The Implementation of Graphic Constraints for Automatic Text to Scene Conversion

Abstract

The use of constraints in computer graphics has been widely used in computer graphic systems, the constraints can be specified that restrict the objects and determine the relations between them. We present an approach based on visual semantic definition by integration of related theory, advances in NLP and computer graphics technology to generate a 3D virtual environment. In the prototype system developed here, the graphic constraints refer to establishing the geometric relations among the 3D objects. The concept of rigidity of constraints (i.e. restrict the parameters of the position, orientation, etc.) was introduced to handle a set of the objects and their spatial representations.
