Technical Field

The invention relates to application of points on the same horizontal plane in perspective in modeling and painting, belonging to the field of art.

Background

In the past, when drawing a figure, a painter used visual observation and feeling to finish the figure and perspective of an object, but because of the different visual observation and feeling abilities of each person, the figure and perspective level of the drawn object are uneven, and the visual observation and feeling are difficult to express the perspective figure of the drawn object by language.

Disclosure of Invention

The point on the same horizontal plane is below the horizon line, near low and far high, and the point on the same horizontal plane is above the horizon line, near high and far low. The theory is used for guiding the drawing modeling, the drawing modeling is not completely finished by visual inspection and feeling, the perspective of the points on the same horizontal plane can be measured and judged according to the perspective rules of the distance of the points on the same horizontal plane, and a beginner can easily and accurately draw the modeling of an object after mastering the theoretical knowledge.

The technical scheme is as follows: the application of points on the same horizontal plane in perspective in modeling and painting is characterized in that: observing vertexes 1, 2, 3 and 4 … … N of cubic projection at a main viewing position, wherein a vertical line corresponding to N vertexes 1, 2, 3 and 4 … … N is A, B, C, D … … Z, the vertexes are arranged in alphabetical order, the included angles between the N vertexes 1, 2, 3 and 4 … … N and a horizontal plane on the same plane are calculated by taking an observer as a reference point, the size of the included angle between the N vertexes 1, 2, 3 and 4 … … N and the horizontal plane depends on the distance between a reference point and the observed N vertexes 1, 2, 3 and 4 … … N, the closer the distance between the observation point and the reference point is, the smaller the included angle between the vertex and the horizontal plane where the reference point is located is determined by the size of the included angle between the horizontal plane where the reference point is located and the observed N vertexes, the larger the included angle is reflected to a stereoscopic space, the horizontal plane is high in the low-low position relationship between the perspective point, and the size of the included angle between the horizontal plane where the reference point is located and the The most important rule.

Regarding vertexes 1, 2, 3 and 4 projected by a cube observed on a main view position, a vertical line corresponding to the four vertexes 1, 2, 3 and 4 is A, B, C, D, and the included angles between the four vertexes 1, 2, 3 and 4 and a horizontal plane on the same plane are A, B, C, D, wherein the size of the included angle between the four vertexes 1, 2, 3 and 4 and the horizontal plane where the reference point is located is determined by the distance between the reference point and the four vertexes 1, 2, 3 and 4 observed, and the closer the observation point is to the reference point, the smaller the included angle between the vertexes and the horizontal plane is, namely, the closer the vertex is, the higher the height is.

Regarding the four-side pyramid, the included angles between the four vertexes 1, 2, 3, 4 projected from the cube and the horizontal plane on the same plane are observed on the principal viewing position, and taking the observer as the reference point, the size of the included angle between the four vertexes 1, 2, 3, 4 and the horizontal plane of the horizontal plane where the reference point is located depends on the distance between the reference point and the four vertexes 1, 2, 3, 4 to be observed, and the closer the distance between the observation point and the reference point is, the smaller the included angle between the vertexes and the horizontal plane is, namely, the closer the distance is, the higher the distance is.

Regarding the six vertexes 1, 2, 3, 4, 5, 6 projected by observing the cube on the main viewing position of the hexagonal prism, the included angles between the six vertexes 1, 2, 3, 4, 5, 6 and the horizontal plane where the reference point is located on the same plane, taking the observer as the reference point, the included angles between the six vertexes 1, 2, 3, 4, 5, 6 and the horizontal plane depend on the distance between the reference point and the six vertexes 1, 2, 3, 4, 5, 6 observed, and the closer the observation point is to the reference point, the smaller the included angle between the vertexes and the horizontal plane where the reference point is located, namely, the closer the higher the vertex is, the lower the included angle is.

The perspective modeling drawing of other complex polyhedrons also conforms to the rule, namely the height is low, the height is high, and thus the polyhedrons are clear in level, strong in stereoscopic impression and clear at a glance.

Before, during drawing, the painter finishes the modeling and perspective of the object by visual observation and feeling, but because each person has different abilities in visual observation and feeling, the modeling and perspective level of the drawn object is uneven, the visual observation and feeling are difficult to express the perspective modeling of the drawn object by language, the point in the same horizontal plane is at the same sight line, is at the same height, and the point in the same horizontal plane is above the sight line and at the same height, so that the drawing modeling is guided by the theory, the drawing modeling is finished without completely depending on the visual observation and feeling, the perspective of the point in the same horizontal plane can be measured and judged by the perspective law of the distance and the proximity of the point in the same horizontal plane, and a beginner can easily and accurately draw the modeling of the object after mastering the theoretical knowledge, thereby being a theoretical basis guide and drawing a perspective view by the method, the perspective view is easily and freely drawn no matter how complex, how many points in space, and how complex the levels are.

The invention has the advantages.

1. The perspective positions of the points on the same horizontal plane can be measured and judged according to the perspective rules of the distance of the points on the same horizontal plane, and theoretical basis is provided.
