JRubyでJava3D その１

一先ず、java3Dのチュートリアルの「HelloJava3Da.java」を
強引にjrubyで書き直してみたが、問題なく動いている。

うい、結構使えるかも^^

でも、もう少し綺麗に書かないと、なんか気持ち悪いコードになってしまった。
後、jruby特有の記述があるみたいだけどいまいちその意味がわかんないから
ソースとサンプルで動作確認中

HelloJava3Da.rb

require 'java'
include_class 'java.awt.BorderLayout'

include_class 'com.sun.j3d.utils.universe.SimpleUniverse'

include_class 'javax.media.j3d.Canvas3D'

include_class 'com.sun.j3d.utils.geometry.ColorCube'

include_class 'java.applet.Applet'
MainFram  = com.sun.j3d.utils.applet.MainFrame


applet = Applet.new()

border = BorderLayout.new()
applet.setLayout(border)
config = SimpleUniverse.getPreferredConfiguration()

canvas = Canvas3D.new(config)

applet.add("Center", canvas)
simpleU = SimpleUniverse.new(canvas)

simpleU.getViewingPlatform().setNominalViewingTransform()
branshG = BranchGroup.new()

branshG.addChild(ColorCube.new(0.4))
simpleU.addBranchGraph(branshG)

HelloJava3Db.rb

createSceneGraph関数に処理を記述するよう変更

  rotate.mul(tempRotate)

  

  objRotate = TransformGroup.new(rotate)
  objRoot.addChild(objRotate)

HelloJava3Dc.rb

一先ずrotator = RotationInterpolator.new( rotationA, objSpin )でコンパイルエラー、原因不明＊A＊

ArgumentError: wrong # of arguments(3 for 1)

jruby-1.0無印だと問題なく実行できました。バグだったようです。

require 'java'

    rotationA = Alpha.new(-1, 4000)

    

    rotator = RotationInterpolator.new( rotationA, objSpin )

    

    bounds = BoundingSphere.new()

    rotator.setSchedulingBounds(bounds)

    objSpin.addChild(rotator)

    

    return objRoot

HelloJava3Dd.rb

HelloJava3Dc.rbと同件のエラー。
どこが間違ってるんだろう？

/jruby-0_9_9/src/builtin/javasupport/proxy/concrete.rb:6:in `new': wrong # of arguments(6 for 1) (ArgumentError)

こちらも同様です。＾＾；
