摘要
本文提出了一种用于稀疏不规则数据集的体绘制方法。此方法使用建立于全局插值的随机过程插值函数,通过调节少数几个参数就可以改变模型的形状。不需任何体元(CELL)结构就可以直接获得光强的积分。因此,它节约了空间和时间开销,有较高的效率。
This paper proposes a new volume rendering approach for scattered volume data.This ap- proach uses a stochastic process model built by globally interpolating the sample data,which have acntinuous partial derivatives and whose shape can be change by adjusting a few parame- ters.Without any Cell structures,it obtains the intensity of light by direct integration.So it has higher efficiency and lower costing of space and time.
