Hi there,

Does ATI support GL_ARB_texture_rectangle, and if it hw specific which chips do support it?
Is also the texture2DRect GLSL function supported?

Thank you in advance, lg Clemens

have a look on this:

That's just nVidia vs ATI bull****, if you can have a look on the good old meeting notes, you will see that ATI haven't vote for GL_ARB_texture_rectangle...

They care to that the doesn't expose the feature right.
On nVidia hardware check GL_NV_texture_rectangle or GL_ARB_texture_rectangle. On ATI hardware check GL_EXT_texture_rectangle ... that's stupid even more when this extension have been voted by the ARB.

nVidia doesn't do better, GL_ARB_vertex_blend never been implemented... Even if hardware have the capability anyway.

These last years seem more healhty on the political side, maybe because ATI have abandoned OpenGL for a while. Until it death?
