Detailed Description

Parameters for cloth simulator, as described in [BarWit98].

The stretch, shear, and bend parameters control the strength of the associated internal forces. For example, a higher _k_stretch value makes the internal stretch forces stronger, and hence makes the cloth harder to stretch. The bend force can be controlled independently in u and v. Generally, stretch forces should be very, very strong, and bend forces should be very weak.

The damp parameter controls the strength of damping forces. A higher damping value will make the cloth come to rest quicker, while a lower value will allow it to oscillate back and forth before coming to rest.

The b_u and b_v values allow the client to force stretch/compression of the cloth. They're not very useful at present; they should really be spatially varying to be useful.

The g parameter is the constant for acceleration due to gravity, by default 9.81 m/s^2.
