mapper substitute


    Nov 17 2006 | 1:52 pm
    I'm trying to make a substitute for Tristan Jehan's
    mapper object, pending it's porting (I hope) to UB.
    What I have below works as far as it goes, but I would
    like it to generate a wider variety of curves, like
    mapper does. In particular, I want to be able to
    generate the 'inverse' of the curve. I guess it's a
    job for expr, but the maths is failing me.
    ( I imagine there is a Litter object that does exactly
    this, but as the UB versions are not yet available for
    non-pro users, I'll have to be patient ;-)
    cheers
