SCALABLE VISUALIZATION FOR INTERACTIVE GEOMETRY MODELING

摘要

A method, computer system and article of manufacture for visualizing a modelincluding a first surface is disclosed. The methodincludes determining, as the model is being built, the rendering resolution ofa portion of the first surface based on a view frustum fromwhich the first surface is to be viewed and rendering the portion of the firstsurface on the output device using the rendering resolution. Thevertices and edges to be rendered are selected based on the view frustum,using view frustum culling and bounding sphere projection. Thevertices and edges selected to be rendered are tessellated using incrementaland decremental tessellation. The tessellated vertices and edgesare rendered. Predictive techniques are used to estimate future view frustums.Quality may be traded off against performance by adjustingparameters. Material properties are represented. The method. computer systemand article of manufacture allow adaptively visualizinggeological data in a geoscience model by modifying the visualization of ageometry object according to a view frustum from which thegeometry object is to be viewed.
