2. Randomly assign 1 of 9 colors to each of the selected monsters.
```

[0.95, 0.22, 0.1]
[0.1, 0.93, 0.22]
[0.1, 0.21, 0.88]
[0.99, 0.62, 0.33]
[0.33, 0.63, 0.99]
[0.62, 0.33, 0.99]
[0.33, 0.58, 0.27]
[0.87, 0.21, 0.77]
[0.11, 0.91, 0.89]
```

3. Randomly assign 1 of 5 rotations to each of the selected monsters.
```
Rotations (y-axis):
0
90
45
-45
-90
```

6. Randomly select 1 of 3 light positions.
```
Light positions (xyz):
[1.0, 0.2, 1.0]
[-1.0, 1.0, 1.0]
[-1.0, 2.0, -3.0]
```

7. Randomly select a light or dark environment.

8. Render the scene using OpenGL and save the frame to a PNG.

9. Compile raw PNGs into Apache Parquet files.
