Creating a 3D map for XNA ?
I am developing using XNA, a simple 3d tower defense game. I wanted create a 3d terrain. Here is how I am doing it:
fundamental element is a texture of grass, overlaid on a --> rectangle / cube ...( not sure about this)
These elements are much smaller than the entire game screen. Some equi-spaced elements are filled on the game screen with some randomly generated z values.
others need to interpolate between the z values.
Now the question is how to :
Actually implement it. method 1 is to have each element be completely straight, with normal in y direction, and vary z gradually. method 2 is have the rectangle/ cube surface tilt. If I do method 1 it might look pretty shabby. using method 2, I don't know how to get the surface z value at all the points, on the eventual terrain, which moving enemies will walk on / towers will be placed on.
Any help is appreciated. Thnx.
