Abstract�� The algorithm of triangle mesh optimization was provided by optimizing situation of the triangle vertices. The situation optimization is based on the discrete smooth interpolation(DSI). The compensated triangles were added to the vertex adjacent to the boundary during interpolation iterative computation in order to improve the optimization effect. The control point constraints were implemented in the interpolation algorithm in order to maintain the geometry detail characteristic of the primitive triangle mesh model. The algorithm in this dissertation was compared with the additive weighting Laplace algorithm in effect and applicability. With the improved algorithm, the adjustment triangle mesh both maintained the primitive mesh partial detail characteristic and improve the triangle quality well.
