30 Texture-based Hybrid Visualízations

Abstract

ln this paper the visualization of hybrid scenes that contain volume data anda fitted extracted surface is addressed. The proposed algorithm is based on a integrated octree-based representation: the "Hybrid Octree ". The Hybrid Octree allows to obtain multiresolution representation of the volume data and it also maintains a decimated surjace codification. The proposed visualization approach uses 3D-textures for the visualization of the volume data and integrates the surface polygons using the information represented in the octree structure. The main characteristics of the method are: its capabilities to perform multiresolution hybrid visualizations and its efficient use of texture memory space.
