makVrv::DtModelInstance Class Reference

The base class for all model instances.

The details required to draw a model, such as geometry, filename, scale, or texture are provided by a DtModelDefinition. A DtModelDefinition is a set of parameters, whose names and types are defined by a DtSchema. The DtModelDefinitionManager saves and loads model-definitions and schemas and maintains settings for model instancing and caching. Model-definitions and schemas are distributed, but not by the usual agent mechanism. Instead, the DtDeSharedState distributes them directly.
