---------------------- README.TXT for TREES.ZIP -----------------------------

TREES.ZIP contains files for rendering realistic ficus-like trees in
POV-Ray 2.0. The tree object (MYTREE.INC) was created with Lj Lapre's
L-System Parser/Mutator, available on CompuServe's GRAPHDEV forum.
L-Systems are "an algorithmic approach to the description, analysis, and
developmental simulation of multicellular organisms" originated by Aristid
Lindenmayer, a theoretical biologist. For more information, see
Lindenmeyer and Prusinkiewicz' article in "Artificial Life," edited by
Christopher G. Langton (Addison Wesley, 1989); or see "The Algorithmic
Beauty of Plants," by Prusinkiewicz and Lindenmeyer.
In addition to this README file, TREES.ZIP contains:
TREES.POV example scene and textures
MYTREE.INC the MyTree object
BARKTEX.GIF bark texture bump_map
MYTREE01.LS a script for generating a lush, small-leaved tree
MYTREE03.LS a script for the tree in MYTREE.INC
Note: if you generate your own *.inc files with L-Parser, you may need to
enter texture references by string search-and-replace. The L-Parser output
creates pigment{} and finish{} statements for each sub-object, rather
than texture{}. MYTREE.INC has been hand modified for the textures in
TREES.POV.
Thanks to Lj Lapre for LPARSER and for TREE05.LS on which MYTREE*.LS is
based.
