摘要
针对规则体数据的特点,提出了一种介于直接体绘制和面绘制之间的切片法来实现其可视化,用双线性插值的方法获取切割面上的属性值,并用颜色编码来表示属性值。探讨了三维小波算法在规则体可视化中的应用,给出了用三维小波压缩规则体数据的一般方法。
In allusion to the feature of regular datasets, this paper presents a method named ＂slicing＂ to render those 3D regular datasets. Slice is a method which compromises of volume rendering and surface rendering. It can obtain the attribute data on the slice by bilinear interpolation and represent those attributes by coding color. It introduces the regular datasets compress method based on 3D wavelet and discusses the theory of this method.
