This is a really interesting and encouraging finding. Makes me wonder
if an open source driver might be possible under WIndows as well.
I would just love to get open source OpenGL drivers to a point that
they match the proprietary ones on all platforms, once you get to this
point there is no turning back, the open source development model will
just outpace the proprietary solutions in terms of features and
stability.
Both ATI and Intel have already published lots of specs on their
hardware, and Intel and ATI open source drivers are under development,
but it takes time to get a fully operational driver in place, so we do
need to be patient. It's good to hear of success with the Intel
drivers already. If only NVidia would follow suit and be more open
about their hardware then we'd have potential for OpenGL drivers to
all come out of hiding.
An aside from this is the interesting work being done a Gallium3D
http://www.tungstengraphics.com/wiki/index.php/Gallium3D
Hopefully this will help spur on the efforts on developing open source
drivers across platforms. It also adds another possibility in that
it's rendering API agnostic, so potentially we could even write
directly to Gallium3D rather than the OpenGL lib on top of it. This
is rather a leap though... Gallium3D needs to become successful first,
we need to develop the ability of the OSG to have multiple rendering
backends... lots of if's and but's... but we given a bit of patience
(like several years worth) perhaps both the Gallium3D and OSG will
someday be ready to dance to together.
Robert.
