LavishNav:Point (Region Type)
Contents
Introduction
What is a Point?
A point is a location with zero size in any dimension.
Point Behaviors
Containment
A point contains another point only if it is the same exact location. For example, a point defined at 0,0,0 contains a given point only if it is also 0,0,0.
Nearest Point
The nearest point (and only point) within this region to any given point is the defined location of the point. For example, the nearest point within a point defined at 0,0,0 to a given point at 1,1,1 is 0,0,0.
Center Point
The center point (and only point) within this region is the defined location of the point. For example, the center point of a point defined at 0,0,0 is 0,0,0.
Point Characteristics
Points are descendants of the base region type. Any characteristics of the base region type may be applied in addition to the point-specific characteristics described below.
Point-Specific Properties
- X
- X-coordinate. Defaults to 0.
- Y
- Y-coordinate. Defaults to 0.
- Z
- Z-coordinate. Defaults to 0.

Examples
Example AddChild
; This code creates a point region at point 1,1,1. It also uses automatic name generation. LavishNav.Tree:AddChild[point,"auto",1,1,1]
Example XML code
<Point Name="Banker"> <X>1.234</X> <Y>2.34567</Y> <Z>3.14159</Z> </Point>
