ABSTRACT
This paper discusses the key technology of 3D geological modeling software designing.
Based on corner-point grids, the paper discusses the design of 3D visual & interactive
geological modeling software with fault handing.
This paper prises parts as following :
(1) The paper researches on the fault modeling and stratigraphic modeling with fault. By
using advanced corner-point grids technology to bind fault in corner-point, and describing
fault distribution with deformed quadrilateral mesh, it greatly simplifies data management,
and provides a higher quality of spatial information for the reservoir property modeling in the
future.
(2) The paper applies spatial interpolation method to mesh deformation, so as to generate
gradient corner point grids which have adsorption effect to fault data, and avoid the slow
iteration calculation and unreasonable deformation result by using partial differential
equations method.
(3) The paper discusses the relevant principles and implementation method of the
advanced 3D rendering. It has achieved seamless integration between contours and layer by
using an improved pre-rendering texture technology based on views with high-level shading
