    Lightbulb Triangle/Other shapes Algorythems....

    I have the basix of my graphics API for DOS put down (Called: DosGL) but I am still learning math, so I would really appriciate some algorythems to draw rectangles (I can do that perfectly centered, but with rotation/points not being perfectly inline with each other?), Triangles, "Polygons", and maybe even just lines.

    Here is a basic outline of what I have so far...

    1.) It uses double buffer with arrays of bytes for the pixels (1 pixel = 1 bytes), but will soon turn to 3 byte integers for hardware independance.

    2.) Shapes are presented to rendering algorythems in lists of verticeis.

    Thanks a lot, SPH

    P.S. If you haveany other Q's just AIM or EMAIL me, or just reply to this post!

    What kind of math are you using to draw this? Trig? Geo?

    The use of "GL" in the name of a graphics library is trademarked by SGI.

    If you you planning on distributing this, you probably want to come up with a name that does not include "GL", just so you can avoid the hassle down the road.

    They've threatened legal action against at least 1 use of it in recent memory.
