CustomDataTag Class Reference

#include <lib_customdatatag.h>

Inheritance diagram for CustomDataTag:

Detailed Description

CustomDataTag contains data attached to each mesh vertex or each polyvertex. The CustomDataTag is automatically registered by implementing CustomDataTagClassInterface. While each CustomDataTagClassInterface implementation registers a specific CustomdataTag whith the provided plugin id (returned by BaseTag::GetType()) all CustomDataTags are instances of Tmeshattribute. In the case of polyvertex data storage the indexing follows the CPolygon pattern.
