Obtain the rotational value in 3D CSS using JavaScript by extracting it from the matrix3d()

My element has been 3D transformed in the following way:

.foo {
  transform: rotateX(-30deg) rotateY(35deg);
}

Now, I am looking to retrieve these values using JavaScript. Extracting the 3D matrix is simple:

var matrix = $('.foo').css('transform');
// returns:
// matrix3d(0.819152, -0.286788, -0.496732, 0, 0, 0.866025, -0.5, 0, 0.573576, 0.409576, 0.709406, 0, 0, 0, 0, 1)

The challenge lies in calculating CSS values like -30 and 35 from that matrix. While methods exist for 2D transforms, a solution for 3D rotation remains elusive.

Answer №1

Sure, understood!

const _fetchTransform = function($element) {

    let matrix = $element.css('transform'),
        rotateX = 0,
        rotateY = 0,
        rotateZ = 0;

    if (matrix !== 'none') {

        // perform some calculations
        let values = matrix.split('(')[1].split(')')[0].split(','),
            pi = Math.PI,
            sinB = parseFloat(values[8]),
            b = Math.round(Math.asin(sinB) * 180 / pi),
            cosB = Math.cos(b * pi / 180),
            matrixVal10 = parseFloat(values[9]),
            a = Math.round(Math.asin(-matrixVal10 / cosB) * 180 / pi),
            matrixVal1 = parseFloat(values[0]),
            c = Math.round(Math.acos(matrixVal1 / cosB) * 180 / pi);

        rotateX = a;
        rotateY = b;
        rotateZ = c;

    }

    return {
        rotateX: rotateX,
        rotateY: rotateY,
        rotateZ: rotateZ
    };

}
