Abstract: In order to conquer the shortcoming of big calculation and slow speed of the Hoppe’s Edge Collapse Arithmetic, the simplified model is achieved by combining the Edge Collapse with the view-dependent gene. The improved data structure is used to dynamically generate multi-arrangement LOD model. The experimental results show that this arithmetic can not only preserve the important features of the model but also realize the model’s simplification.
