I assume by algorithms you mean like line drawing, scaling, rotation, etc.

There are several articles on this site which are about DirectDraw. DirectDraw lets you access the pixel data directly and sounds exactly like what you''re looking for.

There is no function in DirectDraw like DrawLine(), you have to impliment it yourself. If you get how to draw pixels and use directdraw but need more help with algorithms your professor should be able to provide assistance or point you in the proper direction.
