Abstract: | In this paper we present a new approach for interactive view-dependent rendering of large polygonal data sets which relies
on advanced features of modern graphics hardware. Our preprocessing algorithm starts by generating a simplified representation
of the input mesh. It then builds a multiresolution hierarchy for the simplified model. For each face in the hierarchy, it
generates and assigns a displacement map that resembles the original surface represented by that face. At runtime, the multiresolution
hierarchy is used to select a coarse view-dependent level-of-detail representation, which is sent to the graphics hardware.
The GPU then refines the coarse representation by replacing each face with a planar tile, which is elevated according to the
assigned displacement map. Our results show that our implementation achieves quality images at high frame rates. |
