I'm developing a turn-by-turn navigation software for Windows Mobile using C# and .NET CF. I'm able to draw a 2D maps by drawing lines. My problem is I would like to get a 2.5D map like in the picture. I tried non-affine transformation on the 2D rendered image but it is too slow for the Windows Mobile device we are targeting.
