I come to a point where I want to implement shadows into my renderer, first I thought of simple shadow mapping of course, but in my case the camera is very restricted so properly there are other methods which provide better visuals.
So I have following camera restrictions.
- fixed height from the ground(maybe I allow zooming in)
- orthogonal projection
- fixed rotation(maybe not)
- isometric view(z:45° x:32°)
- user can only move the camera on the xy plane
- only sun as light
And if you think that shadow mapping is the best choice how do I calculate the view of the sun best. So I get the best results
