How to do trigonometric interpolation

If you are a fan of triangle intervention, you can have a look at the 32-hand-made triangle claws. I went to a lot of forums and saw that I was asking for tutorials or something. Now, at 32, I will tell you about the tutorial of triangular minions, so that everyone can understand how triangular minions are inserted and folded, not to mention watching the tutorial.

Tools/raw materials

Yellow, black and blue triangles are inserted on the lids of two water bottles, and white latex paper and oil pen are used.

Body parts:

1/9 Step by step reading

First take out two blue triangular plugs, one black triangular plug, insert the black triangular plug backwards, and then insert two blue triangular plugs.

2/9

Always insert a circle according to the method just now, as shown in the figure.

Then connect the circles.

3/9

At the periphery of the circle, it is always interleaved by normal cross interleaving.

4/9

Turn the circle upside down and lift the sides.

5/9

Just find a direction, insert six blue triangles in front, five triangles in the back, and yellow triangles in the others, as shown in figure 1.

Insert five blue ones on the six on the second floor, four triangles on the corresponding back five, and yellow triangles on the others.

Always insert and fold five layers according to the method of 5 6 5 6 (the jumpsuit is shaped here)

6/9

What we need now is a tape of a jumpsuit. First, insert 1 blue triangle on one side of six, insert four triangles on the back, and insert yellow triangles on others, as shown in figure 1 2 (the back is made of blue).

Go to the next floor and start inserting one on each side and unfold the belt.

7/9

Until the front and rear shoulder straps look at the side, leave room to insert four blue triangles, as shown in figure 1.

Then insert four blue triangles on it, the same on the other side, and yellow triangles everywhere else.

8/9

At first, there is no need to change color, and the yellow triangles cross normally until the top opening shrinks inward a little.

9/9

The beginning here is the capping step, so pay attention here.

First, squeeze the opening to the middle by hand. Because the density of the triangle plug just squeezed is very close, now insert 3 small corners with 1 triangle, as shown in the figure.

According to this method, the hole that has been inserted in the middle can't be seen, and finally Minions's body is completed
