Get current rotation

[GoogleCodeExporter]

How to get current rotation (x,y,z). I want this to set InitRotation of next 
model (InitRotationX,InitRotationY,InitRotationZ) ?

The function is here. You can add it into jsc3d.js:

/**
 * Get current rotation angles around X, Y and Z axis.
 */
JSC3D.Viewer.prototype.getRotationAngles = function() {
    var angles = [
        Math.atan2(this.rotMatrix.m21, this.rotMatrix.m22) * 180 / Math.PI, // rotX
        Math.asin(-this.rotMatrix.m20) * 180 / Math.PI,                     // rotY
        Math.atan2(this.rotMatrix.m10, this.rotMatrix.m00) * 180 / Math.PI  // rotZ
    ];

    if(angles[0] < 0)
      angles[0] += 360;
    if(angles[1] < 0)
      angles[1] += 360;
    if(angles[2] < 0)
      angles[2] += 360;

    return angles;
};

whose return value is a triple containing current rotation angles around X, Y 
and Z axis.  This was implemented in an experimental branched edition but not 
merged to the main edition.
