文字从诞生开始便具有了点画这样的视觉元素。

Since its natal day , characters possess the visual elements such as dots and strokes .

虚位移法规定阴影面积之和等于点画面积之和。

The virtual displacement method specifies that the sum of the shaded areas is equal to the sum of the stippled areas .

点画的粗细、轻重、长短、高低的不同，是使文字呈现不同的空间结构。

Stippling of the thickness , weight , length , height difference , Is to present a different spatial structure of the text .

包括执笔、运笔、点画、结构、布局（分布、行次、章法）等内容。

Including the pen , brush , stippling , structure , distribution ( distribution , transportation times , the rules ) and so on .

He started with a single dot . It took the artist hours to finish his picture , and afterwards he collapsed back into bed .

这一点是指其身体上的发光斑或发光点。减淡工具：用于增加高光点，给局部加光和点画。

This may show as luminescent blotches or spots on the body . Dodge : Used for adding highlights , lightening areas and for stippling .

草书作为有稳定点画系统和固定组织结构的书体，有其独有的生成机制：草化&省减、连带和概括。

Cursive as a stable point system and fixed structure of style , has its unique formation mechanism : Grass & Province , reducing joint and grass .

从物理学的角度来分析，墨汁与纸的摩擦，可把笔力注入到点画线条之中，达到力透纸背、入木三分的效果。

From a physical perspective , the friction of ink and paper , puts the stroke strength into the dots and lines , achieving forceful and penetrating effect .

书法中也特别强调虚实关系，就是研究点画之间的空白处理。

It is also stressed in calligraphy that the relationship of nothingness and essence is used to study how to deal with the blanks between points and paintings .

但这种线条并非任一自然线段，而是指摆脱了图画性质，变成适合文字点画书写的线条。

However , this line is not any of the natural line , but to get rid of the picture character , into a suitable text written in dotted lines .

点画及其多样化属于非真实感图像渲染中的艺术风格渲染，艺术风格渲染更多是对现有艺术形式和自然媒体的计算机模拟和实现，来帮助人们更便利地创造艺术化图像。

Artistic rendering pursues the personal and artistic presentation of graphics , which mostly imitates the present artistic forms and natural media to help create artistic graphics and images more conveniently .
