Struct parry2d::shape::PolygonalFeature

pub struct PolygonalFeature {
    pub vertices: [Point<Real>; 2],
    pub vids: [PackedFeatureId; 2],
    pub fid: PackedFeatureId,
    pub num_vertices: usize,
}

A polygonal feature representing the local polygonal approximation of a vertex, or face, of a convex shape.

Fields

vertices: [Point<Real>; 2]

Up to two vertices forming this polygonal feature.

vids: [PackedFeatureId; 2]

The feature IDs of this polygon’s vertices.

fid: PackedFeatureId

The feature ID of this polygonal feature.

num_vertices: usize

The number of vertices on this polygon (must be <= 4).

Implementations

impl PolygonalFeature

pub fn transform_by(&mut self, pos: &Isometry<Real>)

Transforms the vertices of self by the given position pos.

pub fn contacts<ManifoldData, ContactData: Default + Copy>( pos12: &Isometry<Real>, pos21: &Isometry<Real>, sep_axis1: &Vector<Real>, sep_axis2: &Vector<Real>, feature1: &Self, feature2: &Self, manifold: &mut ContactManifold<ManifoldData, ContactData>, flipped: bool )

Computes the contacts between two polygonal features.

pub fn face_vertex_contacts<ManifoldData, ContactData: Default + Copy>( pos12: &Isometry<Real>, face1: &Self, sep_axis1: &Vector<Real>, vertex2: &Self, manifold: &mut ContactManifold<ManifoldData, ContactData>, flipped: bool )

Compute contacts points between a face and a vertex.

This method assume we already know that at least one contact exists.

pub fn face_face_contacts<ManifoldData, ContactData: Default + Copy>( pos12: &Isometry<Real>, face1: &Self, normal1: &Vector<Real>, face2: &Self, manifold: &mut ContactManifold<ManifoldData, ContactData>, flipped: bool )

Computes the contacts between two polygonal faces.
