Abstract
To reserve more important shape features in the low-level model,an improved edge-collapse triangle mesh simplification algorithm was presented.On the basis of Garland's simplification algorithm,the concept of similar curvature was introduced and embedded into the original Garland's quadric error metric,so that the metric can not only measure distance error but also reflect geometric variations of local surface.The experimental results show that the improved algorithm effectively retains the detail characteristics of the model,and obtains a better simplified effect.
