Comment 42 for bug 1411958

I hope that there is a math description somewhere. It's too complex for me to understand the meaning "getHeliocentricEclipticModelViewTransform" and it's role for coordinates transformation.

Just dumped eyePos before and after the following transformation:
 StelApp::getInstance().getCore()->getHeliocentricEclipticModelViewTransform()->forward(eyePos);

what is the physical meaning of such a vector like
3.81742e-34 5.35747e-17 1.45342e-17
?????

One can see a very strange behavior. Very smooth value changes "before" vs greatly jittered values "after". 3 x zeroes, of course correspond to flick.

Any comment will be greatly appreciated.
