OVERVIEW
Aristid Lindenmeyer
Developed the principle to simulate biological growth in 1968
The principle of L-Systems in 3D
is based on the turtle principle. A turtle moves through space with a position vector and three axis vectors
determining its momentary orientation in space (length direction, upwards direction and tilt to the sides).
In the L-Systems there are rules which describe the turtles movement in space in respect to its local
direction vectors (pitch, roll, and turn).
The adaptation of the L-system for MoSS
Modeling of surface and structure uses the L-system primarily with the goal to generate growth
of surfaces. The growth is depending on environmental input. There are attractors and repellers in
the growth environment which influence the angles locally for each new generation.
