How to use:

Currently supports Catmull-Clark, Doo-Sabin, and Midedge subdivisions

usage: python3 subdivide_animate.py [-h] [-a A] [-d D] [-v V] mesh_file

example: python3 subdivide_animate.py -a 1 -d 2 -v cube_animation.mp4 data/cube.off

positional arguments:

mesh_file   an .off or .obj mesh file to subdivide

optional arguments:

-h, --help  show this help message and exit

-a [1, 2, 3]     subdivision algorithm to visualize

                    1: Catmull-Clark

                    2: Doo-Sabin

                    3: Midedge
              
-d D        number of subdivisions to animate

-v V        video file to output animation to
