【摘要】 提出一种新的三维等值线充填方法,使用本方法不仅可以绘制单个数据的三维带颜色充填等值线,而且可以在一个空间曲面上叠合绘制同一区域代表不同物理属性的数据的等值线。看上去外层数据带充填颜色的等值线就像一个可任意拉伸的半透明的覆盖面铺在下层曲面上一样。从而能够直观地反应出不同物理量之间的关系。因为在同一区域不同数据的等值线可能会出现交叉、重叠等复杂情况,所以充填叠合以后等值线之间的颜色的方法也相应的要考虑更多的因素。本方法在规则网格数据上实现,但其思想也可应用于三角网方法。更多还原

【Abstract】 A new method is proposed to fill the 3D contour field.It can be used not only to render the filled 3D contour of one datum,but also to render the three-dimensional overlapped contour of various data in the same measuring zone that represent different physical properties on one surface.It seems that the filled contour field of outer layer data is an infinitely stretched semitransparent coverage that is paved on the existing surface.This can intuitively reflect the relationship between various physical data.As the complex phenomenon will occur caused by the intersection or superposition of contours of different data,more factors should be considered in filling color of the contour field.This technique is realized on the basis of regular grid data,and its principle can be used in Triangle Mesh.更多还原
