What is Digital Field of View?

Digital Field of View is a method of determining Field of Vision based on Digital lines. Geometrically, all objects are considered to be diamond shaped, and the source diamond can see the destination diamond if there is an unobstructed line connecting them.

Advantages

  • Symmetric field of view.
  • Completely artifact free.
  • O(N2) algorithm available.
  • More permissive than Permissive Field of View.
  • It is easy to check by hand whether there is a digital line connecting two points.

Disadvantages

  • Nobody understands it yet.
  • Could be too permissive.

How do I implement it?

What games use it?

None, yet.

What libraries implement it?

None.
