Points are a Sphere that Visually Represent a Point Coordinate in 3D Space. Polygons (Tris and Quads) Require these.

Creating and Selecting

To Create a Point simply click on the Create Objects button and Select "Create Point", it will also get added to a invisible "Point History" which contains up to 4 points.

This "Point History" is used in the creation of Polygons (Tris and Quads)

Holding Shift and Selecting a Point will keep the Previously selected points in the Point History. Selecting a Point without Holding Shift will Clear the Point History before Adding the new point in.

Colors (And what they mean)

Green is the Selected Polygon. This is the Polygon you are Editing. This will be deleted when you click the Delete Button or Press the Delete (Del) Key on your Keyboard.

Red is a Polygon in the Point History.
