Quantize x,y values, using other spread as root?

vvvv beta question
1

Hi people,

i´m looking for a way to resample or exchange some x,y values in to other root spread (a circular spread for example), choosing the nearest points to this spread.
i´ve checked the kalle´s quantize (value) but it quantize the values into a cartesian grid.

any accurate way to do this?

Thanks

Ari.

sounds like plug to me… think you have do is evalute distance from each point of old spread to each point of new spread and then like move 2 closest dist…

the fact it’s not friendly solution specially if your spread is huuuge
hmmm need to check some archives think i had something for that…

couldn’t resist to wrap this into a module:

Now there is SiftNearmost (2d)
