    Mesa Now Supports A Bit More Of OpenGL 3.0

    Phoronix: Mesa Now Supports A Bit More Of OpenGL 3.0

    While some Mesa developers spent some time this weekend investigating WebGL issues in open-source drivers as noted by Firefox developers, Brian Paul and others have been tackling support for some new OpenGL extensions...

    The support for compressing using s3tc has not been implemented yet. In other words, r600g can not make use of libtxc_dxtn at this time.

    Oh wow, see, everything I've seen anywhere (including the Mesa FAQ) still points to http://homepage.hispeed.ch/rscheideg...3tc_index.html (hence my confusion).

    Okay, so it's a normal library. Might it be possible to write and distribute other possibly-encumbered extensions in the same manner? (I guess mesa just hooks it at runtime if the file exists?)

    Does it actually work with r600c? Did anyone get an S3TC app running correctly using r600c?

    I thought only r300g had it working.

    That's what I (and someone else has, too) was trying to suggest; it hasn't really been addressed yet. I'd like to at least try getting a Mesa with all the bells and whistles, but first I'd have to know where to find these things. I know agd5f has some patches in his tree (FP-related, I think?), but the rest of what exists and may exist in the future....

    @droidhacker & @DeepDayze:

    What the fuck, guys, did you even read the quoted text? It defines "open standards" as technologies that are (a) free to implement and use and (b) formalized by committees that are open to outside participation.

    According to this definition, HTML is an open standard, whereas H.264 or DirectX aren't. OpenGL falls into a gray zone, as it contains a few parts that are not free to implement.

    How the hell does this translate to that stuff you said?

    Yay for math being patented.

    Everyone needs to help spread the word to fight patents, and I really wish companies would join together to do so as well. And no, the Open Invention Network doesn't count, because it's just a patent pool, and that simply reaffirms patents. They need to be fraught against, not reaffirmed.

    That's quite the way Microshaft does things. They don't want their customers to have free choice
