Hi there,
I have a patch with two balls moving but the movement isn't smooth.....what can I do to optimize the refreshment of the images and get a smoother movement?
I'm using PD and GEM in an iBook OSX.
Cheers,
Enrique
halo.
i'm not familiar with ibooks opengl performance but have you tried:
- sending a [frame $1[ message to gemwin
- making the balls move in smaller steps
?
if you send your patch we could have a look at it.
smooth. joreg.

well, this depends: first: do you have a fast graphics card ? geforce should be ok. the example patch 07.texture/04.moveImages.pd is a good starting point. if the spheres move smoothly, try optimizing your patch if they don't, you might have no hw-acceleration. if the XServer (i guess osX is Xserver-based...) eats 99% this is surely the problem. try getting a good card with an appropriate driver.
if this patch is ok, you might want to set the refresh-rate of the gemwin with a message like "frame 30" (which gives you 30 fps)
and of course be sure, that you update your movement accordingly: a translation by 1 each second will naturally be more jerky than wee translations of 0.02 each 50ms.

hi enrique, ...kinda hard to figure out what the smooth-lack problem is without seeing a patch...
well, this depends: first: do you have a fast graphics card ? geforce should be ok.
since it's an ibook, that means it has an ATI card, possibly a rage 128 mobility...but I wouldn't imagine this to be the problem...

well, OS X GEM doesn't use XServer, it is setup to use AGL and the 'aqua'-native windowing system...tho it could be possible now to set up a link with the Xserver, because XFree86 is now sporting native opengl acceleration...but I haven't tried it, it's probably buggy, and apple's windowing system works fine...

One can't replace laptop graphics cards, to my knowledge...

hi IOhannes, ...did you ever open an official GEM CVS repository? I've got plenty of changes to file, all OS X-centric, in addition to the projectBuilder project file...Chris Clepper has been helping out a bit, and we're wanting to take GEM into YUV processing completely, instead of RGB (due to decompressor preferences and the new apple GL extension that allows YUV textures...)
whatcha think?

- try sending a [frame 30< message to the gemwin. you can try higher
than 30 as well.
- make sure there are no 'spinning' number boxes (constantly updating)
- are you using a metro and rotate in the patch? rotate will be
jerky unless the metro is set really low like < 10 msec. you will also have to increase the frame amount to see the result.

are you running 10.2? the GL in jaguar is very much improved and has spiffy new features.
i've got a powerbook with the rage chip and nothing that simple in gem really stresses it. now if you have a newer ibook with the radeon, then i'm not sure how quartz extreme plays into the equation. it might be eating all the vram. if you install the dev tools you get a nifty openGL profiling app that will tell you what the vram situation is.

he does have acceleration. in fact you have to try really hard to disable it in OSX.

OSX does not use X11, but you can certainly install it if you wish. pd/GEM use native windowing in OSX.

not an option for his ibook. but in general any radeon/geforce running in 10.2 should be quite nice for GEM.
