API reference#

Signatures are generated from the live package .d.ts - not hand-written.

curveControlPoints#

function

A curve value's NURBS CONTROL POINTS as [x, y, z] triples — the wire shape the kernel writes them in, and what scene's NurbsCurve spells.

curveControlPoints(geometry: unknown): Point$1[]

curveGeometryToNurbs#

function

Curve entity geometry (a PolyCurve) → the NurbsCurve every other kernel curve call reads. Single nurbs/analytic segments keep exact form via wasm; multi-segment chains sample to a polyline NURBS.

curveGeometryToNurbs(geometry: unknown): NurbsCurve

curveJsonToPolyCurve#

function

Bare Curve (line/arc/ellipse/nurbs) → one-segment PolyCurve.

curveJsonToPolyCurve(segment: Curve): PolyCurve

curveNurbsText#

function

The same recovery as a JSON STRING — what every NurbsCurve.* reader takes as its first argument, without the parse/stringify round trip in between.

curveNurbsText(geometry: unknown): string

curvePoints#

function

A curve value's world polyline — NurbsCurve.tessellate unpacked from its flat [x, y, z, ...] run. A degree-1 control polygon comes back exactly: its chords deviate from it by zero, so no tolerance can subdivide them (measured on an open and a closed polyline).

curvePoints(geometry: unknown, tolerance: number): Point$1[]

isNurbsCurve#

function

isNurbsCurve(value: unknown): value is NurbsCurve

nurbsToPolyCurve#

function

Bare NurbsCurve → one-segment PolyCurve (entity geometry).

nurbsToPolyCurve(nurbs: NurbsCurve): PolyCurve

polyCurveFromPoints#

function

Build a PolyCurve chain of line segments through ordered points.

polyCurveFromPoints(points: Point$1[], closed?: boolean): PolyCurve

toCurve#

function

Coerce to a PolyCurve document. Accepts:

• curve entity
• PolyCurve
• bare NurbsCurve (one-segment wrap)
• bare Curve (type-tagged)
• Point[]

toCurve(value: unknown, options?: { closed?: boolean; }): PolyCurve

toNurbsCurve#

function

Coerce to NurbsCurve (consumers that need control points).

toNurbsCurve(value: unknown): NurbsCurve
