Rectangular Texturing Unsupported

Post by Troglodactyl »

Greetings all,

I've been trying the nightly builds, and find that in recent builds the minimap doesn't function on my system. A debug turns up that Rectangular Texturing is unsupported, and that without it radar will not be displayed. I'm on a laptop with onboard graphics (Mobile Intel 945 Express). Does anyone know of any fix for this? Or if it's likely that later builds or later releases will not require this?

Thanks for any help.

We require at minimum support for the GL_ARB_texture_rectangle extension to OpenGL. This is described here: http://www.opengl.org/registry/specs/AR ... tangle.txt

There is very little chance of this requirement being voided in the near future — the new widget code for example also makes use of this extension.

While it is — in theory, possible to work around it (by padding the texture with transparent pixels to make it a power-of-two) one has to ask why the driver developers did not do this in the first place. Chances are your GPU is just too old/slow for it to be implemented without a serve performance hit — henceforth emulation of it on our part would be little more than an exercise in masturbation.

Regards, Freddie.

Well, if such masturbation is easy for you then I recommend you get to work. O_o

Troglodactyl, have you updated your drivers? In my experience embedded chipset manufacturers typically don't update their drivers beyond the initial release, but I would suggest giving it a shot.

A wise piece of advice, a quick Google search yields: http://downloadmirror.intel.com/15605/E ... xp_gfx.htm

In the release notes there is a section on new features, the sole addition being:
1010359 - Adding OpenGL* extension, Texture Rectangle to OpenGL 1.5

Thank you all for your replies.

With the most recent drivers I still have the same issue, but as the driver release notes say, it should be supported. Any ideas for determining whether it's a system/driver bug or a game bug causing support not to be recognized?

Go and download yourself a copy of GL View (http://www.realtech-vr.com/glview/ ) and dump the output it gives. This will list all of the supported extensions by your card.

Texture rectangle support no longer required in trunk for the minimap.

http://developer.wz2100.net/browser/tru ... =5963#L553 — it already has — don't expect any quarter either ;)

Will still be a several months before it goes mainstream, however.

Nothing to be happy about for me.. I will have to go, if i can't see something i need to see.. When i can't play this Game anymore.. Only because of one Graphics Function.. My PC is only 4 Years old..

Well, let's see if we can't find a way to eliminate the need for the texture rectangle extension everywhere. It wasn't so hard for the minimap when I just figured out a good way to do it.

Currently this is apparently an issue with the FMVs also, I'm not sure where else. Is this likely to be changed in a future version? Thanks again, everyone.

Erm.... I doubt it, unless someone wants to add the code to fix that issue.
Pardon me, while I go strangle intel for not having that extension, even though, it really should. :scream:

Ok. I just started on C++ this semester, so I'm afraid it will probably be some time before I can contribute anything of value. :(
