甲、几何学基础绘画科学从点开始,其次是线,第三是面,第四是为许多面覆盖着的物体。一切物体的表现只能是这样。因为事实上,绘画不能超越面;正是凭它的面,任何可见物的实体才得以表现出来。点是没有中心的。它也没有长、宽、厚。线是点的运动产生的一定长度,它的两端是点。它既没有宽也没有厚。而是一条线的横运动造成的 A, basic geometry of science from the point of painting, followed by the line, the third is the surface, the fourth is covered with many objects. The performance of all objects can only be like this. Because, in fact, painting can not transcend the face; it is by its face that the entity of any visible thing can be manifested. There is no center at all It is also not long, wide, thick. The line is a point produced by a certain length of movement, its ends are points. It is neither wide nor thick. But a horizontal movement caused by a line
