Fields
impulse: N
The impulse applied by this constraint.
r: N
The scaling parameter of the SOR-prox method.
rhs: N
The target velocity change this constraint must apply.
impulse_id: Id
The index of the impulse used for its storage in an impuse cache.
assembly_id1: usize
The assembly index of the first body.
assembly_id2: usize
The assembly index of the second body.
j_id1: usize
Index of the first entry of the jacobian of the constraint affecting the first body.
j_id2: usize
Index of the first entry of the constraint jacobian multiplied by the inverse mass of the second body.
wj_id1: usize
Index of the first entry of the constraint jacobian multiplied by the inverse mass of the first body.
wj_id2: usize
Index of the first entry of the constraint jacobian multiplied by the inverse mass of the second body.
ndofs1: usize
Number of degree of freedom of the first body.
ndofs2: usize
Number of degree of freedom of the second body.

Checks if self
is actually part of its subset T
(and can be converted to it).
Use with care! Same as self.to_subset
but without any property checks. Always succeeds.

to the equivalent element of its superset.
