Detailed Description

This file contains indicator functions.

These return 1 if the given coordinates are inside, and 0 if they are outside of the defined set. Implemented are :

• Cuboid
• Circle

• Triangle

  The smoothIndicator functors return values in [0,1]. In particular there is an epsilon enclosure of the set, wherein the return values are smooth and do not jump from 0 to 1.

Boolean operators allow to create unions and intersections. They can be used for example for initialization of a SuperGeometry.
