Changes and additions in v2.1 :
────────────────────────────────────────────────────────────────────────────
Speedup of the lparser. Forms which used to take up to an half hour to
generate are now parsed in couple of seconds ! This makes much larger and
complexer l-systems posible and workable (see the gif images on disc). Much
higher recursions levels are now also attainable.
The -i option is removed since the time to parse a complex form is very
much shorter now. Maximum production string length is now about 1.5 million
chars.
Count downs on expanding and parsing to track the status of the parser. The
number after expanding counts down from the number of recursions to 1, the
number after parsing is the percentage yet to process. On completion you
will get the total production string size in chars and the total number of
objects written to the output files.
Echoing the input l-system and extra information to the screen is now an
option (-e). Using the -e option will give screen feedback as was outputed
in v2.0.
Lviewer exits when no polygons are found to display.
Lv2povid can now convert all output files into ready-to-trace POV (1 or 2) and
Vivid/BOB scenes, using the a viewport selected in the lviewer. See lv2povid.doc.
Values can have some randomness automaticly added to them. Using ~(xx) will
now add a random direction component to the current orientation with maximum
of xx in all three directions. This way you can mark at which locations in
your l-system 'jitter' needs to be introduced. Using this option no two
'intances' of the same l-system will look the same. See fern.ls for an
example.
With the (new) -i option you can generate a connected set of base forms based
on a 8 sided cylinder element. It will connect the bottom part of the
cylinder to a previous top part.
If the string gets to large to fit in the reserved production string area
you will get the message "incomplete".
The -s [num] option to set the maximum size of the production string for
better memory sizing.
