API Reference > imodeljs-common > Geometry > QPoint3d QPoint3d Class Represents a Point3d compressed such that each component x, y, and z is quantized to the 16-bit integer range [0, 0xffff]. These are primarily used to reduce the space required for coordinates used by RenderGraphics. see QParams3d to define quantization parameters for a range of points. see QPoint3dList for a list of points all quantized to the same range. Methods Name Description constructor(): QPoint3d Construct with all components initialized to zero. clone(out?: QPoint3d): QPoint3d Create a copy of this point. compare(rhs: QPoint3d): number Perform ordinal comparison to another point. copyFrom(src: QPoint3d): void Set this points components from src. equals(other: QPoint3d): boolean Return true if this point's components are identical to the other point's components. init(pos: Point3d, params: QParams3d): void Initialize this point by quantizing the supplied Point3d using the specified params setFromScalars(x: number, y: number, z: number): void Sets the x, y, and z components directly. unquantize(params: QParams3d, out?: Point3d): Point3d Returns a Point3d unquantized according to the supplied params. create(pos: Point3d, params: QParams3d): QPoint3d Static Creates a quantized point from the supplied Point3d using the specified params fromScalars(x: number, y: number, z: number, out?: QPoint3d): QPoint3d Static Creates a QPoint3d directly from x, y, and z components. Properties Name Type Description x Accessor number The quantized x component. y Accessor number The quantized y component. z Accessor number The quantized z component.
