The activity of observing a distorted image using a circular mirror.
If you search for anamorphosis on the Internet, you will find many pictures.
Recently, it is also included in textbooks.
I thought it would be good for students to do their own activities.
I made an anamorphosis, so I made a program.
You can easily create your own distorted picture by running the anamorphic make program and output it for viewing.
Run the program, adjust the number of squares, and draw directly inside the right rectangle. I was thinking about how to use it. To make drawing easier, hold down the mouse in a blank area to draw a picture, and start holding it down in a colored cell to erase it.
You can also draw a picture using a paper layout, and if necessary, use a program to draw your own cool picture. If you capture the screen and print it out, you can observe it with a cylindrical mirror.
