چکیده
G Also associated with The University of Burgundy, LE2I Laboratory, 12 Rue de la fonderie, 71200 Le Creusot, France Abstract This paper presents a method for enhancing photo-realistic models by creating a new multiresolution representation of models for use during display. From the original model, a lower resolution is calculated by collapsing an edge that connects two vertices in the model. The edge collapsing process is controlled in a pattern space. This process can be extended to take into account any information. This process computes the edge lengths in the feature space throughout the model and collapses the shortest edge to one vertex. At each step of the data reduction, a data structure known as dendogram is built allowing resolution selection during display. Hardware performance is computed during display and the most adequate resolution is selected to reach a desired frame rate. Multiple results of the edge collapsing process are presented in this paper. Finally, the fixed rate interactivity during display is illustrated.
