	One face's term in a vertex's angle-weighted pseudonormal: the face's normal weighted by the angle the face subtends at the vertex.

template<class T >

Vec3T< T > EBGeometry::DCEL::VertexDetail::angleWeightedTerm ( const Vec3T< T > &  a_x0, const Vec3T< T > &  a_x1, const Vec3T< T > &  a_x2, const Vec3T< T > &  a_normal  )

inlineprotectednoexcept

One face's term in a vertex's angle-weighted pseudonormal: the face's normal weighted by the angle the face subtends at the vertex.

The host's reconcile and DCEL::reconcile() both take their terms from here, so that their arithmetic cannot drift apart. The positions must be distinct.

Template Parameters

T	Floating-point precision.

Parameters

[in]	a_x0	The vertex's position.
[in]	a_x1	The position of the vertex before it on the face.
[in]	a_x2	The position of the vertex after it on the face.
[in]	a_normal	The face's normal.

Returns

The angle at a_x0 between the edges to a_x1 and a_x2, times a_normal.
