Enum ncollide3d::shape::TrianglePointLocation

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

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 BC. The 2-nd edge is the segment AC.

OnFace(usize, [N; 3])

The point lies on the triangle interior.

The integer indicates on which side of the face the point is. 0 indicates the point is on the half-space toward the CW normal of the triangle. 1 indicates the point is on the other half-space. This is always set to 0 in 2D.

OnSolid

The point lies on the triangle interior (for “solid” point queries).

Implementations

impl<N: RealField> TrianglePointLocation<N>

pub fn barycentric_coordinates(&self) -> Option<[N; 3]>

The barycentric coordinates corresponding to this point location.

Returns None if the location is TrianglePointLocation::OnSolid.

pub fn is_on_face(&self) -> bool

Returns true if the point is located on the relative interior of the triangle.

Trait Implementations
