Abstract:

Aiming at slow web loading and model distortion caused by the excessive size of data in the Web/server(B/S) architecture, a parametric NURBS surface model based on the B/S architecture was developed. The feature information of the point model was manually extracted by using a 3-D scanning tool to obtain its feature semantic structure and reduce the amount of model data, and then a B/S architecture was built to transfer the data from the server to the client through the JSON tree structure. Angle-weighted average, similar triangles and other methods were used to achieve parametric deformation of the mannequin. According to the principle of NURBS surface, the high-density points were employed to supplement the control points in the deformation area to construct a smooth human platform deformation surface. This method reduces human body data to form a simplified set of data to facilitate smooth data loading for creating a high-quality NURBS surface based on the B/S architecture.

Key words: Web3D technology, 3-D platform deformation, 3-D scanning measurement, NURBS surface, feature point mark of mannequin
