Contour drawing mirror image positioning amplifier

Abstract

The invention discloses a contour drawing mirror image positioning amplifier, which is characterized in that a mirror image reflector capable of moving parallel to a drawing board is arranged in front of the drawing board, and an isosceles triangle amplifying ruler and a sight distance rod are arranged in front of the mirror image reflector; the isosceles triangle amplifying ruler is installed on a horizontal sliding rod below the drawing board through a vertical connecting rod, and the horizontal sliding rod is externally provided with the sight distance rod. The contour drawing mirror image positioning amplifier adopts the mirror image reflector and the isosceles triangle amplifying ruler to carry out measurement and amplification on a mirror image directly, so that a drawing person is enabled to draw the shape contour of a scene or a building accurately according to a self determined proportion, and an error in the shape contour brought about by visual perception and estimation is avoided. Meanwhile, the time spent on contour drawing is further saved because of direct measurement and amplification without modification, thereby being capable of playing a good role for realistic drawing persons. The contour drawing mirror image positioning amplifier disclosed by the invention is scientific and reasonable in design, convenient and accurate in use, and applicable to contour positioning and amplifying for sketching, pencil sketching, color sketching of urban architecture scenery.

Description

technical field [0001] The invention belongs to drawing tools, in particular to a mirror positioning amplifier for contour drawing. Background technique [0002] Sketching, sketching, and color sketching are usually divided into two steps: first, the painter uses pencil lines to accurately draw the outline of the drawn body (the length, width, and height of the large body and partial body) on the drawing paper; then, On the basis of accurate outlines, black, white, and gray tones are used to apply light and shade to express the three-dimensional sense of space, light, and texture of the body to complete the painting. There are also forms of pure line or a combination of line and surface. [0003] Urban architecture is the painting theme of urban architectural landscape lovers. Although the architecture is complex, it is mostly composed of basic cubes and spheres (especially cubes). Therefore, most of its contour lines are vertical lines, horizontal lines, oblique lines and ...

AI Technical Summary

Problems solved by technology

[0004] It can be seen that in daily painting (sketching, sketching, color sketching), it is difficult to accurately draw the outline (length, width, height, structure, proportion, perspective) of the object in accordance with the proportion determined by the painter
