The Bulge texture is intended to be used as a bump map or a displacement map. It produces an area that is flat along the outer edges, and bulging in the middle. If this texture is repeated along a surface, it produces an effect similar to a skyscraper pumped full of air; the windows are bulging, but held in by the flat frames around their edges.

Aside from the attributes listed here, Bulge inherits many other attributes from its parent class, Texture2d.
