Enum oxygengine_physics_2d::prelude::TrianglePointLocation [−][src]
pub enum TrianglePointLocation<N> where
N: RealField + Copy, {
OnVertex(usize),
OnEdge(usize, [N; 2]),
OnFace(usize, [N; 3]),
OnSolid,
}
Expand description
Description of the location of a point on a triangle.
Variants
OnVertex(usize)
Tuple Fields
0: 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
The barycentric coordinates corresponding to this point location.
Returns None
if the location is TrianglePointLocation::OnSolid
.
Returns true
if the point is located on the relative interior of the triangle.
