QParams3d Class
Parameters used for QParams3d.Quantization of 3d points such that the x, y, and z components are each quantized to 16-bit unsigned integers.
see QPoint3d for the quantized representation of a Point3d.
see QPoint3dList for a list of QPoint3ds quantized using a QParams3d.

Methods
| Name | Description | |
|---|---|---|
| clone(out?: QParams3d): QParams3d | Create a copy of these parameters. | |
| computeRange(out?: Range3d): Range3d | Compute the range to which these parameters quantize. | |
| copyFrom(src: QParams3d): void | Set x, y, and z from `src. |
|
| isQuantizable(point: Point3d): boolean | Return true if the point point is quantizable using these parameters. | |
| setFromOriginAndScale(origin: Point3d, scale: Point3d): void | Initialize from origin and scale | |
| setFromRange(range: Range3d, rangeScale: number = Quantization.rangeScale16): void | Initialize these parameters to support quantization of values within the specified range. | |
| unquantize(x: number, y: number, z: number, out?: Point3d): Point3d | Return the unquantized point for the input components. | |
| fromNormalizedRange(rangeScale: number = Quantization.rangeScale16): QParams3d Static | Creates parameters supporting quantization of values within the range [-1.0, 1.0]. | |
| fromOriginAndScale(origin: Point3d, scale: Point3d, out?: QParams3d): QParams3d Static | Creates parameters supporting quantization of values within the range [-1.0, 1.0]. | |
| fromRange(range: Range3d, out?: QParams3d, rangeScale: number = Quantization.rangeScale16): QParams3d Static | Creates parameters to support quantization of values within the specified range. | |
| fromZeroToOne(rangeScale: number = Quantization.rangeScale16): QParams3d Static | Creates parameters supporting quantization of values within the range [0.0, 1.0]. |
Properties
| Name | Type | Description | |
|---|---|---|---|
| origin Readonly | Point3d | The origin of the quantization range. | |
| scale Readonly | Point3d | The scale applied to coordinates to quantize them. |
