立方体の九九をざっくり説明しました。

表記について、動画内で決めあぐねていますが
2/(6:4)や4/(6:4)がよいと思います。
下から見た場合には
(6:4)/2や(6:4)/4という感じにするのがいいかと。

風景デッサンの基本(ナツメ社)の
13ページに掲載した立方体の描き方の説明になります。
面の比率で表記するアイデアは
本の出版後に思いついたものなので
本の中では説明されていません。

how to draw a cube Cube multiplication table basics

0:01
yes
About the cube multiplication table
I would like to explain it briefly.
0:18
What is the cube multiplication table?
0:22
When you draw anything, you always try to balance it.
I wonder if I should make my face look like this.
0:30
Therefore, it is better to maintain balance when drawing a cube.
0:37
I want to draw it in this size
0:39
First, I thought I could visualize it.
0:43
in
This balances the overall size of the cube.
Take it.
0:48
for example
when writing hands
0:51
I'm going to draw a hand around here.
It's like there's a joint around here.
0:58
And here's my finger
That's what I thought
1:03
So my wrist is here
Think of it like it's attached.
1:05
Then, wouldn't it be okay to have a line to separate the quantities?
1:11
It might be good to have something like this as well.
1:15
Similarly, how far does this upper surface reach?
What does it mean to strike a balance like this?
1:20
This line is included because it's okay to have one.
1:26
that's why
I want to draw cubes of similar size.
When
If you do it like this, there will be less of the top surface.
1:35
If you do it like this, you can see a lot of the top surface.
That's what it means.
1:40
This way the top side will be more
I can see a lot
Is that what you mean?
1:47
There's also the question of whether it's on the right or the left.
If you can see this much of the top and it's in the middle
It feels like it's symmetrical.
2:00
in
I can see the top side at the same level.
If it's to the right of the center
Well,
I can see a lot of the left side
2:12
On the other hand, if it looks like this, you can see a lot of the right side.
But it is that.
Hmm...
Roughly drawn
2:19
for example
I wonder if something like this will happen.
2:26
That's about it.
If it is symmetrical
I wonder if it will turn out like this.
2:36
Well, that's it
Speaking of notation
2:50
for example
2:52
Hmmm
What should I do
2:55
I did it like this~
2:57
Suppose you do this
3:00
This amount and this amount
Like 6 to 4
Think about it.
3:09
So if you do this
