I wish I knew. I'm guessing it would be something akin to an abstract
factory of a sort. First I suppose there'd have to be a 3d maths library
implemented into boost. This is something that I can see the design of quite
clearly, and should be quite straight forward to get relatively right.
Even if that alone was created without a graphics lib it would be a big

It would indeed :)

The backends I would love to see supported are:
> OpenGL 1.5 / 2.0
> Direct3D 8.1 / 9 / 10, XBOX, XBOX360
> OpenGL|ES 1.0 / 1.1 / 2.0

Yeah, but I was not thinking of a fully featured 3d rendering library. More
like a subset of the various graphics apis. Like most of the basic
functionality. I don'k know how useful this'd be for the more "cool feature"
inclined 3d applications (games come to mind), but it'd be more then
sufficient for 3d app that do not require all the razzle dazzle that games
would. Like scientific research applications and visualization software

Could you add to this a bit. I'm not familiar with asio (I just spent a
little while looking at it), but like what'd be the key differences between
a toolkit approach and a framework one? A toolkit one would more closesly
resemble a utility library yes?

So if there was a boost graphcis lib, then it'd have to go through one of
the cross platform window frameworks? How about just a basic window object
that's just created for the graphics lib? Nothing fancy nothing extra... I'm
not really familiar with the topic though as I've only been doing win32
development when it comes to windowing systems.

Yeah, maybe we can manage to gather some ideas on how something like this
can be implemented.

Yes, that's exactly what I was thinking, basic functionality.

Do you have anything in mind of how something like this owuld look like?
