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.
