# Test 1
This test requires a directory called `chunks` in the current working directory,
filled with mAABB file that follow the naming convention: `<string>,<int>,<int>`.
This test will create a directory called `chunk_models` containing `ply2` files.
The mAABB file format contains an arbitrary number of AABBs, with one line per each:
`<min-x> <min-y> <min-z> <max-x> <max-y> <max-z>`
This program should be ran via the command line with `java -jar`. It will tesselate each
file and save them in `ply2` format in the `chunk_models` directory. This will take a while.
