Lock Relative Transform When on, the relative transform between the child
and parent constraint spaces is locked: If you move either space in the viewport,
the other space moves along with it.
Strength Governs the size of the impulse the dashpot will apply to each
attached body, taking into account the difference in their relative offset
rotations (Child Space and Parent Space). The strength value is mass dependent
– for example, a strength value of 10 will generate a different behavior when
connecting two 5 kg bodies than when connecting two 50 kg bodies. Values
greater than or equal to 0.0 are valid for this property. Default=1.0.
Damping This value affects how quickly the oscillation of the angular dashpot
settles down. It governs the impulse applied to the connected bodies due to
their relative angular velocities. Valid damping values are those greater than
or equal to 0. Default=0.1.
TIP Typically, a damping value of 1/10th of the stiffness yields good results.
Allow Interpenetration When on, collisions are disabled between the
dashpot’s objects: During the simulation, they can pass through each other.
Default=off
Disabled When on, the dashpot is not added to the simulation.
Reset Default Values Click this to set Strength, Damping, and Disabled to
their respective default values.
Cooperative Constraints
Cooperative constraints are more stable than
simple constraints on page 3930,
but can be more computationally expensive to simulate. For a cooperative
constraint to take part in the simulation, you first need to add it to a Constraint
Solver
on page 3945. The solver acts as a container for the cooperative constraint
in a particular Rigid Body Collection, and performs all the calculations
necessary for the constraints to work together.
The following constraint types are cooperative constraints:
■
Hinge on page 3969
■ Point-Point constraint on page 3975
■ Point-Path constraint on page 3995
■ Car-Wheel constraint on page 3988
