I once did "zooming and panning" of pixel graphics using SDL. Worked nicely.
For your project supposedly having the graphic card construct the visible part of the polygons in realtime seems more appropriate. I suppose this can be done by SDL, as well.
(SDL is a user friendly layer between the application and either of DirectView or OpenGL.)
