[Mesa3d-dev] samples/sphere broken in last two weeks?

[Gareth H. <ga...@va...>]

One of the updates to the Mesa-3.4 codebase in the last two weeks seems
to have broken texturing in this demo app.  Software rendering with
standalone Mesa fails to texture the torus at all, and thus it's not
surprising that the hardware drivers also fail to texture it.  I just
updated with

cvs update -D "2 weeks ago"

which pulls in the code from directly before the tdfx branch changes
were added.  I'll create a diff of what's changed in that period and try
to track it down.

It doesn't texture with any recent version of Mesa for me.

It looks like a problem in texture completeness.  I'm digging deeper...

It's the ppm image loader.  I converted a .rgb file to .ppm but
the image size is read as 0 by 0.

I changed the program to read a .rgb file and it seems to work with 3.5,
though there's a texture coordinate problem in the rendering.

It's still not texturing with 3.4 though.

I've checked in a bunch of changes to this demo. It seems to work
fine with software rendering in 3.5 but still isn't working with 3.4.

The DRI tdfx-3-0-0 driver is having trouble with it too.

I'm not surprised, as the Mesa code on that branch should be what's in
3.4.  Should we just leave it as fixed in 3.5?  Should I even bother
looking into it at the moment?

We should fix it in 3.4.  If you don't beat me to it, I'll look deeper
on Wednesday.
