Point4dArray Class
The Point4dArray class contains static methods that act on arrays of 4d points.
Methods
| Name | Description | |
|---|---|---|
| constructor(): Point4dArray | ||
| isAlmostEqual(dataA: undefined | Float64Array | Point4d[], dataB: undefined | Float64Array | Point4d[]): boolean Static | Test arrays for near equality of all corresponding numeric values, treated as coordinates. | |
| isCloseToPlane(data: Float64Array | Point4d[], plane: Plane3dByOriginAndUnitNormal, tolerance: number = Geometry.smallMetricDistance): boolean Static | return true iff all xyzw points' altitudes are within tolerance of the plane. | |
| multiplyInPlace(transform: Transform, xyzw: Float64Array): void Static | Multiply (and replace) each block of 4 values as a Point4d. | |
| packPointsAndWeightsToFloat64Array(data: Float64Array | number[] | Point3d[], weights: Float64Array | number[], result?: Float64Array): undefined | Float64Array Static | Copy each weighted point and its corresponding weight into a packed buffer. | |
| packToFloat64Array(data: Point4d[], result?: Float64Array): Float64Array Static | Copy 4d points into a packed buffer. | |
| unpackFloat64ArrayToPointsAndWeights(data: Float64Array, points: Point3d[], weights: number[], pointFormatter: (x: number, y: number, z: number) => any = ...): void Static | Unpack packed 4D data to a Point3d array and an array of weights. | |
| unpackToPoint4dArray(data: Float64Array): Point4d[] Static | unpack from ... |
