[−][src]Struct nphysics3d::solver::ConstraintGeometry
Logical information of the geometry of a constraint.
Fields
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 jacobian of the constraint affecting 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.
r: N
Scaling parameter of the SOR-prox method.
Methods
impl<N: RealField> ConstraintGeometry<N>
[src]
pub fn new() -> Self
[src]
Create a costraint geometry initialized to zero.
pub fn is_ground_constraint(&self) -> bool
[src]
Return true
if this constraint involve a body with zero degrees of freedom.
