I have to draw a 3D terain (polygon) using openGL and Tao Framework in C#. The problem is, i have never done such things before and i dont know how to start. I have my KML file and i wonder, how to read data or use coordinates, to draw a 3D terain of the path i've walked (or drove with a car).
Can anyoone give me any advice or help how to start making the 3D object of it?
The point of the program is, to create a 3D polygon which can rotate around, so i could see in 3D where i walked, if u can understand what i mean with that.
