Transform3D#lookAt() に悩んでいる遠藤です。

Java 3D 1.1.1 が出ているのは知っていたのですが、どこがバグフィックスされているか
詳しく調べてませんでした。

こちらによるとこんなところが直っているようです。

>   * ReadRaster does not clip to screen correctly 
>   * MediaContainer node cloned improperly 
>   * SwitchValueInterpolator needs to handle firstChild > lastChild index 
>   * Font3D tessellation not affected by PointSize in 2D Font 
>   * Compiles of nested BranchGroups consumes more memory than single root compile 
>   * Back clip distance in Clip node not scaled correctly 
>   * SceneAntialiasing setting of PREFERRED is ignored 
>   * Geometry Collision does not implement points/surface, line/line, or line/point 
>   * Java 3D cannot handle more than 64 lights 
>   * Cached eye position not set in compatibility mode 
>   * Cached transforms not set in compatibility mode 
>   * Region of Influence/Scope changes to Light/Fog doesn't effect static objects 
>   * Shape3D memory not freed when unassigned if associated appearance object is live 
>   * Java 3D classes and threads are not cleaned up and cannot be unloaded

>   * getBounds returns null for non-live scene graphs 
>   * wakeupOn fails to register a condition when called with the same reference twice 
>   * Collision does implicit conversions of bounds types 
>   * PathInterpolator's setKnot method does not validate inputs 
>   * Lw3d loader loses textures after pressing the reload button on Netscape 
>   * Sound performance on native threads is bad 
>   * Not all physical coexistence center policies are implemented 
>   * HMD mode not yet implemented 
>   * SceneGraphCycleException checking needs to be turned on. 
>   * Occasional spikes in Doppler calculation causes wild exaggerated pitch shifting 
>   * Filtering causes loud, sweeping resonance to be added to most sounds 
>   * Cross-talk cancellation for sound playback in not implemented 
>   * setReverbDelay(null) of AuralAttributes return incorrect value 
>   * HEAD_PREDICTOR and HAND_PREDICTOR policies not implemented 
>   * Geometry-based picking is not supported for CompressedGeometry. 
>   * Geometry-based picking is not supported for Raster 
>   * Geometry collision not supported for compressed geometry 
>   * Region of influence is not working properly for lights and fog 
>   * Multiple sample channels are not always synchronized when started 
>   * GMatrix SVD does not work correctly for some cases. 
>   * Java3D does unneeded redraws for window events 
>   * Loading HTML page or Java 3D applet while sound is playing may cause exception 
> 
> Utility Bugs 
> 
>   * ObjectFile Loader material properties support needs to be expanded 
>   * FourByFour generates SecurityException when tyring to write out the high score file 
> 
> 
> Solaris-specific bugs 
> 
>   * The 8-bit TrueColor colormap may not be loaded on an 8-bit frame buffer running CDE 
>   * This isn't Java3D-specific, but warnings of the following form occur on some Solaris 2.5.1
>     and some Solaris 2.6 systems when running any Java program with JDK1.2. 
>       Font specified in font.properties not found
>       [-b&h-lucida sans-medium-r-normal-sans-*-%d-*-*-p-*-iso8859-1]
>       Font specified in font.properties not found
>       [-b&h-lucida sans-medium-i-normal-sans-*-%d-*-*-p-*-iso8859-1]
>       ... 
>     This problem can be fixed by installing the optional ISO font package SUNWi1of. 
> 
> Windows-specific bugs 
> 
>   * Bug in Symantec JIT causes the GearBox example to render incorrectly. 
>   * Symantec JIT issues warning when running FourByFour example
