Hi !
I am visualising a sun system, and have the following problem, due the
large distances between the planets.
It happens just to pluto (i guess, because its the farest from the sun,
and relatively small).
The sun is in (0,0,0).
When i see pluto and move or turn. then i do not see a smooth movement
of the planet,
but it just appears in some discrete locations.
That does not look very nice.
I would guess this is because the movement/rotation of your viewpoint is
computed from mouse coordinates (i.e. the pixel position of the mouse on
the screen). As your a far from the origin of your coordinate system,
your viewpoint moves/rotates in visible steps, while when you are close
to the origin these steps are so small you notice them as being smooth.
It does not happen to the objects that are closer to the sun (even if
they have similar radius, like our moon)
Size of objects should not matter here, but distance from the origin does ;)
p.s: Far and Near Clipping planes, are already set to needed values, so
changing them is not a good solution.
Any Suggestions ?
You might scale your whole model, so the computation is done with
numbers of a smaller magnitude.
If that's not a option, it's probably possible to do the computations
yourself - maybe someone with knowledge on the
Navigator/SimpleSceneManager stuff can comment on this in detail...
Greetings

Hope it helps,
