METHOD AND DEVICE FOR SELECTING LEVEL OF DETAIL, BY VISIBILITY COMPUTING FOR THREE-DIMENSIONAL SCENES WITH MULTIPLE LEVELS OF DETAIL

摘要

The invention concerns a method for combining visibility computing from a viewpoint, with the selection of a level of detail for each of the nodes of a tree structure representing the geometry of the objects of a scene, so as to increase the level of geometrical detail of the visible objects, and to reduce said level for all the hidden objects.
