Fields
A
#Vertex indices into DelaunayVoronoiResult.Vertices. The tetrahedron (A,B,C,D) is positively oriented in the sense of Shewchuk's orient3d (D lies below the plane of A,B,C, with A,B,C counterclockwise seen from above). Note this is the OPPOSITE sign of the conventional scalar triple product: (B-A).((C-A)x(D-A)) is NEGATIVE for these tets; use |det|/6 for volumes.
B
#Vertex indices into DelaunayVoronoiResult.Vertices. The tetrahedron (A,B,C,D) is positively oriented in the sense of Shewchuk's orient3d (D lies below the plane of A,B,C, with A,B,C counterclockwise seen from above). Note this is the OPPOSITE sign of the conventional scalar triple product: (B-A).((C-A)x(D-A)) is NEGATIVE for these tets; use |det|/6 for volumes.
C
#Vertex indices into DelaunayVoronoiResult.Vertices. The tetrahedron (A,B,C,D) is positively oriented in the sense of Shewchuk's orient3d (D lies below the plane of A,B,C, with A,B,C counterclockwise seen from above). Note this is the OPPOSITE sign of the conventional scalar triple product: (B-A).((C-A)x(D-A)) is NEGATIVE for these tets; use |det|/6 for volumes.
D
#Vertex indices into DelaunayVoronoiResult.Vertices. The tetrahedron (A,B,C,D) is positively oriented in the sense of Shewchuk's orient3d (D lies below the plane of A,B,C, with A,B,C counterclockwise seen from above).

N0
#Indices of the neighbouring tetrahedra opposite A, B, C, D respectively, or -1 where the face is on the convex hull.
N1
#Indices of the neighbouring tetrahedra opposite A, B, C, D respectively, or -1 where the face is on the convex hull.
N2
#Indices of the neighbouring tetrahedra opposite A, B, C, D respectively, or -1 where the face is on the convex hull.
