# Projection Matrix Display
This software is intended to provide a way to check that a 3D projection matrix is valid.
To perform the test, place the matrix into a file called `proj`. Example:
```
1.0, 0.0, 0.0, 0.0
0.0, 1.0, 0.0, 0.0
0.0, 0.0, 1.0, 0.0
0.0, 0.0, 0.0, 1.0
```
(The above matrix will not work properly for a 3D projection but its format is correct)
If the matrix is correct, the display will show a 3D projection of the 42AI organization's logo.
