I can feel it. My mind is going. Wes, stop.

Oooo...colors. Thanks for sharing, Wes. :)

It's also cool when one zooms out of sphere, and then slowly zooms in 

again. When the camera is very close to the sphere, interesting 

artifacts start to emerge on ints surface.

When I put it on full screen on my G5 with 2x2.5 Ghz it kind of stutters! How much processing does it want?

Lower the poly count to make it run faster. It's drawing alot of

vertices. You can also enable displaylists in the gridshape which

vertices.  You can also enable displaylists in the gridshape which
will really give it a speed boost.

It would be nice to be able to navigate through it. It would not turn always in the same direction and maybe one could go inside a bit....

Can you make that interactive Wes?


Part of the fun is learning how to do it yourself :) I'll leave the

navigation to you or someone else. If you get something interesting

share the love and post a modded patch.

yes, I just thought about it. It kind of asks for zoom in and out.

Holy Crap! Wow, on some settings that gives me a full 200% boost. Nice 

Right now I can do 14400 spheres @ dim 6 6, @smooth_shading 1 @fsaa 1 at 

~30 fps - even while I am manipulating both position, color and scale 

and rotation via individual matrices - VERY good - and looks stunning! 

Hehe, also, 40.000 (sic) spinning planes was fun, too!

Thank you for providing probably the most hackable piece of code on here :-D

Just add a toggle to the rotate message and then move about the object 

cluster with your mouse, via the jit.gl.handle object. You can really

seek out cool images that way.

just tryed to find a way to apply zooming. Jitter does not seem to provide 'glPixelZoom'. Inside openGl programming guide 1.4 page328, there is a code example: image.c for zooming.

Did I overlook something in our Jitter box handling zooming?

Does someone know how to put the code into an external?

When I put it on full screen my card a ATI Radeon 9600XT starts sweating. Do you know which card can handle that on full screen?

have you tried the help file for jit.gl.handle ? alt-dragging with the 

mouse zooms in or out - or am I missing what you are trying to acheive?

Hans,

Thanks, yes it does zoom, but it is not very good. Kind of very rough.

Then check the help-file ;-) It will show you which messages 

jit.gl.handle uses to move around - in this case it's [position f f f] -

The problem is my graphics card. It does not zoom smoothly because it is trying already to hard. Which graphics card are you using?

GeForce 8800 GTS (640 MB) - runs like a freakin' dream.

this is really cool . but i dont know why its stop working when im change the dimentions number !

Just substitute the "#1" inside the dim and rotate messages to "$1".

its motion , starts with these changing but its still become black when i change the dim number (the default is 25 that is not working . but when its 0 and not start from beginning and toggle the metro its work .

i find it had some problems . for example in floating and full screen not working with #1 . so i change it to $1 . so it start to work. but its not still working when i change the dim to $1
