Struct nphysics2d::object::MassConstraintSystem [−][src]
Expand description
A deformable surface using a mass-LengthConstraint model with triangular elements.
Implementations
Builds a mass-spring system from a polyline.
Retrieves a reference to the user-defined user-data attached to this object.
Retrieves a mutable reference to the user-defined user-data attached to this object.
Sets the user-defined data attached to this object.
Replace by None
the user-defined data attached to this object and returns the old value.
Add one constraint to this mass-constraint system.
Generate additional constraints between nodes that are transitively neighbors.
Given three nodes a, b, c
, if a constraint exists between a
and b
, and between b
and c
,
then a constraint between a
and c
is created if it does not already exists.
The coefficient used for warm-starting the resolution of internal constraints of this soft body (default: 0.5).
The coefficient used for warm-starting the resolution of internal constraints of this soft body (default: 0.5).
Restrict the specified node acceleration to always be zero so it can be controlled manually by the user at the velocity level.
Mark all nodes as non-kinematic.
Sets the plastic properties of this mass-constraint system.
