Application of Software Engineering Method to 3D Modeling of Weapon

Aiming at the need for 3D modeling of sophisticated weapon, the development methods of software engineering such as waterfall model, transform model and increment model were analyzed and compared, and the increment model was introduced into 3D modeling for weapon. Firstly, the 3D model was divided into different increment units based on the information gained from requirement analysis; secondly, the increment units were designed in detail, and the development and test of the units based on Multigen Creator were completed; finally, the units were assembled and tested. Application result proves that the method can improve the repetitiousness and development efficiency of model, and satisfy the requirement for reality and real time in visual simulation system.
