位置関係を丁寧に説明する 位置関係と 空間認識のモード切替え さえ 意識化できれば 単純トリックが なんであるか わかる

If we meticulously describe the spatial relationships and even achieve a mode switch in spatial perception, becoming conscious of the positional aspects, we can understand what any simple trick entails.

This illustration represents the existence of four elements in a three-dimensional space: the sun, the left building, the right building, and the camera eye.

It is a top-down, two-dimensional diagram providing an overview.

The two buildings and the camera eye, represented by three points, imply a finite-sized triangle serving as a boundary in three-dimensional space to partition it into two regions.

If four points in three-dimensional coordinate space do not lie in the same plane, they form a tetrahedron. The tetrahedron divides the three-dimensional coordinate space into two regions: the interior and exterior spaces.

If we divide the three-dimensional coordinate space on the xy plane where z = 0, both regions Z > 0 and Z < 0 seem to extend infinitely in size.

If we divide the three-dimensional coordinate space into a tetrahedron, a cube, and a sphere, the internal space appears to have a finite size in each case.

Sun, the left building, the right building, and the camera eye are in a state of zero relative velocity.

Consider the ray of light from the sun to the camera eye as a line segment here. The straight line containing this segment is aligned with the x-axis.

At first, let's consider it roughly. The sun emits a ray at t=0, and the camera eye interacts with the ray at t=1. This is the diagram we are working with.
