thanks for your reply
ok, it's easy with a primitive shape (sphere, cone)
texture coordinates are automaticly created
but how can i do that with a irregular geometry??
sorry if my question is stupid...
I understand how to use the textCoordinate with a
unique texture map onto a shape but not with a

It works nicely! I also found couple of good examples in java 3d tutorial.

Save your image to a file type that supports transparency ( .gif or .png ) -
set the area you want to see the background through as transparent, and then
try texture mapping with that image. Here's a snippet of code which might
help.

Time to buy a book I think Sagar.

"painting" the textures onto the shapes (there are several ways) instead of
having the CPU do it before sending the results to the graphics card.

Sam,
No you are right the filters do not alter the shape in any way. They work
by either using point sampling of neighbouring texels and using that colour,
or by interpolating among neighbouring texels, depending on which mode you
choose.

Well simply before you add the Scene to your ContentBranch of your Locale

I may
be misunderstanding your question, but you can just walk the scene graph after
the objects are loaded and use the "instanceof" java command to find
the shapes, their geometries and thier types.

I think you need to specify the coordinates manually for something like
that. I have seldom seen a time where the automatic tex coord generation is
useful. Generally the only time is when the geometry is procedural and you
can equate some mathematical mapping from your r,s to u,v.

I think the easiest way to do this to change the texture coordinates of each
cube face to reverse the image in the direction you want. If you take the
existing texture coordinates for each face and swap the coordinates for the
axis you want to reverse, that should do the trick.

these instead TextureLoader(java.net.URL
maybe.. possibly.. give it a try.

Exactly, as the internal BufferedImage has not been loaded (i.e. is still
null), a null pointer exception is raised when trying to resize the image to

That means the observer.checkimage has returned ImageObserver.ERROR
So either the image is not there/corrupted or your implementation of
ImageObserver is not
correct.

Hi Renaud,
Thanks for your advice, but unfortunaly it didn't work.
This is my code :
public void createAppearances()
{
Color3f black = new Color3f(0.0f, 0.0f, 0.0f);
Color3f deepRed = new Color3f(0.9f, 0.2f, 0.1f);
Color3f royalBlue = new Color3f(0.1f, 0.3f, 0.9f);
Hi,
a null pointer exception in texture loader often means it cannot find the
texture.
Try to use the constructor with an url like :
TextureLoader texLod0 = new TextureLoader(new java.net.URL
("file:sign1.gif"),
new String("RGB"),
this);
