points.from_grid (procNode)

The cell centres of a grid as plain points: the cell layout leaves the detail and each point carries its own number as id. points.box and points.grid end here.

The points come in the grid's cell order, x fastest, then y, then z.

Built from: member writes on the detail and point domains, g.element.id.

Inputs

• grid (Grid). The grid whose cell centres become points.

Outputs

• points (Points). One point per cell, carrying P, the grid's cell attributes and id.

local centres = g.points.from_grid({ grid = g.grid.box({ size = vector.create(2, 2, 2), cells = vector.create(2, 2, 2) }) })
