Public Member Functions
void	CalculateInnerMatrix (const ea::vector< Vector3 > &vertices)
	Calculate matrix for valid inner tetrahedron.

void	GetTriangleFaceIndices (unsigned faceIndex, unsigned(&indices)[3]) const
	Return indices of specified triangle face of the tetrahedron.

TetrahedralMeshSurfaceTriangle	GetTriangleFace (unsigned faceIndex, unsigned tetIndex, unsigned tetFace) const
	Return triangle face of the tetrahedron. Adjacency information is left uninitialized.

unsigned	GetNeighborFaceIndex (unsigned neighborTetIndex) const
	Return face index corresponding to given neighbor. Return 4 if not found.

bool	HasNeighbor (unsigned neighborTetIndex) const
	Return whether the tetrahedron has given neighbour.

Public Attributes
unsigned	indices_ [4] {}
	Indices of tetrahedron vertices.

unsigned	neighbors_ [4] { M_MAX_UNSIGNED, M_MAX_UNSIGNED, M_MAX_UNSIGNED, M_MAX_UNSIGNED }
	Indices of neighbor tetrahedrons. M_MAX_UNSIGNED if empty.

Matrix3x4	matrix_
	Pre-computed matrix for calculating barycentric coordinates.

Static Public Attributes
static const unsigned	Infinity3 = M_MAX_UNSIGNED
	Special index for infinite vertex of outer tetrahedron, cubic equation.

static const unsigned	Infinity2 = M_MAX_UNSIGNED - 1
	Special index for infinite vertex of outer tetrahedron, square equation.
