AS3: Parsing .3ds file – Octopus

Sobota, November 26th, 2005

If you're new here, you may want to subscribe to my RSS feed. Thanks for visiting!

Yes, it’s awesome :) In AS3 you can just get .3ds file from 3d max, parse it, and draw it on screen.
You can see it on example .3ds file – Octopus. There more the 16000 faces, and it is rendered in less then 200 ms on my machine :)

Source code is dirty and it’s part of my AS3 project FlashLife, which will be open source, so you will have source available in some time, but I can not say now, when. It is in early state :)

Enjoy.

    I think your timing is incorrect. For me, it takes about 2 to 2.5 seconds to render. however, adding up all the traces, the supposed total is only 302 ms.

    The output I get:

    Hi David,

    I know there is something strange, but not only in this movie. More times i have little time intervals, but rendering to the screen takes longer. Maybe because all is done in 1 frame :) It is not optimized. But timer values are correct, do not know why it is so long to reender :(

    How you start it? reading the 3ds-file as binary code? connection to a php? i have started a ase-reader so i get a xml from a ase, but using 3ds directly would be much more nicer.. (right said? sry my bad english..)

    Its really nice to see, whats all possible with as3.. but a friend of mine will be lost only using as3.. he always did the design-part in our projects.. well i think, he has to lern a little programming now.. ;)

    hi0b> your friend shoul wait for flash 9 :)

    parsing is easy if you know 3ds file format, just dynamicaly load it as swf, or image, onComplete just get ByteArray from it, and just parse ByteArray accordinf 3ds file format :)

    sounds really easy.. i think in the future we will see more examples of importers, for which i use php right now.. i have also seen examples of encoding pngs and jpegs..

    good to see, that adobe pushes flash.. under macromedia, flash already reached the limits.. ;)

    Whether really it is useful?
    Illustrate for 3ds max can 3d animation export in swf format.
    For more powerful & interactive 3d we have Director?!
