So after reading https://www.guerrilla-games.com/read/killzone-shadow-fall-creating-art-tools-for-a-new-generation (a guerilla games presentation on PBR) I noticed the Area lights as opposed to the standard Directional, Point & Spot lights in DirectX can produce very realistic shadows.
Now a lot of the resources online talk about it and what it is but there's not much regarding implementation. Some websites online say that it is just an array of lights but I don't think that's what it is.
Can somebody explain how I can implement this (and maybe with some code). If you could include any links to some good resources regarding implementation that would be great aswell.
