Expand description
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: Vec<TrackedContact<ContactData>>
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.

&mut self,
pos12: &Isometry<Real>,
angle_dot_threshold: Real,
dist_sq_threshold: Real
) -> bool
pub fn try_update_contacts_eps( &mut self, pos12: &Isometry<Real>, angle_dot_threshold: Real, dist_sq_threshold: Real ) -> bool
Attempts to use spatial coherence to update contacts points, using user-defined tolerances.
sourcepub fn match_contacts(&mut self, old_contacts: &[TrackedContact<ContactData>])
pub fn match_contacts(&mut self, old_contacts: &[TrackedContact<ContactData>])
Copy data associated to contacts from old_contacts
to the new contacts in self
based on matching their feature-ids.

&mut self,
old_contacts: &[TrackedContact<ContactData>],
dist_threshold: Real

to the new contacts in self
based on matching the contact positions.
sourcepub fn find_deepest_contact(&self) -> Option<&TrackedContact<ContactData>>
pub fn find_deepest_contact(&self) -> Option<&TrackedContact<ContactData>>
Returns the contact with the smallest distance (i.e. the largest penetration depth).
