Usage

----------------------------------------------------------------------
|

|
||||
USE: lindenmayer setup-window
|
||||
|
||||
Towards the end of the "lindenmayer.factor" file, there are words for
|
||||
various L-systems. Let's pick abop-1, which is an example from the
|
||||
book The Algorithmic Beauty of Plants
|
||||
|
||||
abop-1
|
||||
|
||||
Look at the axiom
|
||||
|
||||
axiom get .
|
||||
|
||||
And the productions
|
||||
|
||||
rules get .
|
||||
|
||||
The string to be interpreted is stored in the result variable. Start
|
||||
off by calling init to copy the axiom to result
|
||||
|
||||
init
|
||||
|
||||
Look at result
|
||||
|
||||
result get .
|
||||
|
||||
It's just the axiom. Now iterate the string
|
||||
|
||||
iterate
|
||||
|
||||
You should see a branch and a leaf. Look at the result again:
|
||||
|
||||
result get .
|
||||
|
||||
Call iterate as many times as you want. :-) After about 4 iterations
|
||||
the tree starts to grow beyond the edge of the window. Change the
|
||||
point that the camera is looking at:
|
||||
|
||||
{ 0 0 3 } camera-focus set-global display
|
||||
|
||||
You can also change where the camera is located:
|
||||
|
||||
{ 0 0 10 } camera-position set-global display
|
||||
|
||||
Happy gardening
