All, Clarification:
The stack trace I initially posted is misleading, as I was mistakenly calling ImageComponent2D.getImage, however even if you call ImageComponent2D.getRenderedImage you can see that the call gets delegated to ImageComponent2DRetained.getImage which assumes it can cast to BufferedImage. Exception occurred during Behavior execution: java.lang.ClassCastException: javax.media.jai.RenderedOp at javax.media.j3d.ImageComponent2DRetained.getImage(ImageComponent2DRetained.j ava:339) at javax.media.j3d.ImageComponent2D.getRenderedImage(ImageComponent2D.java:298) at MultiTextureTest.updateData(MultiTextureTest.java:362) My next problem is what can I DO with an instance of java.awt.image.RenderedImage (RenderedOp) if I can get one? It appears that BufferedImage is the only WRITABLE image anyway, so even if I get a RenderedImage back inside my updateData method how would I modify it? My previous code was using a BufferedImage and simply getting a Graphics2D from the BufferedImage and manipulating it. I am trying to use JAI to generate procedural BYREF textures, updated from within a behavior using ImageComponent2D.updateData. Is this a problem integrating JAI and Java 3D? Any thoughts, experience and guidance much appreciated.

All, I am using JAI to generate some procedural texture images and I am getting the following exception: java.lang.ClassCastException: javax.media.jai.RenderedOp at javax.media.j3d.ImageComponent2DRetained.getImage(ImageComponent2DRetained.j ava:339) at javax.media.j3d.ImageComponent2D.getImage(ImageComponent2D.java:275) Java 3D appears to be assuming that the image is a BufferedImage. It is a javax.media.jai.RenderedOp instance (which implements java.awt.image.RenderedImage). Is this a bug, or am I doing something wrong?
