Sphere orientation

that way of creating a quaternion is probably not very useful unless you are getting the values from some calculation. the easiest is to use:

ofQuaternion(angle, axis);

where axis is an ofVec3f to aplly the angle to. for example to rotate the object 90 degrees in z:

spehere.setOrientation(ofQuaternion(90,ofVec3f(0,0,1));
