I want to know how to get the rotateX and rotateY values of a matrix3d such as this:
matrix3d(0.9999999970415847, 0, 0.00007692093651178932, 0, 0, 1, 0, 0, -0.00007692093651178932, 0, 0.9999999970415847, 0, 0, 0, 300, 1)
does anybody know how to this ? I would really appreciate the help especially since I am not really the math type of person. thnx!
I'm not good at math either, so this needs some checking by someone with more knowledge than me:
var matrix = new WebKitCSSMatrix(el.style.webkitTransform); var rotationX = Math.acos(matrix.a) * (180/pi); var rotationY = Math.asin(matrix.b) * (180/pi);
