For any given resolution and object, this module returns a set of triangle strips representing the object at that resolution, that is, at the level of detail requested. These models use triangle strips to reduce storage usage and to speed up realistic rendering.

Inputs:\n
	- The module receives a file describing a multiresolution object.
	.

Outputs:\n
	- The module returns a strip set that represents the level of detail requested.
