“点、线、面”认识淡

Medhod of Understanding Point, Line and Surface

点只能在相对状态之中去认识和理解，有如下几个影响因素：视角、对比、印象。理解、联想。线的形成有三种形式：一种是面与面交界处形成的线；另一种是面的轮廓线；第三种是二维空间中独立存在的线。面的范围有两个概念：（1）二维空间的范围，由轮廓线决定；（2）三维空间的范围，如弧面、曲面等占有三维空间的面，由二维空间的面加上它向三维空间起伏的量决定。材质和纹理是构成面的特征的重要因素。

Point can only be known and understood in relative condition ,it is influenced by the following factors:1.angle of view;2.contrast;3.imperession;4.apprehension.5.association .Line is formed from three forms:One is the demarcation line of two faces. Another is the face's contour line.The third is the independent line in the two -dimensional space. There are two concepts of range of surfaces-range of two-dimensional space and range of three-dimensional space. Surfaces that have three dimensional space. for instance, Cambered suface, curred surface and so on, are defermined by range of two -dimensional space and their quantity undulating to the third.Qualities and veins of materials are very important factors that constitute the features of sureace.
