A Short introduction to using Logo. This is the first in a twelve part series.
Can you use LOGO to create this star pattern made from squares.
Only basic LOGO knowledge needed.
Using LOGO, can you construct elegant procedures that will draw
this family of 'floor coverings'?
Here is a recursive program
TO BRAN6 :T :A
IF 20 > :T [STOP]
FD :T RT :A
BRAN6 :T * (.6 + .02 * RANDOM 10) :A * (.7 + .04 * RANDOM 10) LT :A * 2
BRAN6 :T * (.6 + .02 * RANDOM 10) :A * (.7 + .04 * RANDOM 10) RT :A
This produces a rather satisfying effect when the following is
Why not experiment further by changing the values of variables
:T and :A? Try if possible to anticipate what results before
pressing the return key each time.
Why not experiment with greater/lesser degrees of
Any tentative conclusions?
Can you make smaller trees?
Smaller but stubbier trees?
Tall thin trees?
Tall and stubbier trees?
More geometrically, you might like to consider the following
They build on the patterns that went before, in that they are
obtained from them by introducing a reflection or glide or both.
There are 12 distinct patterns and each can be described according
to an international system of coding.
The first seven are below. As before the invitation is for you
to replicate these patterns (or with a much more flamboyant motif)
using some elegant programming and to study these patterns yet
