CONSTRUCTION AND MAINTENANCE OF SCENEGRAPHS FOR INTERACTIVE FEATURE-BASED GEOSCIENCE GRAPHICAL MODELING

摘要

A random access memory and a computer program are provided for interactively constructing, editing, rendering and manipulating geoscience models, including aggregating the functionality of a geometry system and a graphics system, enforcing consistency between the geometry system and the graphics system, and interfacing the geometry system and the graphics system to an application through an integration layer. A material property framework is provided to communicate changes in the geometry or topology to aggregate objects which then determine which graphics objects are affected by the changes and which graphics objects are to be updated.
