Dear francois,

I did tried, but it seems to be an output of a single line with points on
it.

I go from 
position
(Global)>normalize>fval1(vectofloat)>ramp>floatovec>position(output)

thanks

cheers
herman

One way is to put a vopsop after a grid and use a Bias Vop or a Ramp Vop to
alter where the incoming X coordinate will be remapped to a different X. The
key is to first remap your X value into a normalized 0-1 range before the
bias or ramp and then remap it back.

Let me know if it's not clear and I'll go into more details.
