体积和多边形模型的混合渲染是可视化系统的一个有趣功能，因为它可以帮助用户更好地理解体积的内部结构与拟合曲面以及外表面之间的关系。现有的参考书目大多集中于正确、深入地整合这两类信息的问题。本文提出的渲染方法是建立在这些先前结果的基础上的。它旨在解决一个不同的问题：如何有效地访问混合模型的选定信息。我们建议构建一个决策树（渲染决策树），它与模型的辅助游程表示一起避免在模型遍历期间访问未选择的表面和内部区域。
Hybrid rendering of volume and polygonal model is an interesting feature of visualization systems, since it helps users to better understand the relationships between internal structures of the volume and fitted surfaces as well as external surfaces. Most of the existing bibliography focuses at the problem of correctly integrating in depth both types of information. The rendering method proposed in this paper is built on these previous results. It is aimed at solving a different problem: how to efficiently access to selected information of a hybrid model. We propose to construct a decision tree (the Rendering Decision Tree), which together with an auxiliary runlength representation of the model avoids visiting unselected surfaces and internal regions during a traversal of the model.
