*in [Lib.point.modify](README.md)*

Allows selecting and adding values to points in 3D space via SDF Objects/Fields.
Similar to [SelectPoints].
Needs any SDF such as [BoxSDF], [ChainLinkSDF], [FractalSDF] as an input to select the points.
And any form of points such as: [GridPoints], [RadialPoints], [SpherePoints], [PointsOnMesh], etc.
