Detailed Description

Represent a 3D polygon as a collection of closed rings, each of which is represented by a FLine3. The first FLine3 is the 'outside' ring, any subsequent FLine3 are 'inside' rings, which are holes.

In most usage, there should be a consistency in the vertex ordering: the 'outside' ring should be counter-clockwise, and the 'inside' ring(s) should be clockwise.

void FPolygon3::Add

(

const FPoint3 &

p

)

void FPolygon3::Mult

(

float

factor

)

Multiplies (scales) all the coordinates of the polygon.
