Methods

len(line::AbstractLine)

Length of line

len(t::AbstractTriangle)

Circumference of the triangle

area(c::AbstractCube2D)

Signed area of 2D cube

area(t::AbstractTriangle2D)
area(t::AbstractTriangle3D)

Unsigned area of triangle

volume(c::AbstractCube3D)

Signed volume of 3D cube

volume(t::AbstractTetrahedron)

Unsigned volume of tetrahedron

center(line::AbstractLine) = centroid(line)

Average position of line vertices.

centroid(line::AbstractLine)

Average position of line vertices.

centroid(t::AbstractTriangle)

Averaged position center of triangle

centroid(t::AbstractTetrahedron)

Averaged position center of the tetrahedron

midpoint(line::AbstractLine) = centroid(line)

Average position of line vertices.

function orient(a::AbstractPoint2D, b::AbstractPoint2D, c::AbstractPoint2D)

Computes the orient.
The result is also a rough approximation of twice the signed area.

function orient(a::AbstractPoint3D, b::AbstractPoint3D, c::AbstractPoint3D)

Computes the orient.
The result is also a rough approximation of twice the signed area.

function orient(a::AbstractPoint3D, b::AbstractPoint3D, c::AbstractPoint3D, d::AbstractPoint3D)

Computes the orient.
The result is also a rough approximation of six times the signed volume.

orient(t::AbstractTriangle)

Orientation vector of triangle (return a PVector). See also orientation

orient(t::AbstractTetrahedron)

Return a positive number if positively oriented. Return a negative number if negatively oriented. Return zero if not oriented (indicating the tetrahedron has zero volume)

orientation(t::AbstractTriangle2D)

Orientation of triangle. Return a trait (NegativelyOriented, PositivelyOriented, or UnOriented)

orientation(t::AbstractTetrahedron)

Orientation of tetrahedron. Return a trait (NegativelyOriented, PositivelyOriented, or UnOriented)

circumcenter(t::AbstractTriangle)

Return the circumcenter of triangle (as a PVector or PVector2D)

circumcenter(t::AbstractTetrahedron)

Return the circumsphere center of tetrahedron

incircle(t::AbstractTriangle2D, p::AbstractPoint2D)

Test whether a point locates inside the circumcircle of triangle. Return a trait (Interior, Exterior, or OnEdge)

insphere(t::AbstractTetrahedron, p::AbstractPoint3D)

Test whether a point locates inside the circumsphere center of tetrahedron. Return a trait (Interior, Exterior, or OnEdge)
