Descriptive modeling language based on semantic

Aiming at the shortage of current modeling by graphical modeling language, this paper presents a descriptive modeling language based on Semantic.This paper mainly introduces the design principle, modeling primitives to describe the modeling language and the design of the parser, group operation technique in the semantic constraints and the implementation process of this descriptive modeling language. The experimental results show that, the modeling language basically corresponds the thinking and operation habit of users, reduces complexity and difficulty of the virtual scene modeling, accelerate the speed of modeling.
