[comp.graphics] algorithm needed for curve interpolating

mlindholm@cc.helsinki.fi (Mikko Lindholm, Univ. of Helsinki, dpt. of Geography) (03/07/90)

Maybe someone could help me a little.

I'm looking for an algorithm (preferably in C) to draw
(interpolate) a first-order continuity curve through a 
set of given points.  The purpose is to produce isolines.
Any hints, references or listings would be appreciated.

		Thanks in advance,   ml
