This is UV, we grow a lot of UV If we grow a lot of UV, it will look like a wall When we open it, we can see what we have created We have created a wall around this triangle This is a representation of the area around this model And this is the UV for its length Its length is the height of this triangle This is the height of this triangle This model is more clear This model is used for standing cockroaches We usually see cockroaches lying down They don't usually stand So we draw them to stand But when we draw them to lie down This is also a clear model to make it easier for us to imagine When it is formed, it will look like a cockroach's bottom We don't want it to look like a cockroach's bottom So we draw it to look like a cockroach's bottom We draw it to look like a cockroach's bottom And we open it to make it easier for us to imagine It's like a box This box can be used to draw a circle or something In our drawings Let me flip it We can draw a circle or something When we draw it, we need to add a meter to add some holes But in our drawing, we don't have to If you want to make an octagon, you need to add some holes Then we can draw it It will be easier to imagine the space We can even open it up and put a stick in it to see what it looks like when we pull it. Sometimes we can't tell what we're pulling, so we put a stick in it to see what it looks like when we pull it. Thank you, Mr. Director. This is the result of our collaboration.
