Two scalar fields - example

Example - 2 rods

Top code - standard 3D design

    Iterate all positions in empty vG

    - If position is closer to xy center than 20 :

          Create voxel

    - If position is closer to shifted yz center than 20 :

          Create voxel

Bottom code - design via 1/d type scalar field, 4D design

    Iterate all positions in empty vG

    Calculate 1/d scalar field no.1

    Calculate 1/d scalar field no.2

    Add both fields

    - If total field is less than a limit (0.05) :

          Create voxel

The result shows an organic blend of the two fields
