Rubber sheet geometry noun a humorous name for topology.

Rubber sheet geometry exampl.

Topology branch of mathematics sometimes referred to as rubber sheet geometry in which two objects are considered equivalent if they can be continuously deformed into one another through such motions in space as bending twisting stretching and shrinking while disallowing tearing apart or gluing together parts. Generally most rubber materials fall under the rubber durometer scale of shore a. It provides simple fixed placement of windows where you specify the exact size and location of one window called the slave within another window called the master the placer also provides rubber sheet placement where you specify the size and location of the slave in terms of the dimensions of the master so that the slave changes size. Hence a square is topologically equivalent to a circle but different from a figure 8.

The placer is a geometry manager for tk. For example a square can be deformed into a circle without breaking it but a figure 8 cannot. Thus if you need a rubber or o ring durometer that feels like a running shoe sole review our rubber hardness chart below then pick shore 70a. A rubber durometer of shore 70a is the most commonly chosen material hardness for all applications.

Concept of topology rubber sheet geometry topology does not distinguish between a circle and a square but it does between a circle and a figure eight. A sheet of rubber especially one from which shapes can be cut or which is used to protect against water dirt etc.
