I have a set of x,y, z coordinates and want to plot a smooth line through them rather than just straight lines between and cant seem to find how. Does anybody know if this is possible in Mathematica. Any advice on how I might accheive this using something other than Mathematica would also be appreciated.
To give some detail - there are anywhere between 1000 and 100,000 points and each point also has a rgb value associated with it which is used to colour the line between it and the next point. (see http://nicksoph.wixsite.com/spotline for examples in 2d)
