bulge

Go to: Related nodes. Attributes.

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.

Some uses for Bulge:

• Map a bulge texture to both the Transparency attribute of a shader, and through a bump node to the same shader, to produce a 3d window effect.
• Map a bulge texture to the Color attribute of a shader. There will be no apparent bulge created, but it will produce a tiled color effect.

uWidth, vWidth

Long name (short name)	Type	Default	Flags
uWidth (uw)	float	0.1
U Width and V Width delimit the area of constant value in the texture. If you think of the texture as as producing a window frame with a bulging window, then U Width and V Width control the width of the window frame in each direction.
vWidth (vw)	float	0.1
V Width. See the description for U Width.
