A little perspective means that due to the change of the relative position between the object and the picture, the contour lines of its length, width and height may or may not be parallel to the picture. The perspective drawn in this way is called point perspective In this case, the object has an elevation parallel to the picture in one direction, so it is also called frontal perspective.
If an object has two sets of main contours parallel to the picture, there will be no vanishing point in the perspective of these two sets of contours, but the third set of contours must be perpendicular to the picture, and its vanishing point is the center point.
2, two-point perspective
If an object has only one vertical contour parallel to the picture and the other two groups of horizontal main contours are inclined to the picture, two endpoints are formed on the picture, both of which are on the horizontal line of the eyes, so the perspective formed is called two-point perspective. It is precisely because in this case, the two vertical angles of the building are inclined to the screen, so it is also called angular perspective.
3, three-point perspective
Three-point perspective is a painting method, which is generally used for super high-rise buildings, overlooking or looking up. The third vanishing point must be perpendicular to the main line of sight of the picture and consistent with the bisector of the viewing angle.
Extended data:
(1) Multi-view
Chinese painting is good at expressing rich plots, while western painting pays attention to a single point of view (similar to photography) The rich perspective plot emphasized by Chinese painting can not be completed from a single angle. Therefore, Chinese painting is represented by multiple viewpoints (similar to the segmentation and reorganization of multiple lenses of a camera). Such as The Riverside Scene at Qingming Festival.
(2) high viewpoint
From a low point of view, mountains with "high mountains" are often painted in the distance and then connected by clouds. Show a feeling that people are higher than mountains. Chinese painting does not look up at close range to show mountains.
(3) Long sight distance
Chinese painting emphasizes that "there is a long way to go, and the things in the painting are required to conform to the normal proportion of things." Therefore, painters must use telephoto to express them.
Picasso's works break the basic law of perspective, showing all the visible and invisible front and back sides of an object in a two-dimensional space. To understand Picasso's paintings, we must first abandon perspective.
Generalized perspective appeared 30 thousand years ago. Before linear perspective appeared, there were many perspectives.
① Longitudinal perspective. Draw an object far from the observer on a plane on the object close to the observer.
② Oblique perspective. Objects far away from the observer extend upward along the oblique axis.
③ Overlapping method. The foreground object is above the background object.
(4) Near-large and Far-small method, drawing a distant object smaller than the near equivalent object.
⑤ Proximity method. The proximal portion is intentionally narrowed to prevent the distal portion from being blocked due to the normal perspective of the proximal portion.
⑥ Aerial perspective. The farther away the object is, the more blurred the image is; Or objects at a certain distance are blue, and the farther they are, the heavier the color, which can also be attributed to color perspective.
⑦ Color perspective method. Due to the air barrier, objects of the same color are bright when they are near and gray when they are far away.
