在“透视学”这门美术专业基础理论学科的教研实践活动中,我发现几乎所有的线性透视图法中有关消失线段的灭点都遵循“任何消失线段的灭点,都是从视点引一条实际上与这一线段平行的视线到画面的交点”这一规律,我称之为“灭点定理”。那么“灭点定理”是否成立?它在线性透视图法中的地位如何?“灭点定理”的确立在线性透视图法中关于确定消失点的作用是显而易见的,这是因为两条与画面成角且平行的线段,其消失规律一定是向画面上同 In the teaching and research practice of “Perspective”, a basic discipline of art major, I found that almost all of the vanishing line segments in the linear perspective method follow the “vanishing point of any vanishing line segment, which leads from the point of view In fact, this line of sight parallel to the line of sight to the intersection of the picture, ”the law, I call it“ vanishing point theorem. ” Then whether the “vanishing point theorem” is established and what is its position in the linear perspective method? The establishment of vanishing point theorem The effect of determining the vanishing point in the linear perspective method is obvious because the two terms Angular and parallel lines, the disappearance of the law must be the same screen
