[Closed] assigning values to vertexes

hi,
my problem is a bit complicated but i’ll try to explain…

i want to know if max script can assist me in assigning values to vertexes based on interpolation between specific vertexes – for instance :
if i have a rectangle and i assign a value (color for instance) to all four corners , is it possible to automatically set the values of the remaining vertexes using linear interpolation.

the objects are more complex then a rectangle of course…

thanks in advance
