Development Of Geological Body Visualization System Based On Opengl/vc++

This article mainly do research on the rhetorical model and basic algorithm of the visualization of 3D(Three-dimensional),then use them to the process of 3D visualization of geological body, discuss the basic model,the visual method and basic algorithm,to the character of geological body , improve some algorithm,and made forcasting with the relative methods of geological statistics.This article raise a new visualization method basing on the regular Grid. The method of this article which has improved the traditional Tri-prism Visualization method has been well used in this systerm;This article has made visualization on the curved face of groundwater level ,and it has made a good application in this system.In addition,this article has develop a new frame of OpenGL,In the design of the frame,we separate the class of visualization from the software frame and overcome the defect that the class of visualization and the drawing process are in the same view class.This article add the vein chartlet to strata,it makes the display of stratigraphic attributethe more clearly and the operation more simply. Lastly,this article has made computer implementation on the geological system visualization and attains a satisfactory result.
