摘 要: 在手工绘制两点透视图时,都会碰到图幅过大造成灭点与视点落在图板之外而难以操作的难题。采用一个与视灭三角形相似的小三角形作为绘图辅助,同时结合量点法中的分量点概念进行作图,就可以很好地解决这个难题,而且能更加快速准确地绘制两点透视图。 When drawing two-point perspective manually, the problem is always occurred that vision point and vanishing point is out of the drawing board. This paper introduces the method of using a small triangle which is similar to the vision-vanishing point triangle to solve the problem, so that making perspective drawing more rapidly and precisely.
