A method, computer system and computer program are disclosed for representing a first surface at multiple levels of resolution. The first surface is partitioned into nodes with one or more boundaries, each level of resolution having a subset of the boundaries. A second surface may be classified against the first surface. Surfaces and the model may be decimated. Portions of the surfaces may be loaded from persistent memory on demand and removed when no longer required.

[ What is claimed is:] [1.]1. A method for modeling one or more physical objects on a computer system having a processor, a memory, a persistent storage system, at least one input device, and at least one output device, the method and a model being stored on a computer-readable media, the method comprising:representing the model at multiple levels of resolution wherein a first surface of the model is represented at multiple levels of resolution, the first surface comprising zero or more zero-cells, zero or more one-cells and one or more two cells, including the steps of:partitioning the first surface with one or more boundaries, each level of resolution having a subset of the boundaries;partitioning the first surface into n.sub.i nodes at resolution level-i using the level-i subset of boundaries;associating each level-i+1 node with a unique level-i node;associating with each level-i node the level-i+1 nodes associated to the node;associating with each level-i node a subset of vertices that are critical at resolution level i;designating each node at resolution level d a leaf node;associating each simplex to a unique leaf node; and associating with each leaf node the simplices associated to that leafnode; andwherein each node except the leaf nodes has a subtree, further comprising splitting the original tree into new trees and associating each new tree with a new cell;presenting the model to the at least one output device; andperforming an operation using the model as input, the operation selected from the set including rendering the model, displaying the model, displaying at least one aspect of the model, displaying the topology of the model, determining the surfaces that bound a volume of the model and displaying an indication of which surfaces bound said volume of the model, determining the surfaces that lie within a volume of the model and displaying an indication of which surfaces lie within said volume of the model, determining fluid flow between compartments of the model, and analyzing geological properties of a geological formation modeled by the model.
