The 3D model lightweight methods play an important role in using 3D models extensively and efficiently.A lightweight method based on detecting simple surfaces was proposed,the simple surfaces of the 3D models such as planes,spherical surfaces and cylinder surfaces were detected in the first place in accordance to the normal vector distribution of the points on the 3D model,then these simple surfaces were expressed by some parameters in order to decrease the size of the 3D models.As the simple surfaces composing the 3D model could be fragmentary,boundary points of the simple surfaces were recorded as a supplement to the method which expressed the simple surfaces by some parameters,the new method expressed intact simple surfaces and fragmentary simple surfaces exactly.The method proposed was a lossless condensation method which was proved to be effective by the experiments,its efficiency was directly related to the types and quantity of the simple surfaces,and artificial models were compressed with high efficiency.
