INTRODUCTION
============
This program is the first working version of a sofware developed to
obtain better result for SIS (Single Image Stereogram) by generating
pattern files to 'cover' the holusions.
I was tired to always see the same RDSs (Random Dots Stereograms)
made of simple random pixels, so I wanted to innovate stereograms
by writing this program... I hope someone likes this!
The output of this program is a simple .TGA file (truecolor 24 bit,
compressed or uncompressed) which contains the pattern to use with
the SIS generator; obviously you need a SIS generator (like CRUMBLER)
to see the final result on your stereograms.
PMAKER 1.0 is able to generate 15 different kind of image patterns,
by implementing geometrical, fractal and trigonometrical functions and
uses a random color generation to obtain always different results.
For each feature you have a lot of options to improve your works,
see next chapters about.
- HOW TO USE - - 1 -
1.0 HOW TO USE PMAKER -intro-
=========================
PMAKER is totally batch oriented. Every option that you require
to use must be inserted into the dos prompt command line.
I'm not too sure if alot of people like this layout (may forget an
option, must remember the right syntax, etc.), anyway I choose this
layout because you can run PMAKER inside a batch file and that I can
also avoid writing tedious user interface that could not be nice but
needs alot of time.
Anyway, the next version of CRUMBLER will include PMAKER with a GUI.
The syntax is not too hard to remember, I tried to associate a
menmonical name for each option.
1.1 BASIC SYNTAX
============
First, say PMAKER doesn't require an input file.
Type at your prompt dos:
> PMAKER <filename[.TGA]> <basePattern> [+<options>]
- <filename> is the output .TGA file (".TGA" can be omitted)
- <basePattern> is one of the 15 following features:
stain, blur, line, wave, tube, ripple, circle, spot, sphere,
bubble,square, mine, lake, star, sky
(see 2.x about features)
- <options> are *A LOT*! There are:
- general options (these are valid for each feature)
- specific options (for each feature there are specific options
which design the characteristics of the pattern)
All the supported options are omittable and for each option
there's a Default value to make PMAKER easier.
To see help about specific options see 2.2.x
- HOW TO USE - - 1 -
1.2 GENERAL OPTIONS
===============
General options tell PMAKER which range of colors to use and give
the information about the output file:
+xXXX horizontal resoulution (each value is right, limit is your
conventional memory)
+yXXX vertical resolution (no limits)
+o tells PMAKER to overwrite an existing file;
if omitted PMAKER stops if encounters an existing file.
+rle lets PMAKER create a compressed Run LEngth .TGA file;
if omitted the output is uncompressed.
+scRRR,GGG,BBB -and-
+ecRRR,GGG,BBB tell PMAKER the starting and ending colors for random
color generation: PMAKER uses red values between
scRRR and ecRRR, green between scGGG and ecGGG, etc.
+tcRRR,GGG,BBB is the Top background color
+bcRRR,GGG,BBB is the Bottom background color
These are used only when choosen feature requires them.
Each RRR, GGG, BBB are 0..255 value, so this is an example:
> PMAKER out.tga sky +sc0,0,0 +ec255,255,255
(+[s|e|t|b]cRRR,GGG,BBB options needs NO spaces between r,g,b colors!!)
1.3 HOW TO GET HELP
===============
If you want to see PMAKER's basic help type:
> PMAKER ?
(this will show the general options above) and type:
> PMAKER ? <basePattern>
to obtain help on specific options about <basePattern>.
- BASIC CONCEPTS - - 2 -
2.0 BASIC CONCEPTS -intro-
======================
PMAKER is made of simple routines which make use of pseudo-fractals
random color distribution, or mathematical simulation of interference
between different 2D waves or random colored shapes generation.
These routines have been simple to implement and lot of the
patterns results are 'cylindrical', such as the right-hand side can
be placed next to the left-hand side without appearing discontinuous.
This is useful for SIS, in which the patterns are always placed next
to each other.
Unfortunately this feature causes a little loose in execution time.
The base patterns are made of simple shapes like circles (empty,
filled or blur), lines, 'waved lines', stars and squares or
random color distributions (similar to plasma) or pseudo-fractal
actractors which causes odd color patterns.
2.1 FEATURES
========
There are 15 available features (as shown), but few are very similar
in facts they differ only on the filling method.
These are the base patterns available:
- stain (pseudo-fractal actractors, COOL!)
- blur (similar to plasma, VERY NICE!)
- line (disorded and different thickness lines)
- wave (disorded monodimensional blur waves, THE BEST!!)
- tube (similar to wave but with a 'depth' appearance)
- ripple (a single random-colored linear ripple)
- circle (empty circles)
- spot (filled circles)
- sphere (depth effect circles)
- bubble (blur circles)
- square (regular flat subdivision in squares)
- mine (similar to 'mine-sweeper' background)
- lake (interference between 2D waves, NOT NICE FOR SIS BUT GREAT!)
- star (four tips stars)
- sky (random dots)
- SPECIFIC OPTIONS - - 2 -
2.2 SIMPLE HELP FOR EACH FEATURE
============================
The following helps are a simple description about the options you
can use for each base pattern. Often the same options are valid for
more than one base pattern, maybe only a slight difference
in their meanings. So check the help that is avaible or use the
PMAKER ? <pattern>
command line to see the help commands.
2.2.0 STAIN
=====
This is the pseudo-fractal random actractor pattern generator.
Specific options are:
+nXXX number of random placed actractors
+lXXX onion level. The rgb color values are multiplied for +l option
and divided for 256; the remainder is used as color.
It gives a nice 'onion' appearance to the image.
Good values are 5..20
+rMIN,MAX tells the random number generator the range of the possible
values of the actractive ray for each actractor.
Good values are 80-120; Max should be < +x option.
This topic doesn't care about the background colors (see 1.2)
2.2.1 BLUR
====
This is similar to 'plasma' fractal, but it's calculated in a easier
way: for each <+d> pixels the function calculates a random color, then
it fills empty pixels by averaging the closed calculated pixels.
Specific options are:
+dXXX distance between a random color and the next one
Good values are between 1 (totally random dot) and 10.
Higher values can make SIS loose details.
This topic doesn't care about background colors (1.2)
- SPECIFIC OPTIONS - - 2 -
2.2.2 LINE
====
Creates disorded lines with different thickness.
+nXXX number of lines to be draw
+wMIN,MAX thickness range value
This topic uses every generic options.
2.2.3 WAVE
====
Similar to line topic, draws monodimensional disorded waves.
+nXXX number of waves
+wMIN,MAX range for thickness values
+fMIN,MAX range for frequency values, floating point
+aMIN,MAX range for amplitude values
+pMIN,MAX range for phase values, floating point
Uses every generic options.
2.2.4 TUBE
====
This topic is VERY similar to the previous, but the wave borders
fade to background color.
+nXXX number of tubes
+wMIN,MAX range for thickness values
+fMIN,MAX range for frequency values, floating point
+aMIN,MAX range for amplitude values
+pMIN,MAX range for phase values, floating point
Uses every generic options.
- SPECIFIC OPTIONS - - 2 -
2.2.5 RIPPLE
======
It's a simple linear wave randomly colored.
+wMIN,MAX range for distance values between one random color and next
+fMIN,MAX range for frequency values, floating point
+aMIN,MAX range for amplitude values
+pMIN,MAX range for phase values, floating point
Doesn't care about background colors (1.2).
2.2.6 CIRCLE
======
Draws empty circles
+nXXX number of circles
+rMIN,MAX range of rays values
Uses every generic options.
2.2.7 SPOT
====
Very similar to 'circle' topic: these are filled!
+nXXX number of spots
+rMIN,MAX range of rays values
Uses every generic options.
- SPECIFIC OPTIONS - - 2 -
2.2.8 SPHERE
======
Similar to previous topic, fade the spots to background giving a
spherical appearance.
+nXXX number of spheres
+rMIN,MAX range of rays values
Uses every generic options.
2.2.9 BUBBLE
======
Similar to previous topic, fade the spots to background after
previous generation, giving a 'trasparency' effect.
+nXXX number of bubbles
+rMIN,MAX range of rays values
Uses every generic options.
2.2.10 SQUARE
======
Fills the image with regular randomly colored square.
+dXXX side of the squares. It's better if +x option (1.2) is a
multiple of 'side', otherwise the last column on the right
is NOT made of squares. Good values are between 1 (RDS) and 5.
Doesn't care about background colors (1.2);
- SPECIFIC OPTIONS - - 2 -
2.2.11 MINE
====
Similar to square, but embossed. 'Mine' comes from MineSweeper for
windows: the final result is similar to a multicolored keyboard.
+dXXX side of base square (2.2.10). Must be > 1.
+hxxx height (prominence) in pixels. Must be < +d and > 0.
Good values are +d6 +h2 or a little greater.
This topics doesn't care about background colors (1.2).
2.2.12 LAKE
====
Lake a particular base pattern. Draws interference between
bidimensional waves. It's not good as pattern for SIS (and it's VERY
slow too), but you can use it to generate big images, don't know,
to use as windows background... It's not bad!
+nXXX number of waves
+lXXX onion level (2.0). Best value is 1, higher values changes
colors... Experiment!
+rMIN,MAX range for ray of influence values (experiment!)
+fMIN,MAX range for frequency values, floating point.
Good values: 0.5 - 10.0
Doesn't care about background colors.
2.2.13 STAR
====
Fill the background with stars. The stars tips fade to background.
Best results for black background and bright stars.
+nXXX number of stars (good values: 100..2000)
+wMIN,MAX range of lenghts for stars tips (good values: 5-10)
Uses every generic options.
- SPECIFIC OPTIONS - - 2 -
2.2.14 SKY
===
Simply fills the background with random pixels.
Gives quite good results for SIS. Pretty cool!
+nXXX number of active pixels (don't exager... it's quite slow!)
Obviously uses every generic options.
