Hello Karsten
thanks for the prompt response, but perhaps I did not explain
well
It is clear that using a formula can
to influence the formation of the surface ...
even if as in this case very " brainy " ;
but what I wanted to achieve is that simply by
the changes were driven by the position
of a point we call " Attractor ";
the variation of its cordinates, you'll have different distances
from the points of the grid ..
therefore taking advantage of the variation of this
parameter I want to vary the surface
That's why I think it is necessary that idx select
maintaining the incoming structure, and therefore also the output
of data relating to the points ....
I hope you can take action
Have a nice day
