摘要：

The Hybrid Octree (HO) is a new approach to deal with hybrid scenes, (i.e. scenes composed of surface and volume data). The HO codes into a single model a compressed approximation of an isosurface extracted from a volume dataset and a compressed representation of the scalar data. The HO definition and its construction algorithm are provided in the paper. We also describe the capabilities of the HO to efficiently manipulate surface and volume data independently and its facilities to composite and visualize surface and volume data using texture hardware. Special emphasis is given to the HO facilities to support multiresolution. Some examples are presented and the goodness of the model is discussed. (C) 2004 Published by Elsevier B.V.
