: Nod. I was afraid of that too :-/. But maybe we can integrate Bresenhams
: line into this in some way ( <g> ) and get ellipses too ;-)
: But since it is all integer, it is a way to get the floating point library
: out of nano-X, which is good for a) space and b) performance.
There's no floating point in nano-X or MicroWindows.
The 3d graphics library that I added to MicroWindows uses floating point,
but it's entirely optional and none of the line drawing routines use it.
: Anyway, I suggest you take a look at SWAG. There's A LOT of interseting
: stuff in there - a lot of BS too unfortunately... I think the EGAVGA.SWG
: and GRAPHICS.SWG are what you need. Maybe you can get some idea's there to
: write other drivers too... It has some code for a 3840 color ModeX (hehe),
: it does this by storing the red value (1-15) on one page and the green and
: blue on the other page, and then perform fast page swapping...
:
Where is SWAG again?
