How to do picture in picture? (Corner map)

[SysRq2000]

Hi, I'm developing a 2D game using Direct3D. I need to show a transparent map window in the corner of the main window (see attachment), so the player knows where to go... How is this done in Direct3D?

It's up to you, really. Normally, you'd create two triangles that are Transformed and Lit already (as if doing a sprite) and draw whatever you want on a texture which would be applied to those triangles. You can set the alpha blend (and alphablendenable) to achieve a translucent effect.

Thanks. I thought it would be something like that... But since I'm pretty new to Direct3D I would like to see some example code or a tutorial. Do you know where to find any samples related to this subject?
