Three-dimensional Virtual Scene Editing System

In the 3-Dimension Graphics area, there are three important research directions: 3-Dimension Graphics Modeling, 3-Dimension Graphics Rendering and 3-Dimension Scene Graph Editing. Especially in the 3-Dimension Graphics Rendering and 3-Dimension Graphics Editing fields, there is a lot of inefficiency about the Real-Time, Systematicness and Interaction. The dissertation based on the inefficiency above, and devoted to research of the 3-Dimension Graphics Rendering and Interaction, and make great achievements in Real-Time, Systematicness and Interaction aspects. The dissertation has accomplished these functionalities: 0 a complier that interpret the VRML file into the Scene Graph of the Scene Database, ?Rendering the Scene Graph, ?Select and Operate the Scene Node. And the system has been applied to the Virtual Studio System that has praised by all the TV Stations successfully.
