All it does is apply model transformation matrix and pass through of texture coordinates.

There are two issues: 1. As was explained to me we need to have swtcl code in case we need to do software fallback for some unsupported feature 2. Right *now* we are doing only swtcl, as no acceleration for transform and lightning is being done.

Do you still see the same breakage with vertex buffer mode? The textures in
neverball are broken for me in immediate mode with the latest cvs.

The textures in neverball are broken for me in immediate mode with the latest cvs. No, I don't in fact, with vertex buffer mode it is mostly as good as before. The one difference I have noticed is that the first screen of pinball displays the background texture wrongly (half-width and repeated horizontally, and displaced and wrapped vertically), but if I get it to redraw it displays it correctly.

[R300] texture breakage
I did a CVS update on my Mesa and r300_driver repositories yesterday, and now texture handling is quite broken on the Radeon 9600 (AP) on the G5 powermac and on the Radeon 9700 Mobility (NP) on my G4 powerbook. The effect is quite strange; in pinball for instance, some textures are displayed really small and repeated, while others are larger than they should be and offset. I have put a couple of screenshots at: http://ozlabs.org/~paulus/pinball1.png http://ozlabs.org/~paulus/pinball2.png The previous version (CVS from a week or so ago) displayed pinball more-or-less correctly. Anyone know what's changed? Paul. --- SF email is sponsored by - The IT Product Guide Read honest candid reviews on hundreds of IT Products from real users.

Re: [R300] texture breakage
I have been busy lattly but i will check this friday or sunday. A quick review of commited things havn't give me a clue. This is more likely due to a change somewhere in texture upload or maybe with experiment on multitexture Vlad others have made.
