***************************      PERCEPTRON SETTINGS      ***************************


* Perceptron reads this file at startup to set the values of key program parameters.

* The location and name of this file should be Perceptron\resource\Settings.txt.
* We recommend that you do not remove any files from the \resource\ folder in order 
* to secure the operation of Perceptron.

* Comments begin with "*". To specify a variable value, follow the format: 
* variable name + " " + value. 

* Windows denotes paths to files by separating subfolder names with \. Linux uses /
* between the subfolder names. In this file, we used the Windows notation for paths.
* You can use both \ and / for paths in this file, since Perceptron converts them to
* the version that your operating system likes. It is still required that you specify
* paths correctly in a broader sense.


*************************************************************************************


* SCREEN SETTINGS


* The size of Perceptron's canvas in pixels. Perceptron runs in full screen mode in 
* the same resolution for which your desktop is currently configured. However, it 
* utilizes only a small central portion due to speed issues. Possible values are 
* integer numbers greater than 0 and smaller than your current screen resolution.
* Warning. The help screen will not fit the canvas smaller than 580 x 580 in its
* entirety. 
*
* The square canvas allows 1:1 proportion of geometric figures displayed on the
* screen. Other proportions skew the images proportionately. In a video feedback 
* setup, this is believed to be natural behavior. For example, a circle will remain
* a circle on a square canvas. Typical values are from 600 to 1000.


screen_width 960
screen_height 600


*************************************************************************************


* WEBCAM SUPPORT


* If you experience problems when starting Perceptron in Linux, disable the webcam
* support. Options are true, false.

webcam_support false


*************************************************************************************

* WINDOW SETTINGS

* Perceptron was designed to a be a fullscreen application in which the central
* portion of the screen is used as a drawing canvas. However, Perceptron can also
* run in a window whose appearance depends from the operating system that you are
* using. Set windowed_mode to true to use the windowed mode or false to remain in
* fullscreen mode. Press [Enter] during operation to reset the window size and
* position.


windowed_mode false


*************************************************************************************


* FANCINESS


* Fancy graphics are sets of settings that affect objects that are drawn onto screen
* using graphics library. The circle around the selected cursor may appear round and
* smooth. Other effects utilize certain power of graphics hardware. Fanciness might
* slow down calculations significantly, although at present this does not seem to be
* the case. Linux may be faster than Windows. Values from 0 to 4 are available.


fancy_graphics 0


*************************************************************************************


* CONVOLUTION


* Convolution is a crucial process of graphics enhancement, rounding, softening and
* blurring of edges. Value 1 means nearly deactivated, while higher values, up to 16,
* slow down calculations significantly. Applies to convolution modes other than 0.
* (Press y to change convolution mode.)


convolution_degree 1


*************************************************************************************


* PRESETS FOLDER


* Perceptron loads all the presets from the folder Perceptron\resource\presets at 
* startup. The first one on the list according to its name (such as a.state) is the 
* default one. It is necessary to have at least one preset in the presets folder in 
* order to run Perceptron. You can comment out this setting or you must otherwise 
* assure that it is accurate. Perceptron continues to read image(s) denoted in each
* individual preset from the location specified in each preset separately.


preset_folder <resource\presets>


*************************************************************************************


* IMAGE FOLDER


* Perceptron loads all images from the folder Perceptron\resource\images at startup.
* They are available in the image mode or by using certain outside coloring methods.
* The selection of these images that are preloaded at startup depends from the user.
*
* Other images are denoted in presets, Perceptron\resource\presets\*.state files.
* Those particular images should be preserved, so that presets can be used properly.
* You can comment out this setting or you must otherwise assure that it is accurate. 


image_folder <resource\images>


* I recommend that you select the folder carefully and assure that it contains only
* image files. Here is an example of an image folder on a Windows operating system:
* image_folder <D:\My Pictures\test>
* This example shows path to a similar folder in Linux:
* image_folder </home/user/d/My\ Pictures/test/>


* When you later open a saved preset file, the denoted image file must be located on
* your computer at the location specified in the preset file. If you give the preset
* file to another person, you must include the image file if it was used in your 
* artwork. Optimally, store the images that you plan to use in any folder within
* the Perceptron folder. That way, path to image file will be relative to Perceptron 
* and usable on different operating systems.


*************************************************************************************


* EQUATION EDITOR FONT


* Choose a font that is used on screen during the equation editing mode. A list of
* installed fonts depends from each operating system, but some universal font names
* are often used. "Serif", "SansSerif" and "Monospaced" are the most common types.
* Other font ideas could include "Dialog" and "DialogInput". These are all font
* family names that are in some ways, universal.


salvia_font "Serif"


* You may instruct Perceptron to print out the list in a window of all the available
* fonts by name that you have on your system.


print_all_fonts false


*************************************************************************************


* HELP SCREEN TRANSPARENCY


* Help screen is available when you press / during operation (not during the equation
* editing mode). It consists of white text of variable transparency. Value of zero
* gives completely transparent text and thus deactivates help. Fully visible help
* is obtained by setting the value to 255. Values from 1 to 254 produce somewhat
* transparent (opaque) text.


help_font_alpha 255


*************************************************************************************


* TREE SETTINGS


* The fractal properties of the 3D Tree.

* The "depth" or the level of tree branching. Reduce this if the program runs out
* of memory (which may manifest as the program failing to run at all). The number
* of computations required to draw the tree scales as 2^(1 + tree_depth), so the
* time for rendering the tree grows rapidly as a function of depth. Possible values:
* integer numbers from 1 to 29.


max_tree_depth 9


* This is the minimum branching depth. Possible values: integers numbers from 1 to
* 29.


min_tree_depth 3


*************************************************************************************


* EQUATION DEFINITIONS 


* Maps or in other words, functions f(z) that produce Julia fractals. Expressions in
* terms of z. The parameter c will be added (+c) to all equations automatically.
* The red mouse cursor controls the value of c as it moves on the screen.
* For example, f(z) = z^2 + c is equivalent to z_n+1 = z_n^2 + c and we write it as:
* map z*z.

* The recognized constants are:

*   e = 2.71828...
*   i = irrational unit (square root of -1)
*   p = pi = 3.14159265...
*   f = golden ratio = 1.618...
*   w = screen width
*   h = screen height

*************************************************************************************


* SYSTEM-DEPENDENT PREFERENCES STORAGE

* Window preferences such as the last location and size of Perceptron's windows can
* be stored at a location on the local computer according to the standards used by
* the local operating system (Windows, Linux, Mac OS...). Select true if you want
* this type of preferences storage to be used. The advantage is that this storage is
* defined per user and is managed by the local system. The disadvantage is that this
* makes Perceptron leave traces at locations that are not immediately obvious. If you
* move Perceptron to another location, you need to migrate the preferences somehow.
* If you select false, the portable mode will be used. The advantage of portable mode
* is that preferences are stored in perceptron.preferences.user file in Perceptron
* folder and that it can be moved together with Perceptron folder, given to other
* users or modified by hand. Default is false.
* (If you switch the storage, preferences remain in the previous storage and are
* not copied to the new storage.)
