Abstract: In order to solve some problems such as memory overage even more than system memory and low frames per second in traditional methods, new implementation of PM is proposed which is surface simplification-independent. It decomposes basic operations of simplification and cuts those unnecessary data structure and operations as much as possible and space complexity and time complexity are improved. A simple framework to render multi-models in application is put forward. Experiments show that the new implementation of PM based framework values a lot in rendering multi-models during application.

Key words: surface simplification, progressive mesh, multi-models rendering
