Creates a point attribute whose values represent how far they are from the input points.

Advantages over the distance metrics in Houdini:

1. Much faster performance (Even compared to the new surface distance feature in H16.5).

2. Surface based geodesic distance feature in addition to Euclidean distance (volume).

3. Ability to specify whether to limit radius.

4. Ability to have variable radius per input point.

5. Ability to normalize per connected surface separately.

6. More intuitive.

Falloff SOP

Creates a point attribute whose values depend on how far they are from the input points for a given radius using surface or volume method. It's very performant and works in real time even on high resolution models. https://www.patreon.com/animatrix
