    this is one of those questions that seems easy to answer... at first. Questions: Is this in 2D or 3D? Does the winding order matter (cw or ccw)? Do the end points define the complete semi-circle?

    In any case, there are quite a few steps involved in solving this one.

    You might want to take a look at the GLU specification. You can find it at

    It provides a simple implementation for drawing semi circles using gluPartialDisk.
