Hello Corbin,
 Thanks for the advices. Of course the mesa GL implementation is a good doc source.
 Now, perhaps havent you fully read/understand the first post.
 The "GL2GX" driver (translating GL instructions to Wii GX ones) is already running on Wii. We can display a textured box with some dynamic lights as shown on the picture.
 I regret that your time period is not more immediate.
 I suppose that in one month, an opensource 3D engine would be ready to go.
 For example, here is a "non-openGL compatible"  engine :

 But thanks anyway, dont hesitate to link the post to your friend.
Kind regards

You might want to take a look at the various non-DRI drivers in Mesa. It
would be perfectly possible and fine to use GX calls inside a Mesa
driver, so that applications using Mesa's libGL would have their GL
calls translated into GX calls.

I'd be interested in getting involved with this in a few months.
(Perhaps over summer; one of my good buddies is a Wii enthusiast and has
a homebrew setup...) However, I've got Radeon work on my plate, so I
can't help too much right now.

I suggested the Glide driver because it looks a lot like GX in some
spots; however, reading any of the Mesa drivers might provide some
useful insights into how Mesa works internally.
