Abstract The true three-dimensional modeling is a common subject in such fields as geology,three-dimensional GIS,scientific visualization and engineering application. This paper has presented a new three-dimensional data model based on TEN, and introduced TEN's generation algorithm and steps. Practical examples indicate that this algorithm can satisfactorily produce the tetrahedral unit grid of the arbitrary shape three-dimensional geological body.
