In the seismic model and forward, building complex 2D and 3D seismic models by making use of the known or virtual information is of great importance to the subsequent seismic modeling, binning analysis and rational design of geometry system. It also offers a tool for the interpretation of seismic data processing and provides the necessary infrastructure for inversion methods. This paper briefly describes some algorithms of building the seismic model and computer visualization according to the feature of sei...
