A contact manifold between two shapes.

A contact manifold describes a set of contacts between two shapes. All the contact part of the same contact manifold share the same contact normal and contact kinematics.

Fields

points: ArrayVec<TrackedContact<ContactData>, 2>

The contacts points.

local_n1: Vector<Real>

The contact normal of all the contacts of this manifold, expressed in the local space of the first shape.

local_n2: Vector<Real>

The contact normal of all the contacts of this manifold, expressed in the local space of the second shape.

subshape1: u32

The first subshape involved in this contact manifold.

This is zero if the first shape is not a composite shape.

subshape2: u32

The second subshape involved in this contact manifold.

This is zero if the second shape is not a composite shape.

subshape_pos1: Option<Isometry<Real>>

If the first shape involved is a composite shape, this contains the position of its subshape involved in this contact.

subshape_pos2: Option<Isometry<Real>>

If the second shape involved is a composite shape, this contains the position of its subshape involved in this contact.

data: ManifoldData

Additional tracked data associated to this contact manifold.

Implementations

impl<ManifoldData, ContactData: Default + Copy> ContactManifold<ManifoldData, ContactData>
