This is from my 3D space screensaver “Planet Quest”, which has been
doing well on download.com recently. Please download from here:
The main features of this screensaver are that the visuals (textures and
geometry) are 100% created procedurally on-the-fly in a worker thread.
Therefore there is no repetition, and scene change is basically
instantaneous. Also, no OpenGL extensions are used so it can run on
reasonably low-end hardware. However, it is fillrate-bound and runs at
the native desktop resolution, so doesn’t perform brilliantly on the
Visuals include: planets, clouds, moons, suns, supernovae, stars,
nebulae, galaxies, planetary rings, asteroids, comets, lens flares. All
For version 4.0 I’ve done a lot of refactoring; for one thing, it dawned
on me that in the previous version, memory fragmentation was a problem.
I also do my own error dialog with minidumps on exceptions and advice to
the user (it is a free-trial software).
Naturally I’d love any feedback!

Looks pretty good. I find the lighting a bit strange in the above
screenshot though.. With a star in that position, you’d expect the
planet to be very dark and a shadow on the ring system (unless we’re
dealing with a binary system having the other star in a quite unlikely
position causing uniform lighting).. Also the galaxy is waaaay to big
and bright.. But what the hell? It looks good :D
how do you know if a galaxy cannot be that big and bright or near enough
in the whole universe? :blink:
Yeah good point.. Guess you cant really.. Except you’d probably have
some serious gravity issues having such a large mass so close (assuming
the field-of-view is not extreme). I guess my point was that you wont
see that in the milkyway.
pretty neato, i admit :D
i downloaded this immediately after i saw this :)
keep up the good work!
Thanks for your comments folks. Its my universe and so I can tell you
categorically that it is commonplace here to have several suns near a
planet! But true, the planet and rings should shade eachother. Not done
Honestly, does it really matter that the lighting is not perfect?
At first glance is a fine scene. With a nice use of colors.
And I like the subject too.
Too much realism would ruin the feel, I guess :)
Oh, almost forgot: GREAT SCREENSAVER!
(give it a try people, it’s well worth it)
Ciao ciao :)
Yeah, I agree. Doesnt have to be super realistic to be cool :D

That’s on my dev PC, Windows XP, ATI Radeon 9800 (not the newest
drivers, though :whistle: ). It’s a dual screen setup (two 17” TFT on
dlu - well that is a bit of a mystery. Invalid error code so no clue
there. It should be running on your primary monitor only, unless you
unchecked a particular checkbox.
Maybe a driver update would fix it, or fiddling with your multimon
