It's difficult to build a 3D stratum model based on surface model because the stratum is multi layer structure. For example, Shape from planar contours is often used in stratum modeling but correspondence problems、tiling problems and branching problems are difficult to be solved. Volume elements can describe both surface and interior of the model. In this paper, a method based on tri prism is used to build a stratum model. The algorithms of sections and incisions of model are presented here in detail. This...

It's difficult to build a 3D stratum model based on surface model because the stratum is multi layer structure. For example, Shape from planar contours is often used in stratum modeling but correspondence problems、tiling problems and branching problems are difficult to be solved. Volume elements can describe both surface and interior of the model. In this paper, a method based on tri prism is used to build a stratum model. The algorithms of sections and incisions of model are presented here in detail. This method is perfect to model the stratum of layer structured. Some virtual operations of stratum can be easy realized in computer. The results of application show that the approach introduced here is practical and effective in 3D stratum modeling.

The research of automatic modelling on three-dimension (3D) digital stratigraphic framework is a preliminary approach to the 3D automatic modelling of geologic bodies. Based on doring data, the automatic modelling was divided into two processes independent each other in the perpendicular and parallel directions of stratigraphic interfaces by numerical and non-numerical calculation such as digitization, trigonometric division and stratigraphic correlation. At first, linear interpolation was used to model stratigraphic...

The research of automatic modelling on three-dimension (3D) digital stratigraphic framework is a preliminary approach to the 3D automatic modelling of geologic bodies. Based on doring data, the automatic modelling was divided into two processes independent each other in the perpendicular and parallel directions of stratigraphic interfaces by numerical and non-numerical calculation such as digitization, trigonometric division and stratigraphic correlation. At first, linear interpolation was used to model stratigraphic framework cells automatically. Then, the models of framework cells were conformed according to numerical relations among them so as to form stratigraphic framework bodies.
