Moving wireframe 3d minimap

Hi!

I would like to create a 3d minimap like the one which is in the Hostile Waters: Antaeus Rising. If we analyze the original we can make these requirements:

• minimap should move (not just a circle mesh and change its points with continous terrain polling in the down direction)
• texture should be wireframe with transparency
• should contain war of fog

I think a circular terrain mask on a second terrain object would be fine. Do you have any hints how can I start it?

 

I haven't play the game, and i don't know what features it has.

But from the picture it looks like a wireframe representation of a height map of a terrain. I don't know what you are using for your terrain, but if you have a heightmap, then you should be able to achieve such a look.

There's alot of stuff here about fog of war here already if you look for it.

 

How can I show just a circle part of the heightmap?

 

The bottom/background?

GameObject->3D-Sphere scaled down in Y and added to the gui?

 

Not the bottom. I want to render that part of the minimap where is the vehicle.
