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.
