Edges are soft here b/c light source is not a point
It is possible for a point to see part of the light so there is an element to light intensity (for a constant size area) in the visibility function.
In this case only two possible values, 1 and 0
There will be a penumbra caused by an area light via the occluder.
each point can be 1 or 0
1 or 0
