Yes, the Fink and GNU/Darwin versions of PyMOL are unaccelerated. As = far as I know, the only way to get access to hardware is to call Apple's = platform-specific OpenGL libraries from within a platform-specific = window. =20 I am still working on the native OSX port, but with competition from all = the other PyMOL priorities: such as new features, bug-fixes, and = support, not to mention my own career and personal life, it is taking = far longer to complete than I anticipated. =20 There was an incomplete test version available with acceleration, but OS = 10.2 has reportedly broken it. If you can put up with software rendering, then X-windows based Fink or = GNU/Darwin versions are fine. But if you want fast PyMOL, then an = x86-based PC with Windows or Linux is the only alternative (we're = talking about a 10-50X performance difference of hardware over software = -- huge!). Plus, PC's can do stereo -- Macs can't. If you need fast 3D graphics on a Mac, I'd encourage you to look around = for other 3D viewers for at least the next couple months. VMD = reportedly has a native version...though I haven't tried it myself. Warren -- mailto:wa...@su... Warren L.

If there > is a > trick here that I am missing please let me know. > I suggest you to use the beta of the native MacOS X version: http://prdownloads.sourceforge.net/pymol/pymol-0_79a.dmg.gz Although it's a beta, it should be blazingly fast on a G4. Attention, it's a pre 0.8 version and the last features are not implemented. Moreover, the menus are not implemented at all. By the way, for some reasons, the prompt in PyMol's window is not accessible when using MacOS X version 10.2. So if you want to keep the beta functional, either don't upgrade or keep MacOS X.1 as a dual boot option. Hopefully, Warren will fix this soon. regards, |
