Fields

Lines

Three directed edges. The index is aligned to the begin point: lines[0] = {P0=ps[0], P1=ps[1]}, lines[1] = {P0=ps[1], P1=ps[2]}, lines[2] = {P0=ps[2], P1=ps[0]}.

public readonly TopoLine3Hfr[] Lines

Field Value

TopoLine3Hfr[]

Ps

Three apex points. ps[i] == lines[i].P0.

public readonly TopoPoint3Hfr[] Ps

Field Value

TopoPoint3Hfr[]

Properties

CachedCross

Gets or sets the cached cross product. Setting this is useful when the cross is computed externally (e.g. during construction).

public Vec3Hfr? CachedCross { get; set; }

Property Value

Vec3Hfr?

Methods

ApexAtc(int)

Gets the apex at the specified index.

public Vec3Hfr ApexAtc(int index)

Parameters

index int

Returns

Vec3Hfr

ClearCache()

Clears all cached values.

public void ClearCache()

GetCross()

Gets the cross product vector from line edges: lines[2].arrow x lines[0].arrow. Cached after first computation. Corresponds to C++ get_cross.

public Vec3Hfr GetCross()

Returns

Vec3Hfr

GetCrossByTls(TopoLine3Hfr, TopoLine3Hfr)

Computes cross from line arrows: lines[2].arrow x lines[0].arrow.

public static Vec3Hfr GetCrossByTls(TopoLine3Hfr tl0, TopoLine3Hfr tl2)

Parameters

tl0 TopoLine3Hfr

tl2 TopoLine3Hfr

Returns

Vec3Hfr

GetIntegerNormal()

Gets the integer normal vector (cross scaled to integer-like fraction). Corresponds to C++ get_integer_normal.

public Vec3Hfr GetIntegerNormal()

Returns

Vec3Hfr

GetNormal()

Gets the normalized (unit length) normal vector in double precision. Cached after first computation. Corresponds to C++ get_normal.

public Vec3d GetNormal()

Returns

Vec3d

ResetCross()

Recomputes the cached cross product.

public void ResetCross()

ResetIntegerNormal()

Recomputes the cached integer normal. Also recomputes the cross.

public void ResetIntegerNormal()

ResetNormal()

Recomputes the cached normal. Also recomputes the integer normal and cross.

public void ResetNormal()

ToString()

Returns a string that represents the current object.

public override string ToString()

Returns

string

A string that represents the current object.

ToTri3d()

Converts to a Tri3d (double precision).

public Tri3d ToTri3d()

Returns

Tri3d
