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: Readonly<WritableXYAndZ>, params: QParams3d): void | Initialize this point by quantizing the supplied { x, y, z } 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. |
