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 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: number[] | Point3d[] | Float64Array, weights: number[] | Float64Array, result?: Float64Array): undefined | Float64Array Static | pack each point and its corresponding weight into a buffer of xyzw xyzw ... | |
| packToFloat64Array(data: Point4d[], result?: Float64Array): Float64Array Static | pack x,y,z,w in Float64Array. | |
| unpackFloat64ArrayToPointsAndWeights(data: Float64Array, points: Point3d[], weights: number[], pointFormatter: (x: number, y: number, z: number) => any = Point3d.create): void Static | unpack from xyzw xyzw... | |
| unpackToPoint4dArray(data: Float64Array): Point4d[] Static | unpack from ... |
