For improving velocity of Mesh Simplification and realizing continuous Level of Details (LOD)

this paper uses spheres to segment vertexes of models

and control the radius of each spheres by a cluster error threshold

then cluster the vertexes in each sphere by a minimum error-based cluster algorithm.The experimental results show that this method can simplify model meshes with a comparatively high speed and high fidelity

and provides a solution to continuous LOD

so it is effective and useful.
