= Cloth simulations =

== Overview ==

The cloth solver simulates deformable surfaces.
A variety of surface types can be simulated, including
fabric, rubber, and metal.
Any piece of SOP geometry can be turned into a cloth object,
no triangulation is required.

See [relationships|relationships] for how to make cloth interact with other objects.

== Shelf tools ==

The [Cloth shelf tab|/shelf/cloth] contains tools for creating cloth sheets. You can also use the [forces|forces] on the [Drive simulation shelf tab|/shelf/drivesimulation] to affect the cloth.

The [Cloth Constraint tool|/shelf/clothpinconstraint] lets you pin a point on a cloth object to a point in space or another object.

== Important nodes ==

- [Cloth object|Node:dop/clothobject] - imports geometry to use as a cloth sheet.
- [Cloth solver|Node:dop/clothsolver]
- [Cloth constraint|Node:dop/sbdpinconstraint]

== Useful cloth object parameters ==

Stretch stiffness:
    The resistance to stretching. Higher numbers mean the cloth is harder to stretch.

Shear:
    Resistance to shearing (forces along the plane of the cloth; if you stretched a square into a parallelogram that force would be shearing). This affects creasing where cloth is draped over a corner, as in a tablecloth on a table.
 
Bend stiffness:
    Increase this to make the cloth smoother/more resistant to wrinkles.
