Research And Application Of Constraint Solution In Virtual Interior Decoration System

This paper is concerned about the constraint solution application in virtual interior decorating system. It studies the meaning of constraint solution, the constraint types and the constraint requirement in the system. It studies the 2D constraint position and 3D constraint position in the system and put forward the constraint solution. Thus it offers a reference model for the application of constraint solution in the interior decorating system. The system has been put into use and got good effect in the practice.1) The significance of constraint in the virtual interior decorating system is related, the interaction process in the virtual interior decorating system is described and the position of constraint solution in process is confirmed . The constraint types in the virtual interior decorating system are summarized and the constraint requirement in the system is analyzed. The body system of constraint application which include constraint analysis, constraint expression, constraint solution is put forward.2) The Geometrical constraint and engineering constraint in the virtual interior decorating system are related. The geometrical constraint priority of 2D constraint position in the system is analyzed, and the constraint-based interaction mode is put forward. The constraint solution algorithm based on interaction semanteme is put forward and the algorithm witch construct topology structure making use of constraint knowledge is put forward too.3) The constraint model in 3D scene of the system is analyzed and constructed. The constraint relationship of interior objects in 3D scene of the system is analyzed. The middle model to face the layout of 3D scene is put forward and the objects dynamic ganging of the layout of 3D scene is studied. The possible constraint conflicts of the laying are analyzed and the process method is put forward. The algorithm of constraint-based placement for 3D scene is put forward too.4) As the application of the above researches, an interior design and demonstrate system Decorator 1.0 is developed. This system has been used in the market and welcomed by consumers.
