Re: [Mesa3d-users] PocketPC support

[William G. <Wil...@la...>]

Pretty funny, I also work on Volume rendering on PocketPCs!
I am interested in any OpenGL and/or volume rendering stuff related to=20
Pocket PCs.
The fact about Mesa on PocketPC is not the basic operations of drawing
in a buffer. The problem is that PocketPCs do not have a FPU. They are
really slow at computing floating points.
Did anyone work on fixed point implementation?
