DOMMatrixReadOnly: rotateAxisAngle() 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.

Note: This feature is available in Web Workers.

The rotateAxisAngle() method of the DOMMatrixReadOnly interface returns a new DOMMatrix created by rotating the source matrix by the given vector and angle. The original matrix is not altered.

To mutate the matrix as you rotate it, see DOMMatrix.rotateAxisAngleSelf().

Syntax

js
rotateAxisAngle()
rotateAxisAngle(rotX)
rotateAxisAngle(rotX, rotY)
rotateAxisAngle(rotX, rotY, rotZ)
rotateAxisAngle(rotX, rotY, rotZ, angle)

Parameters

rotX

A number; the x-coordinate of the vector denoting the axis of rotation. If non-zero, is2D is false.

rotY Optional

A number; the y-coordinate of the vector denoting the axis of rotation. If undefined, the rotX value is used. If non-zero, is2D is false.

rotZ Optional

A number; the z-coordinate of the vector denoting the axis of rotation. If undefined, the rotX value is used.

angle Optional

A number; the angle of the rotation around the axis vector, in degrees.

Return value

A DOMMatrix.

Examples

js
const matrix = new DOMMatrix(); // create a matrix
console.log(matrix.rotateAxisAngle().toString()); // matrix(1, 0, 0, 1, 0, 0)
console.log(matrix.rotateAxisAngle(10, 20, 30).toString()); // matrix(1, 0, 0, 1, 0, 0)
console.log(matrix.rotateAxisAngle(10, 20, 30, 45).toString());
/* matrix3d(
    0.728, 0.609, -0.315, 0, 
    -0.525, 0.791, 0.315, 0, 
    0.441, -0.063, 0.895, 
    0, 0, 0, 0, 1) */
console.log(matrix.rotateAxisAngle(5, 5, 5, -45).toString());
/* matrix3d(
    0.805, -0.311, 0.506, 0, 
    0.506, 0.805, -0.311, 0, 
    -0.311, 0.506, 0.805, 0, 
    0, 0, 0, 1) */
console.log(matrix.toString()); // output: "matrix(1, 0, 0, 1, 0, 0)" (unchanged)
