Additionally,the setting and adjustment of visualization parameters are easy and flexible in SinoVis,achieving interactive rendering of middle-sized volumetric data of 128-3～256-3 voxels under arbitrary voxel classification transfer function.

Three examples of volume elements are given and the techniques using them are illustrated.

<Title>The Walkthrough Technology of 3D Stratum Based on similar triangular prism<Author>(School of Computer, China University of Geo- sciences, Wuhan 430073,China) Zheng,Wei Zhang, Dongmei Dai,GuangmingA 3D geological- entitys visualization method based on volume element of Similar Triangular Prism is put forward.

According to the layer structural features of geological body, the volume element of triangular prism is constructed by plane irregular trigonometric framework.
