dist = 1000000 # Start with a large number
# Find the smallest distance
attractors.each { |apoint|

dist = dist_calc if dist_calc < dist
}

end
end
As you can see in the last few lines of code, this scaling transformation uses the syntax
that allows for different scale factors in each dimension. Because the panels are oriented
with the y direction (the components’ green axis) perpendicular to the wall, all other scale
factors remain as 1.
