QParams3d Class

Parameters used for 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.

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: numberQuantization.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: numberQuantization.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: numberQuantization.rangeScale16): QParams3d Static Creates parameters to support quantization of values within the specified range.  
fromZeroToOne(rangeScale: numberQuantization.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.
