The aggregate functionality of the graphics system and the geometric system, to increase the consistency between the graphics system and geometric systems, one through the integration layer ties the graphics system and geometric systems Methods for engineering and building interactive comprising the step of the application, geoscience model, editing, and expression, a computer program or a computer system is provided. There is also provided a state machine can be can be a phase or geometry changes, and updates only the specified graphics object as visible by the user, to improve the performance. There is also provided a scene graph construction techniques to reduce memory requirements and enhance performance. Transmit or phase change in geometry in particular, by aggregating the object, which the graphic object is also affected by the change later, to determine which graphics object is to be updated, material properties framework There are provided.
