Line 4:
Does anyone know where the values in the fern IFS come from? For example, the map to draw the stalk is rather counterintuitive, because it seems to draw along the y-axis, whereas the actual stalk itself is made up of several segments increasing in their x-values. How would you go about deriving the values in the IFS (0.16 etc) if you didn't already know them, and what relations exist between them (e.g. if you changed one, how would you need to change the others to keep the fern "together")? I know Barnsley's Collage Theorem may be involved, but I'm not sure to what extent. [[User:Kidburla2002|Kidburla2002]] 00:04, 11 May 2007 (UTC)
I agreee, that's why i propose replacing it with the much simpler spiral at the bottom of this page. This IFS has simpler equations and fewer transforms, and the illustration includes several steps. The fern example is good for showing how complex natural shapes can be reduced to IFS, not for understanding IFS. [[User:Spot|Spot]] 19:24, 18 August 2007 (UTC)
