DOMMatrix: rotateAxisAngleSelf() method

{{APIRef("Geometry Interfaces")}}{{AvailableInWorkers}}

The rotateAxisAngleSelf() method of the {{domxref("DOMMatrix")}} interface is a transformation method that rotates the source matrix by the given vector and angle, returning the altered matrix.

To rotate a matrix without mutating it, see {{domxref("DOMMatrixReadOnly.rotateAxisAngle()")}}, which creates a new rotated matrix while leaving the original unchanged.

Syntax

rotateAxisAngleSelf()
rotateAxisAngleSelf(rotX)
rotateAxisAngleSelf(rotX, rotY)
rotateAxisAngleSelf(rotX, rotY, rotZ)
rotateAxisAngleSelf(rotX, rotY, rotZ, angle)

Parameters

• rotX
  • : A number; the x-coordinate of the vector denoting the axis of rotation. If non-zero, {{domxref("DOMMatrixReadOnly.is2D", "is2D")}} is false.
• rotY {{optional_inline}}
  • : A number; the y-coordinate of the vector denoting the axis of rotation. If undefined, the rotX value is used. If non-zero, {{domxref("DOMMatrixReadOnly.is2D", "is2D")}} is false.
• rotZ {{optional_inline}}
  • : A number; the z-coordinate of the vector denoting the axis of rotation. If undefined, the rotX value is used.
• angle {{optional_inline}}
  • : A number; the angle of the rotation around the axis vector, in degrees.

If rotY and rotZ are both missing, rotZ is set to the value of rotX, and both rotX and rotY are 0.

Return value

A DOMMatrix.

Examples

const matrix = new DOMMatrix(); // create a matrix
console.log(matrix.rotateAxisAngleSelf(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.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)" */
