Mesh simplification should not only emphasize high compression ratio, but also maximize retention of a mesh representation which is another objective of mesh compression. In one of our 3D projects, in order to pursue the optimization model display, we proposed a new mesh simplification algorithm. This article describes the algorithm based on energy-aware which used to simplify a mesh of 3D model. Our approach has two major contributions. Firstly, we used an optimization method based on energy-aware, which seeks to collect low energy value vertexes of a mesh. Vertex energy is calculated by an energy function that describes the potential energy between the vertex and its directly related vertexes in a space. Secondly, our optimization method transforms a mesh into a series of triangle stripes, and reduces low energy vertexes of those stripes effectively. The process of compression is simple, efficient and adjustable for users. From the result of experiments, we can learn that our algorithm is suitable for processing several kinds of grid, and retains the characterization from original mesh very well. Our approach solved the problem of obvious distortions of a simplified mesh of 3D model, and significantly improved the efficiency of simplification process.
