A framework to manage 3D displays, graphic entities and their updates. Used in the AIS package (Application Interactive Services), to enable the advanced user to define the default display mode of a new interactive object which extends the list of signatures and types. Definition of new display types is handled by calling the presentation algorithms provided by the StdPrs package. More...
