Note: The iteration function has been added and can be iterated infinitely. The result of each iteration is a conditional iteration.

You only need to follow the "Drawing transform graph" to start iteration. To start iteration again, you need to follow the "Drawing transform graph", that is, the first transformation graph is our initial value. The iteration chart has no coordinate display.

Do not press "Enter iteration result as input". This is another function!

Points are automatically labeled as a, B, c, d... and transformation fig A', B ', C', d '...

The initial value of the transformation matrix is changed to rotate arcsin0.8 counterclockwise and the scaling factor is 1. You can also enter the Rotation Angle and scaling factor to construct the rotation matrix. When A11 = A22, A12 =-A12, the transform matrix is a rotation matrix. Otherwise, it cannot be called a rotation matrix, but an affine transformation.

1) enter the corresponding x and y values in the input box, and then press "Add new vertex" to enter a series of exact points;

Or: click "re-draw the original image" to create a series of inaccurate points;

2) Input transformation matrix;

3) Click "Draw transform graph" to obtain a matrix transformed graph;

4) The coordinates can be displayed or hidden in the graph;

You can also list coordinates on the left of the screen.

This download contains the compiled executable file and source code, which are written in VB6.0. I am unwilling to use VB6.0, because... Ah, this is obviously pirated. Most of the time, vc2008express is free and legal. My friend asked me to complete the software, but VB6.0 was the best guy. Use it ....
