Maxon releases 64-bit Cinema4D for Windows only

updated 04:00 pm EDT, Wed May 18, 2005

64-bit Cinema4D

Maxon has released a Windows-only 64-bit version of Cinema4D, its high-end solution for modeling, animation, and rendering, and said that a 64-bit computing is . "Most notably, the Cocoa and Carbon GUI application frameworks are not ready for 64-bit programming. In practical terms, this means that the 'heavy lifting' of an application that needs 64-bit support can be done by a background process which communicates with a front-end 32-bit GUI process via a variety of mechanisms including IPC and shared memory."

    GUIs dont need 64 bit

    yeah, the fact that there are no 64 bit menus or buttons is a real deal breaker. Since when do you need a 64 bit pointer for such stuff?! Use the 64 bitness for your own stuff, don't try to say that OS X isn't 64 bit. If your code requires it, it's there. Lame excuse by Cinema 4D.

    No benefit

    frankly there would be no benefit in making most applications 64-bit on OS X. The speed gained from going 64-bit on windows has nothing to do with the fact that it is 64-bit. It's that the software can use the new registers and new instructions that are only available to 64-bit processes.

    I want my 64bit GUI !!

    Man, this just stinks. I mean, why can't we have a 64 bit user interface like Windows does. More bits = better, right??

    Sounds like lazy-a** programmers getting kickbacks from Microsoft spreading FUD to me... FUD FUD FUD.

    Standard (32-bit) OS X Carbon or Cocoa front end, 32- or 64-bit back end Unix application, and you've got an app that'll run on any OS X hardware... just like Apple tells you to write.

    Tiger's main point

    At least, from my point of view, was that it'd allow a larger memory space. The rest of the new features weren't compelling to me.

    The benefit is real...

    ...C4D PC 64-bit on actually renders faster than the 32-bit version.

    A PC (AMD processor)that used to get a Cinebench score of ~350 now gets a score of ~440s just by virtue of a 64-bit Cinema. That is ~25% increase and in that is huge.

    Macs CPUs will never catch up in regards to 3D performance and apparently Apple is solely to blame for this.

    64bit GUI?

    Hey, if you really want to make your GUI run slower, use 64bit data structures for all of your GUI objects! Talk about filling up your cache with useless pieces of information... sheesh. There's no reason to go 32bit in the GUI -- other than another upgrade treadmill inspired bullet point on your product's feature list.

    RAVH you are missing...

    RAVH you are missing an important point.

    The reason that the 64b version of C4D is faster is not a result of it using 64b addressing [1] but because on ADM/Intel hardware when you are operating in 64b mode they allow well over twice the number of registers that a software engineer and/or compiler can utilize (among other changes). Basically they are using the 64b mode as a way to break away from the limits that have long existed in IA32 (x86).

    In the case of the PPC ISA it was designed with more registers, etc and for 64b addressing from the beginning and no 64b mode exists. You don't get any gains like you are seeing on AMD/Intel because those gains already existed. So using 64b addressing when not needed you can adversely affect performance (since no gains are hiding those losses).

    [1] Unless you are actually working with a data set larger then allowed for under 32b mode and on a system with sufficient RAM.

    shawnces is 100% right

    "PC 64-bit on actually renders faster than the 32-bit version."

    That's because IA32 (the 32-bit Intel architecture) is crippled by 25 years of bad design, all the way back to the original 8086. AMD took advantage of going to 64-bit mode to get rid of a lot of those mistakes, and only keeps 32-bit mode as a legacy emulated mode. So going from 32-bit to 64-bit on an Opteron is like actually upgrading to a new chip.

    Power PC doesn't have this problem, so there's no performance boost from going to 64-bit mode unless you're re-writing the app to take advantage of the larger address space or longer integer registers... and Win64 uses 32-bit integers most places so it doesnt actually get all the performance advantage of AMD64 it could, just to make it easier to port 32-bit apps to it.
