The shortcoming of morphological edge enhancement algorithm has been discussed. Based on that, an adaptive edge width reduction enhancement fuzzy algorithm is presented.

针对形态边缘减宽增强算法的不足，提出了一种自适应模糊边缘减宽增强算法。

As attributes cannot be set dynamically (edge width, face color, etc), all edges and faces look the same, so perspective can be confusing, especially in larger polyhedra.

由于属性不能设置动态(边缘宽度，外观颜色等)，所有的边缘和神情一样，因此观点都比较混乱，特别是在大型多面体。

Visitors can see the falls from many vantage points: above from a helicopter or microlight fixed wing plane, at eye level walking across the Knife Edge Bridge that spans the width of the falls on the Zambian side, or from below on a hike.
