Rotation finding shortest way

[Devostated]

Hello, I wanted to have an axis gizmo to represent the camera angle, but I'm having huge problems, cause the rotation values don't use shortest way. Any idea how this could be fixed ?

    pushMatrix();
    translate(width/2, 50);
    scale(3);
    rotateX((cam.getRotations()[0])*-1);
    rotateY((cam.getRotations()[1])*-1);
    rotateZ((cam.getRotations()[2])*-1);
    shape(axis);
    popMatrix();
