curvePointsJson#

const curvePointsJson: (requests_json) => string = wasm.nurbs_curve_points_json

Evaluate many NURBS curves at once. Input is a JSON array of {degree, knots, controlPoints, weights, t} objects; output is a JSON array of [x, y, z] in the same order. Whole-table, so a reader that samples every NURBS row (start / quarter / mid / end) does not call [nurbs_curve_point] inside that loop.

Parameters#

requests_json#

string

Returns#

string

curveSplit#

const curveSplit: (curve_json, t) => string = wasm.nurbs_curve_split

Both halves, as a JSON array of two NurbsCurveJSON.

Parameters#

Parameters#

curve_json#

string
