BItmaps

[Judith Mortimer]

Can I use Opengl to display existing bitmaps (such as map tiles) and if so how?

Hi Judith,

Im from staffordshire as well!

Ive found the best way to display bitmaps is to use them as a texture on a polygon, so for example you create a square polygon the size you want the bitmap to be, then map the texture (bitmap) to the polygon.

If you look at Nehe's texture tutorials on
http://nehe.gamedev.net/opengl.asp

You should get the basic idea.
