./draco_encoder -i testdata/bun_zipper.ply -o out.drc
./draco_encoder -i testdata/bun_zipper.ply -o out.drc -qp 14
//will quantize the positions to 14 bits (default for the position coordinates).

./draco_encoder -i testdata/bun_zipper.ply -o out.drc -cl 8
//In general, the highest setting, 10, will have the most compression but worst decompression speed. 0 will have the least compression, but best decompression speed. The default setting is 5.
