arcCenter2Point()

Synopsis

Returns the center point of a circular arc through two points p1 and p2, where the arc is on a plane normal to the vector normal. The boolean onRight? is used to discriminate between the two possible choices -- True selects center point to the right of vector p1p2 when the arc is viewed directly.

Syntax

arcCenter2Point ( p1 As Point, _
                  p2 As Point, _
                  radius As Number, _
                  normal As Vector, _
                  onRight? As Boolean ) As Point 

Argument	Type	Description
p1	Point	one of two points on arc
p2	Point	one of two points on arc
radius	Number	radius of arc
normal	Vector	defines the plane of arc
onRight?	Boolean	used to discriminate between two possible choices for arc

Example 1

Using a rule to define all the arguments

Rule centerPnt As Point
    Dim p1 As Point = point(0,-2,0)
    Dim p2 As Point = point(0,2,0)
    Dim radius As Number = 3
    Dim normal As Vector = vector(0,0,1)
    Dim onRight? As Boolean = True

    Return arcCenter2Point(p1, p2, radius, normal, onRight?)
End Rule

Evaluate the rule above
