    Phoronix: Patches Published For Merging S3TC Library Into Mesa

    It's a slightly more interesting Sunday than usual. Besides working on a large file-system comparison (Linux 2.6.38 w/ EXT3, EXT4, XFS, JFS, Btrfs, etc) and new OpenBenchmarking.org features, there's an interesting development regarding the topic from earlier today about patented OpenGL support within Mesa. Not only has the email thread about integrating floating point textures support been resurrected, but another developer has now pushed patches that would integrate the S3TC texture compression library in Mesa while living behind the --enable-patented switch...

    What are the (software) products concerned by GL_EXT_texture_compression_s3tc? Are they an increasing number? Is it the only texture compression method/standard?

    First ask S3 (or whoever has the patent now). And in the worst case, here is another scenario: look at Blender; people bought it and opensourced it. Just a thought.

    I am not involved in mesa development, so I won't do what I am going to propose, but here is my simple question to everyone involved in mesa or whoever has the time:
    Did anyone even try to ask the patent-guys from S3 if it's ok to implement their technology in mesa??
    Maybe we finally get an answer and if so, it is either of
    • "yeah, no problem, as mesa is a free project" (so mesa can use it directly)
    • "we had a patent on this? uh, we don't care" (so mesa can use it directly)
    • "yes, but noncommercial only" (so mesa can use it directly, maybe via configure-switch)
    • "absolutely not, we sue you instantly and kill your families!1!!" (so licensed users can use it via libdxtn)

    Stop thinking+discussing too much and just ASK them!

    btw: Companies gather patents just to protect themselves from other companies with patents:
    Corp. A: "Hey B, you released some product and we patented technology X you use!1!!"
    Corp. B: "Well, but you use technology Y and we patented this"
    Corp. A: "hm, oh well... so we're even, carry on, we were only kidding"
    Look at early Microsoft/Sun/whatever... they simply used to be techies and did not care about patents. All this patent trolling occurred later.
    If you'd ask S3, we knew if they are like Evil Corp A or not.

    Yeah, but you can't blame the OpenGL spec for that.

    You can blame them for the floating point stuff, though.
