vert/face/edge selection state of the modifier. This class also provides access to the named sub-object selection sets.

To get a pointer to this interface given a pointer to a modifier use the following macro (defined in AnimatableInterfaceIDs.h ). Using this macro, given any Animatable, it is easy to ask for the interface.

#define GetMeshSelectDataInterface(anim) ((IMeshSelectData*)anim->GetInterface(I_MESHSELECTDATA))

A plug-in developer may use this macro as follows:

IMeshSelectData *imsd = GetMeshSelectDataInterface(anim);

This return value will either be NULL or a pointer to a valid Mesh Select Data interface.
