"Hi Mar, what's the function? I attached a file which creates a Nurbs surface from scratch from an f(x,y) function, and also a way to modify an existing mesh using that same function. -- David Rutten david@mcneel.com Seattle, WA"

Two variable function in local axis

This must be very simple but I really do not know how to tackle it.Well, I have a function describing a surface, so a two variables function that I would like to implement with local axis...That is to say, I have defined custom axis with three points and from them I need to draw f(x,y) but I only know the definition of f(x,y) as a function of xlocal and ylocal...is there a way to make the transformation...that is to say, is there a way to perform f(x,y) with xlocal and ylocal?See More

Hi Mar,
I saw hyperbolic paraboloid on your page. I've studied those a bit.
