DOMMatrix: scale3dSelf() method

Baseline Widely available

This feature is well established and works across many devices and browser versions. It’s been available across browsers since January 2020.

See full compatibility

Note: This feature is available in Web Workers.

The scale3dSelf() method of the DOMMatrix interface is a mutable transformation method that modifies a matrix by applying a specified scaling factor to all three axes, centered on the given origin, with a default origin of (0, 0, 0), returning the 3D-scaled matrix.

To 3D-scale a matrix without mutating it, see DOMMatrixReadOnly.scale3d(), which creates a new scaled matrix while leaving the original unchanged.

Syntax

scale3dSelf()
scale3dSelf(scale)
scale3dSelf(scale, originX)
scale3dSelf(scale, originX, originY)
scale3dSelf(scale, originX, originY, originZ)

Parameters

scale: A multiplier; the scale value. If no scale is supplied, this defaults to 1. If scale is not 1, the is2D property of the current matrix is set to false.
originX Optional: An x-coordinate for the origin of the transformation. If no origin is supplied, this defaults to 0.
originY Optional: A y-coordinate for the origin of the transformation. If no origin is supplied, this defaults to 0.
originZ Optional: A z-coordinate for the origin of the transformation. If no origin is supplied, this defaults to 0.

Return value

Returns itself; a DOMMatrix.

Examples

const matrix = new DOMMatrix();
console.log(matrix.scale3dSelf(2).toString());
/* matrix3d(
    2, 0, 0, 0, 
    0, 2, 0, 0, 
    0, 0, 2, 0, 
    0, 0, 0, 1) */
console.log(matrix.scale3dSelf(3.1, 25, 25, 1.25).toString());
/* matrix3d(
    6.2, 0, 0, 0,
    0, 6.2, 0, 0, 
    0, 0, 6.2, 0, 
    -105, -105, -5.25, 1) */
console.log(matrix.toString());
/* matrix3d(
    6.2, 0, 0, 0, 
    0, 6.2, 0, 0, 
    0, 0, 6.2, 0, 
    -105, -105, -5.25, 1) (same as above) */
