Abstract

A method and system for generating a three-dimensional virtual interactive model of an object to be displayed to a viewer. The model is prepared in the form of a VIS tree built up of four types of nodes including primitive nodes indicating geometrical attributes of the object as well as at least one non-geometrical attribute, interaction nodes coding dynamic behaviors of the object, transformation nodes coding transformation behaviors of the object and operations nodes coding combinatorial operations to be performed on a combination of at least one of the primitive, interaction and transformation nodes. The VIS tree constructed in this manner has a small file size, such that a user can view and interact with the model over a network without high link bandwidth requirements.

Dependent claims

A method of making a three dimensional virtual interactive model of an object to be displayed to a viewer, said method comprising:

a) translating said object into primitive nodes comprising geometrical attributes of said object and at least one non-geometrical attribute of said object;
b) coding dynamic behaviors of said object in interaction nodes;
c) coding transformation behaviors of said object in transformation nodes;
d) coding in operations nodes combinatorial operations to be performed on a combination of at least one of said primitive nodes, said interaction nodes and said transformation nodes;
e) building a tree of said three dimensional virtual interactive model using said primitive nodes, said interaction nodes, said transformation nodes and said operations nodes;
and
f) storing said tree in a virtual interactive solids (VIS) file.
