Abstract:

We present an algorithm for triangle mesh simplification with additional properties. The method uses envelopes and quadric error metrics to control the simplification together. To ensure the global effect of simplification , we use the envelopes to control the global error. In addition, quadric error  metrics is provided to control the local error ,thus keeping the local features and details of the model In order to keep the model＇s properties （such as eolour and texture） , the parameters of colottr and texture are added into this algorithm.

Key words: mesh simplification, quadric error metrics, envelope, mesh with additional properties
