Papervision3D: Happy New Year, Graphics3D Profile Rotation

Posted by james – January 1, 2009

Happy New Year
[Subversion Repo]

I have created a code repository for the ThreeDee Papervision3D extension.
    svn co https://iciifs.com/svn/ThreeDee

Graphics3D now supports profile rotation around the z-axis.
Simply draw a curve using the normal Graphics commands.
Then call endFillSpin(degrees:Number = 360, steps:uint = 20) to create on object based on the rotated curve.

    Hi,

    I tried the give code but it doesn’t work.

    I just changed “this.holder” to “this.scene” as it was giving error:

    1119: Access of possibly undefined property holder…

    Can you please help.

    Regards
    Saurav

    Hi,

    Can you please provide me with the complete source code for the above example.

    I think there’s some problem with the PV3D & threedee source code version

    Thanx
    Saurav

    Hey thanks for this great library!
    I’m trying to use the latest version from the repository and I noticed that linesPerCurve was removed? Now i se a public static var called segmentsPerCurve but if i set it to a value higher than 4 I get a runtime error… I need a better curve quality than 4.

    [...] Papervision3D的强大已经不用我多介绍，现在的FWA已经基本是3D引擎的天下了。除了自身所带的功能以外，大量第三方的辅助类库或插件也起到了锦上添花的作用，所以我把它们并作一条。做粒子效果可以考虑Flint，变形修改器可以用AS3DMod，ThreeDee提供的扩展功能也很不错。至于物理引擎那也很多，只是我目前还没有涉及，这里也不多说了。 [...]
