geometry.following

Read a column of a closed run one place on: element i of the answer is element i + 1 of the column, and the last element reads the first. The next point round a ring, for each point of it.

Inputs

• values (Column or Field). The values read, the elements of one closed run in order.
• count (Number). How many elements the run holds.

Outputs

• values (Column). The column shifted back one place, wrapping at the end.

local ring = g.geometry.profile({ profile = g.curve.circle({ radius = 1, segments = 8 }) }).ring
local nextPoint = g.geometry.following({ values = ring, count = ring.count })
