不容忽视的透视规律---论关于立方体的焦点透视关系

焦点透视是研究物体近大远小规律的科学.立方体在绝对平行的情况下,无法构成有深度的可视面,所以它在空间维度中仍处于二维平面状态,构不成三维空间的立体关系.当视点位置不变,将立方体作任何方向的移动,所产生的空间透视关系微妙而复杂.1995年高等教育出版社出版的<美术技法理论>第39页有关立方体平行透视的概念和图示有待进一步商榷.

Perspective Laws Not Allowed To Be Ignored Focal Perspective Relations of Cubes

The focal perspective is a science that studies the law that the object is big when near and small when far. In the absolute parallel condition, the cube cant constitute a visual surface with depth, so it is still in the two-dimensional plane state in space dimensions and cant constitute the stereoscopic relation in three-dimensional space. When the viewpoint is in an unchangeable position, and the cube is moved in any direction, the space perspective relation produced isa delicate and complex. The concept and graphical representations about the parallel perspectivity of cubes on page 39 in Theory of Line Arts Techniques and Skills (Perspectivism/Dissection) published by Higher Education Press in 1995 are pending further discuss.
