Bug in TextureIO.newTexture without Mipmapping?

Hello,

I have a problem : If I create a new Texture with com.sun.opengl.util.texture.TextureIO.newTexture and do not use mipmapping, I get a blank cube (which is textured if I’m setting mipmapping=true).
My texture has power of 2 (256x256 pixels).

If I create the Texture with TextureIO.newTextureData and setting the texture for the texture target manually, it works.

Here is my little test programm :

and my test texture image :

What is wrong with my code???

P.S. My graphics card has the following data :

Renderer : Matrox G400

Your test case works fine for me using the TextureIO.newTexture() factory method both with and without mipmapping. There’s probably something going on with your OpenGL drivers which doesn’t surprise me since you have a Matrox card. See whether there is a more recent driver release available, or just toss your card and get something (even a cheap one) made by NVidia.

I was banging my head against the wall playing with TextureIO for maybe the first time (I think I tried it out a few months ago, can’t remember :-), until I came across this thread. I turned mipmap to true, and presto, everything works now. Before I was getting a blank square.

For my purposes at this time, I really don’t need mipmapping, I am doing a 2D project.

I am using Ununtu linux 6.06.
Nvidia GeForce MX 4000
nvidias kernel module found in the ubuntu repository precompiled for a k7 processor.
The kernel is also precompiled for a k7.
beta 5 of jsr231.

The function is this one.
TextureIO.newTexture(File, boolean);

I may throw this over to my laptop later tonight and test it on an ati with dri running Ubuntu 5.10.

I am not saying that this is not a driver bug, I am saying it is a little more broad than the matrox.

Thanks

Greg

If you are running into a problem could you please provide a small and self-contained test case including the associated image which fails?
