Here's a screenshot from Paradox's "Europa Universalis III." It's a strategy game in the vein of the Total War genre, with an emphasis on a real time aspect of the strategy.

What I'm wondering is how a map like that is rendered in directx/opengl. Do you imagine it's a model? An image with 3D faked? How do you think you could highlight the countries?

Simplest way? Yes, a model. Basically a bunch of sub-divided planes (representing each country) with some sort of height-map for elevation. If each sub-divided plane has its own material, you could change it at will during run-time.

I'd tend to agree. It would be straightforward to do that using a model with material states for each colorable region. Artists would have a simple flag in Maya or whatever other editor they use, programmers would have an array for the materials, pretty easy work. Edited by frob
