IModelGeometryDynamic

Description

interface Tinman.Engine.Models.IModelGeometryDynamic

Derived from

IModelGeometry

Base interface for model geometries that can be updated at runtime.

To update a model geometry, perform the following steps:

  1. Use any of the following methods to obtain the model geometry data arrays and modify their contents:

  2. Call UpdateRange zero or more times, in order to specify the vertex and index ranges that have been modified in step (1). The IModelGeometryListener.IndicesUpdated resp. IModelGeometryListener.VerticesUpdated methods will be called on all listeners that have been added with UpdateListenerAdd.

  3. Call Model.ColliderDirty if the updated model geometry shall be taken into account for spatial queries.
