Corrected birch trunk and added one more trunk -
trunk#5 = trunk#2 + trunk#3
The image was slightly distorted using 'normal' in camera.
I would apriciate your help if you know how to add spline
path to these trunks and how to make it conical.

To make it conical, use instead of

x*x + z*z - 1

somethink like

x*x + z*z - (1-y/30) [to fit into your container].

To make it follow a spline you should declare the spline as a function and
the isosurface function

#declare Spline_Fun= function{ spline{...}}
#declare Iso_Fun=function{}

In the isosurface use somethink like

function{Iso_Fun{x+Spline_Fun(y).x,y,z+Spline_Fun(y).z}}.

A good reference for such methods is the Isosurface tutorial
http://www.econym.demon.co.uk/isotut/index.htm. The described method is also
used in the "New Tricks" section.

Hope that helps!

Good work btw!
