hi all! i am making a videoinstallation for a library using quartz
and i've run into two issues which i hope you could help me with :)
1. i've made a patch which is quite similar to the image-queue
example in /Developer/Examples/Quartz/Concepts/, its a quite heavy
patch running in ~30-50fps on my mbook pro (1rev) 2GB ram. earlier
today i tested the patch on my gf:s brand new iMac and i got like
~2fps. although there is a 2.4ghz intel core2duo in her machine (my
mbook has the old intel duo core 2.0ghz).. i guess the on board gfx-
card on my laptop couldnt be that much better than the gfxboard the
new imacs are shipped with.. are there any opengl-driver issues or
similar with the new imacs?
Not that we are aware of. If you find performance problems like this,
please file a bug.
Bear in mind that there are many factors: CPU, RAM, graphics card,
disk speed, etc. You did not mention how much ram the iMac has, is it
comparable to the 2GB in your macbook pro? The queue patch is very
resource intensive, especially if you are doing it full screen since
the iMac will have many more pixels to save.
2. i am using some image-with-string objects with custom fonts in a
patch which i am compiling into a stand-alone app using QCView..
is there any way to bundle the .app with the fonts i am using?
Should work just like loading any other font in a cocoa application. I
haven't done it myself but I believe ATS (apple text system) is the
place to look.
