TextureLoader tex =
new TextureLoader( "earth.jpg", this );app.setTexture( tex.getTexture() );
If you need to modify the wrapping for S,T you can store the result of tex.getTexture() and call setBoundaryMode* before assigning to the appearance.
I hope work for you.
Sincerely,
Daniel Selman

Subject: [JAVA3D] Texture
I am trying to learn how to use textures.
I added the following code to my appearance:
TextureLoader loader = new TextureLoader("tex01.jpg", this);
ImageComponent2D image = loader.getImage();Texture2D tex = new Texture2D();
tex.setImage(0, image);
tex.setEnable(true);
tex.setBoundaryModeS(Texture.WRAP);
tex.setBoundaryModeT(Texture.WRAP);A.setTexture(tex);

When I try to run my applet with appletviewer, I get the error:
appletviewer pattern.html
java.lang.IllegalArgumentException: cannot set image in default texture

When I try to run it by just clicking on the html file, I get the error:

Error: in loading image

The "tex01.jpg" file is in the same directory as all the class files and the html file.
Anyone know what's wrong?
