Rotate camera function

Question

Hello,
I'm starting to write a code for Acrobat and 3d Objects.
What I need is a function that rotates an object given a yaw and a pitch (i.e. rotateObjectYaw(45) to rotate the object 45 degrees around, rotating the camera, not the object itself).
I started modifying the CameraRotate.js and I already made it work eliminating the friction effect and performing the full delta change in one iteration.
Yaw works perfectly, but the problem is the pitch. If I rotate the Yaw first, the pitch does not rotate around the changed axis but on the original pitch axis. I guess the problem lies somewhere around:
        // Update camera direction
        var x = Math.sin( yaw   ) * Math.cos( pitch );
        var y = Math.cos( yaw   ) * Math.cos( pitch );
        var z = Math.sin( pitch );
        cameraDirection.set( x, y, z );
        // Update camera position
        trueCameraPos.set(targetPosition);
        trueCameraPos.addScaledInPlace(cameraDirection, cameraDistance * GlobalZoomScale);
        camera.up.set(targetPosition.x, targetPosition.y, targetPosition.z + cameraDistance);
        camera.position.set(trueCameraPos);
        camera.targetPosition.set(targetPosition);
But I'm not sure, and I have no idea about vector space calculations and so. Can somebody help me out?

Mike,
Can you put this in the Rich Media & 3D forum: http://forums.adobe.com/community/acrobat/acrobat_3d_features
