Thanks Phil,

LineArray and LineStripArray not rendering as nicely might be an issue depending how it looks.

Here's a code snippet showing our use of Texture2D:

    Texture2D texture = new Texture2D(Texture.BASE_LEVEL, getTextureType(new_image_type), current_image.getWidth(), current_image.getHeight());
     ImageComponent2D image2d = new ImageComponent2D(getImageComponentType(new_image_type), new_image, true, true);
     image2d.setCapability(ImageComponent.ALLOW_IMAGE_WRITE);
     image2d.setCapability(ImageComponent.ALLOW_IMAGE_READ);
     texture.setImage(0, image2d);
     texture.setMinFilter(Texture.BASE_LEVEL_POINT);
     texture.setMagFilter(Texture.BASE_LEVEL_POINT);
     tile.setImageComponent(image2d);
     TextureAttributes texture_attributes = app.getTextureAttributes();
     texture.setEnable(true)
     app.setTexture(texture)

I would have to determine the impact of not have the minification/magnification filter

We make heavy use of (From the original Java3D doc) for efficiency:

public ImageComponent2D(int format,
                        java.awt.image.BufferedImage image,
                        boolean byReference,
                        boolean yUp)

Constructs a 2D image component object using the specified format, BufferedImage, byReference flag, and yUp flag. The image class is set to ImageClass.BUFFERED_IMAGE.

Parameters:
format - the image component format, one of: FORMAT_RGB, FORMAT_RGBA, etc.
image - the BufferedImage used to create this 2D image component
byReference - a flag that indicates whether the data is copied into this image component object or is accessed by reference
yUp - a flag that indicates the y-orientation of this image component. If yUp is set to true, the origin of the image is the lower left; otherwise, the origin of the image is the upper left.
