Point
What it does
Point outputs a Collection holding exactly one point, at the position you set. The point carries a scale attribute, read as size by anything downstream that treats scale that way, such as an Iterator stamp or a scatter radius, and optionally a colour.
There is no input port and no distribution logic. It does not scatter and does not sample a shape or a Distance Field. It places one point.
When to use it
A single locator or null marking a spot in space, as an anchor for something else to read.
A hero placement: one instance planted by hand rather than scattered.
A seed primitive feeding Iterator or Stamp for topology-driven instancing.
A one-point Collection to test or drive an Attribute Assign / Edit chain without building a whole shape first.
Gotchas
Colour is off by default. No colour attribute is written unless Apply Color is on, leaving downstream nodes to colour the point without a stray value in the way.
Position, Scale, and Color are animatable. Moving or recolouring a Point over time costs no rebuild, so it is a cheap way to keyframe a single marker.
Worked example
Add a Point. Set Position to place the marker.
Raise Scale for downstream nodes (a Stamp or Iterator) to read it as a bigger instance.
Turn on Apply Color and pick a colour for the point to carry its own colour rather than being coloured downstream.
Wire the output into Iterator or Stamp to instance geometry at this location, or into Merge to combine it with other points.
