Abstract: A kind of progressive three-dimensional mesh generation algorithm was studied. Under the premise of a fixed resolution and to obtain a higher quality of three-dimensional model, an improved algorithm for the progressive meshes based on quadric error metric was presented. The algorithm used a contour protection and produced a 2-adjacent filed index. Experimental results indicate that the model produced by the algorithm is better than others in literature.
