instances.sources (procNode)

The geometries a population stands, in the order the set was made: the ones given, else the ones the points carry. A set from instances.variants, instances.pick_random or instances.pick_by_attribute lists its sources in its detail's labels.Mesh; a set from instances.on_points carries its one source as every point's Mesh. Points that list none and carry no Mesh record are refused.

Inputs

• instances (Points). The population whose sources are read when none are given.
• sources (List<Geometry>, optional). The sources, when the caller holds them. They are answered as they are.

Outputs

• sources (List<Geometry>). The geometries, in the order the set was made.

local set = g.instances.pick_random({ points = g.points.grid({ countX = 2, countZ = 2 }), sources = { g.mesh.box({}), g.mesh.sphere({}) } })
local listed = g.instances.sources({ instances = set })
