nodeMethods/toCurve#

curveControlPoints()#

curveControlPoints(geometry): Point[]

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.

Parameters#

geometry#

unknown

Returns#

Point[]

curveGeometryToNurbs()#

curveGeometryToNurbs(geometry): NurbsCurve

Curve document 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.

Parameters#

geometry#

unknown

Returns#

NurbsCurve

curveJsonToPolyCurve()#

curveJsonToPolyCurve(segment): PolyCurve

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

Parameters#

segment#

Segment

Returns#

PolyCurve

curveNurbsText()#

curveNurbsText(geometry): string

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

Parameters#

geometry#

unknown

Returns#

string

curvePoints()#

curvePoints(geometry, tolerance): Point[]

A curve value's world polyline — PolyCurve.tessellate unpacked from its flat [x, y, z, ...] run. Line segments emit their endpoints exactly; curved segments subdivide to the CALLER's chord tolerance. The old route through curveNurbsText capped that tolerance at the door's own chain sample (CHAIN_SAMPLE_TOLERANCE = 0.5, crates/geometry/src/curve/to_curve.rs), so a caller asking for 0.01 got 0.5 and never heard about it.

Parameters#

geometry#

unknown

tolerance#

number

Returns#

Point[]

isNurbsCurve()#

isNurbsCurve(value): value is NurbsCurve

Parameters#

value#

unknown

Returns#

value is NurbsCurve

nurbsToPolyCurve()#

nurbsToPolyCurve(nurbs): PolyCurve

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

Parameters#

nurbs#

NurbsCurve

Returns#

PolyCurve

parsePolyCurve()#

parsePolyCurve(value): PolyCurve

Parse / assert a PolyCurve document.

Parameters#

value#

unknown

Returns#

PolyCurve

polyCurveFromPoints()#

polyCurveFromPoints(points, closed?): PolyCurve

Build a PolyCurve chain of line segments through ordered points.

Parameters#

points#

Point[]

closed?#

boolean = false

Returns#

PolyCurve

polyCurveText()#

polyCurveText(geometry): string

A curve value as the PolyCurve JSON STRING every PolyCurve.* reader takes — the chain's OWN text, with no NURBS recovery in between. This is the door for the whole poly_curve_* roster: each kind is measured natively (a line by distance, an arc by radius x |sweep|), so nothing is chorded before it is asked a question.

Parameters#

geometry#

unknown

Returns#

string

toCurve()#

toCurve(value, options?): PolyCurve

Coerce to a PolyCurve document. Accepts:

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

Parameters#

value#

unknown

options?#

closed?#

boolean

Returns#

PolyCurve

toNurbsCurve()#

toNurbsCurve(value): NurbsCurve

Coerce to NurbsCurve (consumers that need control points).

Parameters#

value#

unknown

Returns#

NurbsCurve

unflattenPoints()#

unflattenPoints(samples): Point[]

Flat [x, y, z, ...] kernel run -> [x, y, z] triples.

Parameters#

samples#

ArrayLike<number>

Returns#

Point[]

isPolyCurve#

Re-exports isPolyCurve
