基于分块混合八叉树编码的海量体视化研究

Hybrid Blocking Octree-based Mass Volume Rendering

在介绍当前体数据的数据模型与绘制方法的基础上,使用混合八叉树进行体数据的描述,实现了对其自适应分块存储。并用体元投射和三维纹理映射方法分别实现了混合八叉树的体绘制与多分辨率绘制。实验结果表明,该文的算法较好地实现了基于混合八叉树结构的海量体数据的组织、存储和绘制。

Based on the introduction of common data models and rendering algorithms for volume data, this paper proposes a hybrid octree encoding to describe it. Self-adaptive blocking method is applied to store and manage mass volume data. Volume rendering and multi-resolution rendering for hybrid octree via cell projection and 3D-texture mapping are implemented. Experimental results show that the algorithms effectively solve storage, management and rendering for hybrid octree based mass volume data.
