摘要： 提出了一种新的密度云图像合成算法,用于表现3D数据场的分布。算法从视觉模型的计算入手,对图像合成中的基本图元—四面体进行遮蔽优先度排序,算法充分利用了数据场的三维连贯性,可用于三维规则及非规则数据场的可视化。

Abstract: We present an algorithm for compositing density clouds used to represent scalar fields on a 3D volume subdivided into tetrahedra.The algorithm starts with the calculation of cloud illumination model and then depth-sorts the tetrahedra used in the composidon.The algorithm takes advantage of area and volume coherences and can be used for visualizing 3D regular and irregular data fields.
