Hi Dirk, thanks for not having let me down, I was getting a bit desperate. But your last mail gave me the solution. It's so stupid, you're gonna be deceived... It's just that I was creating a way too big 3D image, as I didn't understand the fact that you don't have to provide a power-of-two-sized square image (well here, it's a cube image...), but just a power-of-two-sized image. I didn't realized that 512*512*512 makes a 134 MB image that, I presume, OpenSG tries to load into the graphic card. For the most recent graphic cards, maybe that's ok but apparently not for mine. Anyway that was such a loss of space. Now with 512*64*32, it makes a 1 MB image that the graphic card loads perfectly well. And it works, I can display the content of this texture with a sampler3D in my shader, at last! You can be relieved, it's not a bug in OpenSG. Now, I hope you won't see me too soon in this mailing list ;)
Thanks again!
