how can I implement the Bresenham midpoint alogrithm for scan converting
horizontal and vertical lines, and lines with slopes of +/- 1?


Thanks in advance~

i would google for it or ask in comp.graphics.algorithms... or read the 
faq of comp.graphics.algorithms...

In OpenGL? The line algorithm depends on the
driver...

Why would you want to implement a line drawing algorithm in OpenGL? It
already can draw lines.

You might want to do it e.g. for a homework assignment. The first programming
assignment in the intro graphics class here is to write a small OpenGL Paint
application in that uses Bresenham for its line-drawing.

That being said, people probably shouldn't be asking for their homework to be
done by others on NGs. :-)
