Changes and additions in Lparser v2.0 :
────────────────────────────────────────────────────────────────────────────
The lparser now generates POV 2 syntax format. The l_base shape can be a
single sphere since they can now be unequaly scaled. See exam.pov. This gives
much more accurate shape control then before. Because of the auto-bounding,
very large shapes done with the -v option can be traced quite fast.
All POV examples scenes are now in POV 2 syntax format. Setup files for the
different POV setups using include files.
A fast wire-frame viewer has been added which can be used to explore the
form in 3d and do quick hidden polygon images. It can now also read 3DS
files, does better FractInt RAY file processing, uses SVGA, multiple windows
with location and orientation feedback and better key usage.
LV2POV to allow you to use the viewer with FractInt and POV for the
easier generation of traced fractal landscapes.
The lparser can output RAW files directly.
Degenerate triangles are filterd out by the lparser.
More flexibel use of comments in .ls files.
Some syntax additions too allow for more 'tree' like shapes. The files
tree*.ls are based on the tree models described in "The Algorithmic Beauty of
Plants" in chapter 2. The extras includes :
Extra commands like :
$ roll until horizontal (as described on page 57).
~ turn/pitch/roll in a random direction (which can
be used for random direction leave placement).
t gravity correction based on the tropism mechanism (as on
page 61). The tropism vector is straight down.
Parameterised commands in the form +(number) too allow more fine
tunning.
