Methods
Name | Description | |
---|---|---|
constructor(blockSize: number, polygon: Float64Array): Bezier1dNd | ||
clonePolygon(result?: Float64Array): Float64Array | Return a clone of the data array. | |
evaluate(s: number, buffer?: Float64Array): Float64Array | Return the curve value at bezier fraction s . |
|
evaluateDerivative(s: number, buffer?: Float64Array): Float64Array | Return the curve derivative value at bezier fraction s . |
|
fractionToParentFraction(fraction: number): number | map a fraction to the parent space. | |
getPolygonPoint(i: number, buffer?: Float64Array): undefined | Float64Array | Return a point of the polygon as a simple array. | |
interpolatePoleInPlace(poleIndexA: number, fraction: number, poleIndexB: number): void | interpolate at fraction between poleA and poleB. |
|
isAlmostEqual(other: any): boolean | equality test with usual metric tolerances | |
loadSpanPoles(data: Float64Array, spanIndex: number): void | Load order * dimension doubles from data[dimension * spanIndex] as poles | |
loadSpanPolesWithWeight(data: Float64Array, dataDimension: number, spanIndex: number, weight: number): void | Load order * (dataDimension + 1) doubles from data[dataDimension * spanIndex] as poles with weight inserted | |
reverseInPlace(): void | block-by-block reversal | |
saturateInPlace(knots: KnotVector, spanIndex: number): boolean | Compute new control points to "clamp" bspline unsaturated support to saturated form. | |
setInterval(a: number, b: number): void | create or update the mapping to parent curve. | |
setPolygonPoint(i: number, buffer: Float64Array): void | set a single point of the polygon as a simple array. | |
subdivideInPlaceKeepLeft(fraction: number): boolean | Apply deCasteljau interpolations to isolate a smaller bezier polygon, representing interval 0..fraction of the original | |
subdivideInPlaceKeepRight(fraction: number): boolean | Apply deCasteljau interpolations to isolate a smaller bezier polygon, representing interval fraction..1 of the original | |
subdivideToIntervalInPlace(fraction0: number, fraction1: number): boolean | Saturate a univariate bspline coefficient array in place | |
unpackToJsonArrays(): any[] | return a json array of arrays with each control point as a lower level array of numbers | |
create(data: Point3d[] | Point4d[] | Point2d[]): undefined | Bezier1dNd Static | Create a Bezier1dNd, using the structure of data[0] to determine the bezier order. |
|
saturate1dInPlace(coffs: Float64Array, knots: KnotVector, spanIndex: number): boolean Static | Saturate a univariate bspline coefficient array in place |
