视觉印象与实际形态永远存在着差异。严格地讲,在平面中绘制的任何图形都能够产生视错觉,甚至可以说正是为了造成视错觉。我们都有这样的经验:在纸上随意画一条线或点一个点,看它们像是与纸分离,浮在纸的上面。我们正是利用了视觉的这种错误,把文字书写在纸上,使阅读成为可能。又比如,在白纸上画一个黑色矩形,再在黑色矩形的中间画一个较小的白色圆形,会看做是白纸的前面放着一个挖了圆孔的矩形黑纸,从圆孔中透出了白色的背景。这种现象是大脑习惯性的对三维空间的理解模式造成了我们对视觉信息的主观判断。我们生活在一个三维的空间中,这个立体的世界造就了我们的视觉习惯、空间观念和思维方式。我们习惯于认同具有三维空间视觉效果的形态,因此总是习惯地把存在于二维空间中的形态主观地赋于它们三维空间的秩序,视它们为与背景分离并重叠的状态。造形艺术是把人的视觉作为研究的主体,把物形作为研究的客体,把心理效应作为这二者情态结构调节的结果。 描写现实生活的绘画正是为了适应人们的空间观念和视觉习惯,这使模拟三维空间的视觉效果成了写实主义绘画的灵魂。在平面中仿制立体世界的体积和纵深,也是视觉传达设计的重要表现手法。数百年来众多的科学家和艺术家为研究在平面中表现三维空间视觉?
There is always a difference between visual impression and actual form. Strictly speaking, any graphic drawn in a plane can produce optical illusions, and can even be said to cause illusion. We all have the experience of drawing a line or a point on a piece of paper and looking at it as if it were separated from the paper and floated on the paper. We took advantage of this error of vision, writing words on paper, making reading possible. For another example, draw a black rectangle on white paper, and draw a small white circle in the middle of a black rectangle, which will be seen as a rectangular black paper dug round the hole in front of the white paper. Out of the white background. This phenomenon is the brain’s habitual understanding of the three-dimensional space that has led to our subjective judgment of visual information. We live in a three-dimensional space that creates our visual habits, spatial concepts, and ways of thinking. We are accustomed to recognizing patterns that have the visual effect of three-dimensional space. Therefore, we always accustomed to subjectively assign the patterns existing in two-dimensional space to the order in their three-dimensional space and regard them as separate and overlapping states from the background. Shape art is the human body as the main body of the study, the figure as the object of study, the psychological effects as the result of the adjustment of the two modal structure. It is precisely to describe people’s space concept and visual habit to describe the painting in real life, which makes the visual effect of simulating three-dimensional space become the soul of realistic painting. The volume and depth of imitating the three-dimensional world in the plane are also important expressions of visual communication design. Hundreds of years of numerous scientists and artists to study the performance of three-dimensional visual in the plane?
