In Web3D, a refined model representation requires a large number of polygons. It is difficult to transmit a large number of polygons on the Internet. It is necessary to compress large amounts of data using model simplification. The model data can then be transmitted efficiently. The receiver can obtain the transmitted data in a form as close to the original model as possible, using subdivision surfaces. We propose a new method of generating control polygons for piecewise smooth subdivision surfaces using an extended QEM as a model simplification. We make the vertices of the simplified model correspond to arbitrary points on the polygons of the original model, instead of making the vertices of the simplified model correspond to the points of the original model. This reduces computational time and minimizes errors between the original model and the subdivided model, when producing control polygons from the original model.
