METHOD FOR GENERATING DATA PERMITTING THE REPRESENTATION OF A SCENE BY A MULTIRESOLUTION VIRTUAL REALITY SYSTEM

摘要

The invention relates to a method for generating data for representing a scene by a multiresolution virtual reality system having level of detail management (LOD), comprising the following steps: (a) reading an initial vectorial data set into the memory; b) analyzing the data in order to form a first object set to be represented with a single level of detail, a second object set to be represented with at least two levels of detail, and a third object set that is not to be represented; (c) reading a number of meshing and level of detail parameters; (d) converting each object of the first set into a single multi-faceted meshed model; (e) while using the parameters having been read in step (c), converting each object of the second set into at least two multi-faceted meshed models corresponding to at least two levels of detail (LOD); (f) saving a set of meshed models created in steps (d) and (e) in the memory while associating level of detail information of choice to the models.
