TriangulateSurface()

Breaks the loop into triangles that each lie within it, each arc cut finely enough that it strays no further than the automatic share of its radius, using the default tolerance.

public GeoTriangle2[] TriangulateSurface()

Returns

GeoTriangle2[]

The triangles covering the flattened loop, counter-clockwise; none when it encloses no area.

TriangulateSurface(Tolerance)

Breaks the loop into triangles that each lie within it, each arc cut finely enough that it strays no further than the automatic share of its radius, within a tolerance.

public GeoTriangle2[] TriangulateSurface(Tolerance tolerance)

Parameters

tolerance Tolerance

The tolerance deciding what counts as no area, and how near two edges may come.

Returns

GeoTriangle2[]

The triangles covering the flattened loop, counter-clockwise; none when it encloses no area.

TriangulateSurface(double)

Breaks the loop into triangles that each lie within it, each arc cut so that it strays no further than a chord tolerance, using the default tolerance.

public GeoTriangle2[] TriangulateSurface(double chordTolerance)

Parameters

chordTolerance double

The largest gap allowed between a piece and the arc it replaces, in drawing units. Zero picks the automatic share of each radius.

Returns

GeoTriangle2[]

The triangles covering the flattened loop, counter-clockwise; none when it encloses no area.

TriangulateSurface(double, Tolerance)

Breaks the loop into triangles that each lie within it, each arc cut so that it strays no further than a chord tolerance, within a tolerance.

public GeoTriangle2[] TriangulateSurface(double chordTolerance, Tolerance tolerance)

Parameters

chordTolerance double

The largest gap allowed between a piece and the arc it replaces, in drawing units. Zero picks the automatic share of each radius.

tolerance Tolerance

The tolerance deciding what counts as no area, and how near two edges may come.

Returns

GeoTriangle2[]

The triangles covering the flattened loop, counter-clockwise; none when it encloses no area.

Remarks

The loop is flattened as Flatten(double) flattens it, and the corners the arcs are cut at lie on the arcs, so a loop bulging outward is covered a little short of its arcs and one bulging inward a little past them, by no more than the chord tolerance.

Exceptions

ArgumentOutOfRangeException

Thrown when the chord tolerance is negative or not a number.
