README.AMIGA (2nd Version 12.93)
=============
- To compile Graphtal on the Amiga you need GCC-233, the os-includes
and a lot of memory. (compilation without optimizer: about 6MB)
Don't forget to set a large stack size (256000 is fine) !
Because AmigaDOS isn't case sensitive you must edit string.h
(for more information on this read the header of string.h)
(NEW) Do also read the file IMPORTANT.README.AMIGA
- Graphtal has a device for Rayshade output.
- I have include some tools to convert PPM output to IFF24 in bin
(to convert PPM output to IFF get the the PBM plus package)
- Note: some examples for Graphtal need a lot of memory (over 10MB) !
- Note: Graphtal needs the cpp to process the inputfile.
(NEW) cpp and sh are now included in the directory Unix
- GCC-233 and Rayshade are available by anonymous FTP in ftp.luth.se
or any other Aminet site
- (NEW) Note: setting the environment variable COLORFILE now works
(see changes in file color.C)
- (NEW) examples how to use graphtal can be found in the file EXAMPLE.SCRIPT

DESCRIPTION
graphtal is a tool for manipulating spT0L-systems (context
free, table oriented L-systems with stochastic productions).
graphtal reads a file containing an L-system description and
starts the interpretation. In addition, graphtal is able to
interpret the result graphically, producing different kinds
of output.
The main reference for the program is the book The Virtual
Laboratory: The Algorithmic Beauty of Plants by P. Prusink-
iewicz and A. Lindenmayer. The language used in graphtal is
different from the one in the book and will be described
completely in this document.
DEVICE DRIVERS
EXAMPLE DEVICE
The example driver produces a ASCII dump of the primitives
generated. It shows the easiest way to implement a driver.
BBOX DEVICE
The bbox driver computes the bounding box and gives a hint
for the viewing parameters of the objects defined by the L-
system description. This is useful for the flat device,
which does no automatic view computations.
LINE DEVICE (X11,AMIGA)
This driver generates a simple line drawing of the object
defined by the L-system. Line width, color, textures,
spheres, macros and library object are not supported by this
driver. Viewing parameters are automatically set, when none
are provided by the user.
WIRE DEVICE (X11,AMIGA)
The wire device driver draws a more realistic image of the
object than line device. Not supported are colors, textures
and library objects. Viewing parameters are also set
automatically, when none are provided.
FLAT DEVICE
The flat device works with a z-buffer algorithm, which is
able to shade convex and concave polygons. Shading calcula-
tions are done with regard to the light source located at
the eyepoint. The driver does not depend on the number of
polygons, therefore even very large scenes can be visual-
ized. As a drawback of this feature, the viewing parameters
have to be provided by the user (use BBOX DEVICE to calcu-
late them). Textures and library objects are not supported
by this driver. The output of the rendering process is an
image in ppm format (portable pixmap).
RAYSHADE DEVICE
The rayshade device is the most complete of all the drivers.
It generates output for the raytracer rayshade. The driver
produces at least two output files:
graphtal -d rayshade anExample.lsys
generates the files default.ray and default.ray.def
graphtal -d rayshade -O anExample.ray
generates the files anExample.ray and anExample.ray.def.
The file name.ray contains the options for the rendering
process and in the name.ray.def file the geometric primi-
tives are stored. For each macro definition, the rayshade
driver produces it's own file with the name
macrName.ray.def. If library objects are used, a file with
the name libraryName.ray.lib must be provided by the user
for each object.
