- The L-system interpreter graphtal 1.0 is available
- again via anonymous FTP at iamsun.unibe.ch (130.92.64.10) and
- is found as /Graphics/graphtal-1.0.tar.Z or
- /Graphics/graphtal_no_bison_no_flex-1.0.tar.Z.
-
- ______________________________________________________________
-
- Sorry for the inconvenience, but we had to remove graphtal
- from our FTP server for the following reason:
-
- Jonathan P. Leech (leech@cs.unc.edu) blamed me for not including
- references to his L-system package 'lsys'. There's no excuse for
- my behaviour. Anyhow, I'd like to apologize for misusing Jon
- Leech's effort in that way and I hope that he is satisfied with
- the references added. Please look at the README file for more
- details.

-
- graphtal is an L-system interpreter and is e.g. useful for the
- following tasks:
-
- o generation of geometric objects like trees, plants,
- skyscrapers, ...
- o you can produce different kinds of output including
- output for rayshade, X11 or ppm (portable pixmap).
- o you can use the models produced by graphtal in your own images.
- o you can compute animations with graphtal (refer to the examples).
- o some example L-system descriptions are included (birchtree,
- firtree, a plant, ...) to start with.
-
- Features of graphtal:
-
- o D0L-systems,
- o tables of productions,
- o productions with parameters,
- o stochastically applied productions,
- o global and local constants,
- o hull definitions (turtle interpretation with regard to
- these hulls),
- o production parameters may be strings or real values,
- o animations support,
- o turtle interpreter with macros,
- o preview for X11,
- o Z-buffer preview and output for rayshade.
-
- What you will need:
-
- - C++ compiler
- - bison and flex (if not available get graphtal_no_bison_no_flex.tar.Z)
- - rayshade 4.0.6 and the URT toolkit (necessary for the rayshade driver)
-
- Supported platforms:
-
- - Sun SparcStations with Sun C++ 2.1, Sun C++ 3.0, AT&T 2.0, AT&T 3.0
- and g++ 2.2.2
- - IBM RS/6000 with AT&T C++ 2.0
- - DEC Station with DEC C++ 1.0 or g++
-
- Examples:
-
- In the directory graphtal/Examples some interesting L-systems are
- included. The animation scripts will need nawk or gawk in order
- to work.
-
- Please send bugs (accompanied by L-systems causing them),
- interesting L-systems for inclusion in the release, enhancements,
- and suggestions to the author via email.
