System 7.5.1 was the first to refer to itself as Mac OS; Mac OS 7.6 was the first to be branded as 'Mac OS' Mac OS 8: 1997 1997 Macintosh computers Mac OS 9: 1999 1999 Mac OS X: Mac OS X Public Beta: September 13, 2000 September 13, 2000 May 14, 2001 Code name Kodiak; Mac OS X 10.0: September 13, 2000 March 24, 2001 Code name Cheetah; Mac OS X 10.1. Maya was developed by Alias and is released for the Microsoft Windows, Linux, IRIX, and Mac OS X operating systems. The latest version of Maya, version 8.0, was released in August 2006. 6.5 was the last version that supported IRIX, due to the platform's declining popularity in recent years.

Thermal Physics

  • Molecules is a two-dimensional molecular dynamics simulation of a collection of structureless, interacting particles (such as noble gas atoms). Uses of this program range from visualizing frictionless motion to quantitative study of phase transformations. The full-featured user interface lets you create up to 1000 particles of two different types, adjust their sizes, masses, and interaction strengths, add a gravitational field, monitor the temperature and pressure, and save configurations for later use. This program is available for several platforms:
    • Mac OS 8-9. Also runs in the Classic environment under OS X. Click here to download (.sit format, 792k).
    • Mac OS X. Also runs under OS 9 with CarbonLib. Note that, due to the double-buffered graphics on OS X, the Classic version (above) gives better performance and smoother animation (though with some flicker). Click here to download (.sit format, 975k).
    • Windows 95 or better. Click here to download (.zip format, 536k).
    • REALbasic project source file. If you have REALbasic, just click here to download the project file (.sit format, 143k).
    • Source code in plain text format (61k; possibly useful if you want to see the algorithms or port the program).
    • This software is issued under the GNU General Public License, which you should read if you intend to modify or distribute the program.
    • There's also a stripped-down Java version of this program: click here to view or download the source code.
  • Ising is a Monte Carlo simulation of the two-dimensional Ising model, demonstrating phase transitions of a magnetic system. You can adjust the temperature, magnetic field, and lattice size (up to 400x400) while the simulation is running. Besides graphical output, the program keeps track of the current value, average, and standard deviation of the energy and magnetization, which you can copy and paste into a spreadsheet for further analysis. The current version of Ising is 1.1, posted 22 September 2002 (see source code for a list of changes since version 1.0). This program is available for several platforms:

The programs described below were developed for the Macintosh computer circa 1985-92. They are small, fast, and easy to use, but lack the color graphics that everyone expects these days. As far as I know, all of them run fine on PowerPC-based Macintosh systems, including OS X systems under the Classic environment. It might be possible to run them on Intel-based Macs using third-party emulation software, but I've never tried this. Except for the EField Appet (see above), I have no versions of these programs for Windows or other operating systems. However, the Spins program has recently been ported to Java by a group at Oregon State University. Click here for more information about this Java version of Spins.

All of the programs described below, except for the Radiation program, were written by Dan Schroeder and Michael Martin. To download an archive of all of these programs, click here (.hqx format, 213k). The Radiation program is in a separate archive (see below).

Electromagnetism

  • E-Field shows the electric field (represented by arrows) of an arbitrary two-dimensional distribution of point charges or of infinite-line charges (running perpendicular to the screen). It has a very easy user interface and is suitable for high school or college introductory courses. (Unless you're on a pre-OSX Mac, use the EField applet instead of this program.)
  • B-Field is similar to E-Field but shows the magnetic field of an arbitrary arrangement of infinite wires running perpendicular to the screen.
  • Radiation draws and animates the electric field lines around an accelerated point charge undergoing various motions, as described here. This program was created by Blas Cabrera, Sha Xin Wei, and Jim Terman; it is now in the public domain. Click here to download this program (.hqx format, 40k).

Fourier Analysis

  • Fourier analyzes a user-drawn wave form (within a finite interval) into its first 15 Fourier components, or synthesizes a wave form from user-specified coefficients.

Quantum Mechanics

  • Q-Wave is similar to Fourier, but can analyze a wavefunction using any of three different sets of basis functions, corresponding to box, harmonic oscillator, and linear potential energy functions.
  • Schrödinger animates the time dependence of a one-dimensional wavefunction built as a linear superposition of the first six basis functions for either the box or harmonic oscillator potential.
  • Quantum1D is a bare-bones animation (with no user interface) of one-dimensional scattering of a wavepacket from a step potential. A few parameters can be specified by the user upon startup.
  • Spins allows the user to link together Stern-Gerlach devices to explore the mysteries of quantum mechanics for a system that is mathematically very simple. This program is described in an article in American Journal of Physics 61, 798-805 (1993). New: a Java version of this program is now available from Oregon State University.

MAIN INDEX of latest speed tests

GeForce 6800 Ultra DDL graphics card
versus others

Special thanks to 'remote mad scientist,' hackintosh,

Lifeblood arena mac os. The NVIDIA GeForce 6800 Ultra DDL is the new top end 8X AGP graphics card for the G5 Power Mac. It's the only card that will drive the new 30' Apple Cinema Display. But you don't have to have that display to take advantage of the card's speed. You can use it with any display. Though our test unit hasn't arrived yet, with the help of a 'remote mad scientist,' we have some performance data for you. This page has results running on a 17' LCD display at 1280x1024. For results at 1920x1200, see our OTHER GeForce 6800 PAGE.

The Unreal Tournament 2004 (UT2004) test was done using SantaDuck LCDBench for at Maximum Settings. We chose the FLYBY posted above because it's one of the best ways to measure the contribution of the GPU over the CPU. In the graph below, we show the BOTMATCH using the same tool and settings. It is a CPU 'bound' test, so it makes little or no difference what card you use.

Halo tends to use a combination of CPU and GPU to do its thing. We either turned on or set 'high' every feature to stress the GPU. Slimefrog mac os. The exceptions were Lens Flare, Sound Quality, and Sound Variety which we set to low since those are CPU functions.

Remnants of the precursors mac os. In consultation with the Halo developers, we came up with these settings to stress the graphics cards:
HW Shaders = ATI Pixel and Vertex Shaders*, FSAA = 4X,
Lens Flare = low, Model Quality = high
VIDEO: Resolution 1280x1024, Refresh = 0, Framerate Throttle = no vsync
Specular = on, Shadows = on, Decals = on,
Particles = high, Texture Quality = high
SOUND: Sound = on, Sound Quality = low, Sound Variety = low

(* At the suggestion of the Halo developers, we made two kinds of runs with the GeForce 6800 -- one using NVIDIA NV and Vertex Shaders and one using ATI Pixel and Vertex Shaders. Note that ATI shaders produced the higher frame rate.)

Quake 3 Arena fans will be happy to know that it ROCKS on the GeForce 6800:

Motion is the newest test of graphic cards. As you can see below, how fast you can render a project for preview depends on your graphics card's speed as much as it does on your cpu speed. A G5/2.5GHz Power Mac with a GeForce 6800 renders the 300 frame 'Fire - Mortise 2' template 38% faster than the same computer with a Radeon 9800 XT and 86% faster than the same computer with the Radeon 9600 XT. That's almost like having a third CPU. Color switcher (eyadthegreat) mac os.

CONCLUSIONS
The NVIDIA GeForce 6800 Ultra DDL is more than a card for driving a 30' display. It's got some real horsepower for running 3D accelerated games. And as we found out, it screams when you render Motion RAM PREVIEWs.

Being a 'madman' for speed, I am definitely lusting over this card. However, be aware of the fact that it 'eats' one of your PCI-X slots. The large heatsink/fan assembly encroaches on the PCI-X slot adjacent to the AGP slot. So if you are depending on having all three PCI-X slots available for use in your G5, this is not the card for you. Ditto for the Radeon 9800 XT. That might be why Apple is offering the Radeon 9800 Pro SE as a kit.

If you are one of those who bought the RocketRAID 8 port SATA PCI-X adapter, you might still be able to route the data cables out through the back of slot 2 with the backplate off.

Is the $599 aftermarket GeForce 6800 kit worth 50% more than the Radeon 9800 Pro Special Edition kit to get up to 115% more 3D game speed. Yeah.

Is the Configure-To-Order (CTO) $450-$500 GeForce 6800 worth 41%-50% more than the CTO Radeon 9800 XT to get up to 102% more 3D game speed. Duh.

It may seem cheaper if you buy the GeForce 6800 as a CTO option on your new G5 -- but remember, that $450-$500 addon price includes the 'credit' for the Radeon 9600 XT or GeForceFX 5200 it replaces. Hmmm. That gives me an idea: Why not sell your old card on eBay to help recover some of the cost of your 'smokin' GeForce 6800?

FLASH: ATI showed off a Radeon X800 graphics card running on a G5 at the Digital Life Expo in New York this week. It only uses one slot and they are confident will match the performance of the GeForce 6800 Ultra. We hope to verify that soon.

CAUTION: I've been informed that a bunch of guys who got their 6800's are reporting that the card causes OS X 10.3.5 or lower to crash if the driver is not installed. This means that the Apple Install DVD is useless with the card in the slot. It also means that you can't reinstall the OS or fix permissions while booting off the DVD. It's probably a good idea to install the driver before you install the card. Then I suggest using Carbon Copy Cloner to make a back up drive that can booted from with the card installed. You may also want to make a bootable Install DVD as suggested on Blargatron.

WHERE TO BUY FAST GRAPHICS CARDS
The Apple Online Store offers the 9600 XT ($50), 9800 XT ($300-$350), and GeForce 6800 ($450-500) as 'configure-to-order' (CTO) options when purchasing a new G5 Power Mac.

If you already own a G5 Power Mac and want to upgrade to the 9600 XT or 9800 XT, you can't. They aren't available as kits from Apple (yet). And they aren't in retail channels (yet). Apple's Online Store does, however, sell aftermarket kits for the Radeon 9800 Pro 'Mac Special Edition' ($399) and the GeForce 6800 Ultra DDL ($599).

There are various resellers carrying the Radeon 9800 Pro Mac Special Edition. Buy.com has it and it qualifies for the $10 off coupon and free shipping. Check also with Other World Computing and Small Dog Electronics.

If you own a G4 Power Mac with a 2X or 4X AGP slot, your best option is the Radeon 9800 Pro Retail Edition (128MB). I included it in the test graphs above so you can see that it is almost as fast as the other Radeon 9800 models. It is also at Buy.com and also qualifies for the $10 off coupon and free shipping. Check also with Other World Computing or Small Dog Electronics or the Apple Online Store.

If you own a Power Mac with only PCI slots, you might want to upgrade to the Radeon 9200 Mac Edition. But read my report on that card first.
