extend

Clamps coordinates around an SDF result, which causes their edges to be extended infinitely along each axis.

Parameters

• Enable:
• Center: The center position around which the coordinates are clamped.
• Size: The size of the region outside which the coordinates are clamped. Within this area, the SDF will behave as it normally does.
