Re: [osg-users] Texture2D non power of two and TextureRectangle
Hi Robert, I tested 2.8.2-rc1 with Texture2D and NPOT hint false and it is fixed.

Re: [osg-users] Texture2D non power of two and TextureRectangle
My mistake. It does also support ARB_texture_non_power_of_two. Robert Osfield mentioned a bug fix related to NPOT with 2.8.2-rc1 which may fix it. Thanks Jason Daly wrote: Patrick Shinpaugh wrote: That fixed it and likely the same would be required for the NPOT texture2d. Actually, no. NPOT textures still use normalized texture coordinates (0.0 - 1.0). I'm not sure why they're not working in your case. You said your card supports the *_texture_rectangle extensions, but does it also support ARB_texture_non_power_of_two? --"J" ___ osg-users mailing list osg-users@lists.openscenegraph.org http://lists.openscenegraph.org/listinfo.cgi/osg-users-openscenegraph.org -- Patrick Shinpaugh Virginia Tech UVAG System Administrator/Programmer 540-231-2054 ___ osg-users mailing list osg-users@lists.openscenegraph.org http://lists.openscenegraph.org/listinfo.cgi/osg-users-openscenegraph.org

Hi Patrick, Could you try the OpenSceneGraph-2.8.2-rc1 as one of the bug fixes was related to mipmapping and non power of two textures. Robert.

That fixed it and likely the same would be required for the NPOT texture2d.

I have no experience with NPOT Texture2D, but... if you are using TextureRectangle, be sure to provide tex-coords in pixel-space, not normalized tex-coords.
