AS3 Perspective Texturemapping

October 19th, 2005

This is the first step of a long journey. The example parses 3ds (3dmax) files and renders the scene pixel by pixel with a 'real' zBuffer for exact z-Sorting and a simple distance shading. There is a lot of space to increase performance. The most problem is drawing the pixels on the screen. The calculation of 236 faces connecting 190 vertices while clipping at the front plane is no performance problem. Commenting out the setPixel row, increases the FPS to 120.

Note: This example requires FlashPlayer 8.5

    today I was thinking when it will be available first AS3 example to parse some 3D file format and render :) and it was after few hours.

    Andre, respect :)

    Hey,

    Did you try the optimize=true compiler option to see if it has an effect? I’d be interested to see!

    wow that’s just insane André — do you parse the 3DS at runtime in that example or do you first convert to some sort of XML format?

    I’ve loaded the 3ds file as a binary into the URLLoader and parse it in runtime. This is really work, I don’t want to do :)
    But I could imagine, that will have a lot of parsing classes for several formats in future.
    Cannot wait for a swf-parser and swf-builder(!).

    Andre, can you share sources with us? :) It’s great example, and we can learn new AS3 from your example

    Yes, of course I will. Before I have to clean up the code. It’s horrible :)

  9. Franto Says:

    Sure :) Everyone knows, that code in test swfs, examples it’s not clean :) Anyway, not clean up code is better than nothing :)

    How the hell you got that out of Flex 2 I may never know. Could you try changing the bitmaps out with a cubic panorama? If I’m not mistaken you’ve invented the worlds first full 3D flash panorama viewer. In which case I’ll be a very happy bunny.

    If you havn’t got any cubic panorama pictures I’ve uploaded some here…

    Andre, your demo here worked in player 8.5 alpha, but it doesn’t work in player 8.5 beta!

    I hope that can be fixed with a simple recompilation…

    I cannot find the sources of this sample. Did you publish it yet??

    P.D.: Seems AS3 is as fast as Java!?!?! Incredible.

    It seems like you should have kept this new theme closed-source until a couple of weeks before the 5.0 launch… (don’t know if that was possible at all?) However, I definitely feel it’s not drupal that made a mistake here, but the wordpress team.
