- Introduction
- ~~~~~~~~~~~~
- Tessels is a program for generating random backdrops or textures.
- It draws some lines, applies a diffusion algorithm and a blurring.
- This happens for a number of times or "passes". Then a random
- palette is generated, and an IFF ILBM file is saved. It's important
- to note that the generated file is saved in _UNCOMPRESSED_ format.
- Load it and save it again with an image utility if you want it
- compressed.
-
-
- Usage
- ~~~~~
- The command line template for Tessels is this one:
-
- FILE/A,SEED/N,WIDTH/K/N,HEIGHT/K/N,LINES/S,ANGLES/S,PASSES/K/N,
- DIFF=DIFFUSION/K/N,LW/K/N,LVW/K/N,LN/K/N,LVN/K/N,LV/K/N,
- AW/K/N,AVW/K/N,AN/K/N,AVN/K/N,AV/K/N,AA/K/N,AVA/K/N,ALE/K/N,
- AVLE/K/N,PLANES/K/N
-
- FILE: The filename for the output file.
-
- SEED: A seed for random number generation; the same seed with the
- same parameters gives you the same picture.
-
- WIDTH: The width of the output image.
-
- HEIGHT: The height of the output image.
-
- PLANES: The depth of the output image (upto 8).
-
- LINES: Activates lines. Start and end points of lines are selected
- randomly in the picture.
-
- ANGLES: Activates angles. Start points of lines are selected
- randomly, angle and length are selected around some specified
- values (this gives wave-like textures).
-
- (If none of LINES or ANGLES keywords are specified, LINES is
- automatically selected. Both may be used at the same time.)
-
- DIFF=DIFFUSION: This is the maximum distance in pixels for pixel
- displacement during diffusion phase.
-
- (The following parameters take suitable "default" -random- values
- if not specified)
-
- LW: Average line width for "LINES".
-
- LVW: Maximum variation for line width for "LINES".
-
- LN: Average line number for "LINES" in each pass.
-
- LVN: Maximum variation for line number for "LINES" in each pass.
-
- LV: Maximum dot position variation for "LINES".
-
- AW: Average line width for "ANGLES".
-
- AVW: Maximum variation for line width for "ANGLES".
-
- AN: Average line number for "ANGLES" in each pass.
-
- AVN: Maximum variation for line number for "ANGLES" in each pass.
-
- AV: Maximum dot position variation for "ANGLES".
-
- AA: Average line angle for "ANGLES".
-
- AVA: Maximum variation for line angle for "ANGLES".
-
- ALE: Average line length for "ANGLES".
-
- AVLE: Maximum variation for line length for "ANGLES".
-
-
- Several compiled versions are included:
-
- -68000 version.
-
- -68020 version.
-
- -68030+68881 version.
-
- -68040+68881 version.
-
- For the best speed use the one that best matches your
- configuration.
-
-
- Be happy with Tessels!!! (I have it changing randomly my backdrops
- each boot and I'm happy :-)
