QPoint2d Class
Represents a Point2d compressed such that each component x
and y
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 - QParams2d to define quantization parameters for a range of points.
- QPoint2dList for a list of points all quantized to the same range.
Methods
Name | Description | |
---|---|---|
constructor(): QPoint2d | Construct with x and y initialized to zero. |
|
clone(out?: QPoint2d): QPoint2d | Create a copy of this point. | |
copyFrom(src: QPoint2d): void | Initialize x and y from src . |
|
init(pos: Readonly<WritableXAndY>, params: QParams2d): void | Initialize this point by quantizing the supplied { x, y } using the specified params | |
setFromScalars(x: number, y: number): void | Set the x and y components directly. | |
unquantize(params: QParams2d, out?: Point2d): Point2d | Return a Point2d unquantized according to the supplied params . |
|
create(pos: Point2d, params: QParams2d): QPoint2d Static | Create a quantized point from the supplied Point2d using the specified params | |
fromScalars(x: number, y: number): QPoint2d Static | Create a QPoint2d directly from x and y components. |
Properties
