Optical illusion 3D teaching material "Three-sided vision"

Abstract

To provide a visual teaching material that improves the drawing accuracy and visual effect of a constituent pattern in a formative teaching material for experientially learning about optical illusion three-dimensional images that differ depending on the viewpoint. [Solution] This is a visual aid in which a three-sided cubic structure is assembled from cardboard, and a grid (guideline) is printed on each side of the development diagram. By using this grid as a reference for drawing the image, the user can accurately create an optical illusion with a limited viewpoint. In addition, the development diagram is designed to fit on industrial standard paper, making it easy to mass-distribute and produce in educational settings.

Description

[Technical Field]

[0001] This invention relates to visual teaching materials used in basic art education, and in particular to "three-sided viewing" teaching materials that utilize optical illusions in which the impression of a shape changes depending on the viewpoint. [Background technology]

[0002] Conventional three-dimensional teaching materials involve assembling unfolded diagrams to learn shapes, but there are few teaching materials with structures that create an optical illusion of three-dimensionality from a specific viewpoint, and it is difficult to control the visual effect after assembly at the design stage. Summary of the Invention [Problem to be solved by the invention]

[0003] Conventional three-dimensional teaching materials have been limited to designs based on development drawings, and there have been few teaching materials that utilize the optical illusion effect caused by viewpoints. [Means for solving the problem]

[0004] This device is characterized by the fact that a grid (guideline) is applied to the unfolded drawing in advance, and by maximizing the optical illusion effect, different visual information is given to the three sides. [Effects of the Invention]

[0005] By using this teaching material, students can intuitively learn to grasp three-dimensional objects and understand their structure from different viewpoints. [Brief explanation of the drawings]

[0006] [Figure 1] Exploded view [Figure 2] Completed form (3D) [Figure 3] Perspective illusions

[0007] The development diagram is designed to fit on cardboard. The unfolded view has grid lines drawn on it, which act as a guide for drawing each side. · Fold the unfolded diagram into mountain and valley folds to form a trihedron.

Claims

[Claim 1] This visual aid has a trihedral structure, with multiple reference lines (grids) arranged on a flat unfolded view, and by folding and assembling the unfolded view, a structure is formed in which three sides can be seen simultaneously, causing a viewpoint-dependent visual illusion.
