Enum ncollide3d::shape::TetrahedronPointLocation

pub enum TetrahedronPointLocation<N: RealField> {
    OnVertex(usize),
    OnEdge(usize, [N; 2]),
    OnFace(usize, [N; 3]),
    OnSolid,
}

Logical description of the location of a point on a triangle.

Variants

OnVertex(usize)

The point lies on a vertex.

OnEdge(usize, [N; 2])

The point lies on an edge.

The 0-st edge is the segment AB. The 1-st edge is the segment AC. The 2-nd edge is the segment AD. The 3-rd edge is the segment BC. The 4-th edge is the segment BD. The 5-th edge is the segment CD.

OnFace(usize, [N; 3])

The point lies on a triangular face interior.

The first face is the triangle ABC. The second face is the triangle ABD. The third face is the triangle ACD. The fourth face is the triangle BDC.

OnSolid

The point lies inside of the tetrahedron.

Implementations

impl<N: RealField> TetrahedronPointLocation<N>

pub fn barycentric_coordinates(&self) -> Option<[N; 4]>

The barycentric coordinates corresponding to this point location.

Returns None if the location is TetrahedronPointLocation::OnSolid.

pub fn same_feature_as(&self, other: &TetrahedronPointLocation<N>) -> bool

Returns true if both self and other correspond to points on the same feature of a tetrahedron.
