# UVPoint

A point in 2D space. This object lives in the Lua session only. Points are defined by numbers and cannot be defined with expressions. Mathematical operations can be done on points.

## Example

    -- Create a default 'UVPoint' at (0,0,0)

p1 = pf.UVPoint.New()

-- Assign values to each component of the point

p1.x = 1
p1.y = 1

-- Create a 'UVPoint' with number values

p2 = pf.UVPoint(2,2)

-- Determine the distance between two points

distance = p1:distanceTo(p2)

-- Some of the valid operators for 'UVPoint'

p3 = 2 * p1
p4 = p2 * 2
p5 = p2 / 2
p6 = -p2
p7 = p1 + p2
p8 = p1 - p2
if (p1 ~= p2) then
print(p1.." is not equal to "..p2)
end
