SpaceTime Screen Saver for Mac OS X is an emmersive, fully 3D screen saver featuring:

• animated Warp Field effect viewable in all three dimensions with blended lighting for additional visual impact.
• customizable settings for warp speed, star density, enabling effects, selecting 3DS meshes, etc.
  

Utilizes my Mesh3DS Framework to enable loading basic 3D Studio MAX (.3ds) meshes easily.

Free as in beer, free as in speech, complete Cocoa source code and Project Builder v2.1 files are provided for SpaceTime Screen Saver, Mesh3DS Framework and a sample program called Display3DS.

No warrantees or restrictions apply to this code; use it as you like in your own projects or to learn Cocoa and/or OpenGL programming on OS X.

SpaceTime is currently untested on Panther; so I'd be grateful if someone would compile SpaceTime with Xcode and contact me with the results at: pinter@p-squared.com (I donated my sunflower imac to my daughter, a senior in college, as she needs the mac way more than I do).

If you find this code useful or instructive, a PayPal donation of a dollar or two would help me replace the mac next year.

Otherwise, if any of this code helps you with Cocoa and/or OpenGL programming on OS X, it has served its purpose.

Cheers,

Hey, this is great! Huge thanks for your generousity!

The build in the .dmg crashes Panther's screen saver control panel:

I expect both the SpaceTime Screen Saver and the Mesh3DS.Framework simply need to be recompiled with Xcode under Panther.

Again, as I no longer have a mac, I'd be grateful if someone would compile and test this kit under Panther and post the results here or e-mail me.

Cheers,
/p2

Anyone? Anyone at all?

Maybe you arent getting enough resposes because the file is 16 megs and times-out (at least with my crappy 56k modem) so I can never d/l the whole thing easily. I cant imagine why the code example is so large (huge models maybe? textures? audio?). Howbout a version with just bare-bones media as an example?

sorry I couldnt be more helpful,

That is the reason I haven't download it yet... started, got 3/4 of the way in and it timed out.

Try using something that allows resumes, such as curl
[code]curl -C - --remote-name http://www.myurl.com/[code]
or something like that...

compiling it in xcode in panther didn't fix the problem

Okay, thanks SkyHawk and thanks to all who tried.

Unless anyone has time to fix the Panther specific problem, I won't be able to fix the problem till I replace my Mac next year (those new 20" imacs look especially attractive).

Cheers,

Okay, I've spent about 10 minutes on this thing trying to fix it up it and seems this line in Mesh3ds.m (in the framework) is the cuprite:

-(void)Display {glCallList (DisplayListNumber);}

if I comment the display list call out the screen saver so now of course the screensaver runs without crashing but without drawing any of the models on screen either.

If you have any thoughts why the display list would crash let me know....

Otherwise I can build the changes for both and you can upload them to your website for the world.

Hope I could help,
Derek

Panther has issues with display lists which embed vertex array calls. They crash.

stauffer@apple.com said on Nov 8 2003 that they found and fixed the problem, so this might work in 10.3.2? If not, the only workaround is to use immediate mode.
