Effective GPU-Based Section Visualization in Isosurface of Saturation of Displacing Liquid in a Porous Medium

摘要

One of the methods for analysis of data obtained in computer simulation of the processes of unstable oil displacement is to visual analyze the plane sections of level surface (isosurface) of the saturation of a displacing viscous liquid in a sample of a porous medium. This paper presents an efficient distributed method for plane section visualization on a graphics processing unit (GPU) in a polygonal model of considered level surface. A polygonal model of clipped isosurface is created using a modified "marching cubes" method by means of the developed geometric and fragment shader programs. Based on the solutions proposed, a visualization program complex with an ergonomic user interface was implemented, which can be used in scientific researches, virtual laboratories, virtual environment systems, educational applications, etc.
