    That looks good. You did that?


    I don't understand the term culling. It is used in print for subjects around procedural terrain generation, but I really don't get it.



    This is a frustum culling. Just like the render view, shadows also need a frustum culling or more advanced culling technique. For now i just use a basic frustum culling for each sun shadow split which is better than no culling. However i must find a better method for the terrain shadow.
