EPhysics: add soft body bending constraints API
This patch introduces the API ephysics_body_soft_body_bending_constraints_add used define how deformeable a soft body is supposed to be. Patch by: Leandro Dorileo <dorileo@profusion.mobi> SVN revision: 79592

|

|
* Add new bending constraints to some @p body.
|
||||||
|
*
|
||||||
|
* Bending constraints define how a soft body is to be deformeable. In fact a
|
||||||
|
* bending constraints represents a link between a soft body mesh triangle and
|
||||||
|
* other. The hardness property is used to define the bending constraint of
|
||||||
|
* those new links.
|
||||||
|
*
|
||||||
|
* By default EPhysics create a new soft body or cloth with a single bending
|
||||||
|
* constraint.
|
||||||
|
*
|
||||||
|
* @param body The body to add bending constraints to.
|
||||||
|
* @param number The number of bending constraints to be added, it must be
|
||||||
|
* greater than 0.

||||||
