A 3-Dimensional (3-D) object modeling technique with mesh simplification based resolution adjustment is proposed in this paper. Polygonal models which are widely utilized for the modeling of 3-D objects are taken as basis, making use of the polygonal structure and vertex coordinates for the display of 3-D models. The mesh structure obtained by the collection of polygons can be displayed in filled, colored, or texture mapped fashion. Rotation, lighting and zooming functions are supported to enable user interaction with the 3-D model. The amount of polygons and vertices of a model is proportional to the resolution as well as data quantity, resolution and data increases with the number of polygons. In this paper, we propose a new simplification and refinement algorithm to utilize resolution, and hence data amount, adjustable 3-D modeling so that data resolution can be changed according to access constraints.
