本文根据平行分割法分割水平变线透视的作图原理和利用光点、足点求作建筑透视图中阴影的作图规律,推导出了一种绘制建筑两点透视图中阴影的新办法——平行分割法。它与通常的光截面法等比较,有如下特点:省略了光点、足点、缩小了作图板面;理论简单、易理解;作图准确、实用。
In this paper, according to the principle of dividing the horizontal line perspective by the parallel segmentation method and using the light point, the foot point to make the drawing rule of the shadow in the architectural perspective, a new method to draw the shadow in the two perspectives of the building is deduced— - Parallel division method. Compared with the ordinary light section method, it has the following characteristics: the light spot, the foot point, and the drawing board surface are reduced; the theory is simple and easy to understand; the drawing is accurate and practical.
