Minimaps in DirectX

Hi, how can I make a mini-map in c++ d3d9, I can think of something that involves lots of unnecesary drawing. Would it be better to not build a mini-map engine and just draw a scaled version of the world map myself and then just use that?

The book Programming Role Playing Games 2nd Edition uses a stripped down version of your levels. Deleting all unnecessary polygons and textures, and saving them as a seperate model. Of course, in the book they are building a map that only displays areas you've been to before. For a more simple version, I'd imagine a 2d bitmap might work just as well, so long as the scaling is known.

I use a texture to cover the level. 1024x1024 is usually sufficient space. I generate the texture when loading the level, but you can also have your artists draw the map texture.
I then overlay "live" objects using sprites (enemies in radar range, etc).

Oh, I'll look into tht. I figure overlaying live dots/symbols would be easy, but I imagined doing something like redrawing 1000s of tiny textures every frame
