Stupid polyhedron project. The only thing I can't find is WTF IS SPACE TESSELLATION?? I get what tessellation is, it's when a bunch off plane figures that align so that there are no gaps or over laps. But we have to define tessellation and what "space tessellation" is. Does anyone have a clue what the hell that means? :(

EDIT: I looked again, and apparently I just have to define tessellation and say whether it is plane tessellation or space tessellation. Now I can kind of assume that space tessellation just means that it is tessellation of polygons on a 3D surface--am I right?
