本文研究了三点透视的图解理论和画法.根据中心投影、正投影原理和规律,运用旋转重合的基本作图法,论证出一种绘制三点透视的新方法——双向重合法.它与通常采用的视线迹点法、基线三角形法、量点法、交点法等相比较,有三个特点:1.理论简单、概念清晰、容易理解;2.作图准确,简便、实用:3.无需运用任何灭点和辅助灭点,作图占用板面较小.
This paper studies the three-point perspective graph theory and painting method.According to the principle of central projection and orthographic projection, we use the basic mapping method of rotation coincidence to demonstrate a new method of three-point perspective Compared with the commonly used sight trace method, baseline triangle method, volume point method, intersection method, etc., there are three characteristics: 1. The theory is simple and the concept is clear and easy to understand; 2. The drawing is accurate, simple and practical. No need to use any vanishing point and auxiliary vanishing point, drawing occupy a smaller board.
