Making method of 3d holographic projection (making 3d holographic projection by hand at home)

Tutorial of making 3D holographic projection;

Tools:

I. Mobile phone or tablet computer

Two. Ruler, knife, compass, glue.

Material: ordinary transparent plastic film or special projection film, a draft paper.

Note: The top angle of an isosceles triangle is 70.5 degrees, and the bottom of quot is equal to the width of the screen. Quot is not standard, as long as it is not less than the width of the video being played!

Production process:

Step 1: Determine the width of the screen and measure it with a ruler.

Step 2: Draw a circle on the draft paper, with the waist length of the isosceles triangle as the radius, any point on the circle as the center and the radius as the bottom of the isosceles triangle.

Step 3: Cover the drawn circle with plastic film and make a hole at the vertex of the triangle as a mark. Cut four connected isosceles triangles with a knife.

Step 4: Connect the two sides of the edge with glue or tape to form a pyramid.

Actually, look directly at the picture below. You need not be so careful. You can get four isosceles trapezoid. This one is only based on feeling, but the best imaging effect can be obtained by ensuring that the last four images are refracted to the center. Operation: Download the 3D holographic video to the mobile phone and open it. Place the mobile phone horizontally on the pyramid, with the center of the screen corresponding to the spire and as close as possible. Look straight at the side of the pyramid horizontally and you will find unexpected results!

Make it look like a four-sided funnel,

3D resources can be directly searched online and then played.
