Hi all around,

I just read a paper about growing plants to light and came up with a very silly
idea. The paper is "A Simple but Effective Algorithm to Model the Competition of
Virtual Plants for Light and Space" by William Van Haevre and Philippe Bekaert
(2003). One can find it with google easily. They use an open L-System to model
the plant by calculating special photons to determine the direction the plant
will grow. My idea is to simulate a L-System with the animation feature of POV
(writing the actual string to file, read it in the next iteration, perform the
L-System rules and write it out again). To determine the direction of growth I
will not use this complicated photon issue but simply look through the "eyes" of
the seedlings (branches) using the mesh-cam, distribution type 3, evaluating the
brightesst spot with eval_pigment and use this as the new direction. O.k. this
is a very brief scetch of my idea. My question here is: Has someone of you
implemented a L-System with POV so far. If I have to invent the wheel I will do,
but if someone else did it some time ago, I would like to learn about it. My
searches here yielded no hits unfortunatelly.

Best regards,
Michael
