摘要
针对三维有限元模型不规则数据场的特点 ,在直接体绘制算法的基础上 ,提出了一种基于scan buffer、适合多种有限元单元类型的算法 ,讨论了数据场到密度场不同的映射函数对绘制效果的影响 。
In accordance with characteristics of 3D finite element irregular data field, a direct volume rendering algorithm that is based on scan\|buffer and particularly suitable to multiple types of finite elements is proposed. The influence of functions mapping data field to density field on the image result is discussed, and several mapping models available to finite element data field are proposed.
