1. Getting Started

   A. About JWF
       i. Introduction
            a). Flame fractals examples and definition.
       ii. JWF history
            a). Scott Draves
            b). Apophysis
            c). JWildfire
       iii. JWF online
            a). jwildfire.org
   B. Launching JWF

Please use always the official launcher to start JWildfire. The launcher can be

executed by any Java runtime and can be started with any options.

The task of the launcher is to launch the main software with controlled options

and to reserve enough memory.

- under Windows use the start_windows.bat to start the launcher.

- under Mac OS use the start_mac.command to start the launcher.

- under Linux use the start_linux.sh to start the launcher.

If this doesnt work or if you have another operating system not listed here

just start/open the j-wildfire-launcher.jar directly.

PLEASE DO NOT START THE j-wildfire.jar DIRECTLY!

If you start the j-wildfire.jar directly then JWildfire is started with default

Java otions.

In the most cases you cannot render large images with those settings because not

enough memory is reserved at startup. So even if you have plenty of memory it can

not be used for rendering this way. Additionally, the wrong settings may cause

slower rendering.

HOW THE LAUNCHER WORKS


It analyzes certain system settings to locate java runtimes on your system and

automatically selects the most recent one. You can override the automatically

selected version by selecting another entry in the listbox.

If the scanner did not find a java runtime (probably on Macs as I have no way to

test this) you can manually add it. You must do this only once, of course.

The memory setting lets you specify the maximum amount of memory in megabytes to use.

This memory amount is only allocated if required. But there is no way to allocate

more memory than here specified if JWildfire is already running.

I. e., you must choose this value wisely.

Example: 6000 MB should work fine to render images in high-end quality for print.

TROUBLESHOOTING


The launcher works in two ways: regular and debug mode. In regular mode it just

start JWildfire and shuts down itself.

If you face any problems (i. E., JWildfire does not start) please activate the

"Debug" checkbox. This forces a traced launching where log messages are recorded

and displayed at the "Log messages" tab.

You can easily copy those messages into the clipboard by using the "To clipboard"

button and then report them for further assistence.



   C. Basics
       i. The Interface
       ii. Creating fractals
       iii. Rendering fractals
              a. what is rendering and why do I have to do it?
              b. the various renderers.
              c. when should I use the interactive renderer?
       iv. saving files in JWf
              a. saving files from the flame editor
              b. saving files from the interactive editor
              c. resonance hdr files
       v. Known problems and solutions
              a. Mac OS X issue:(included in a private message from Andreas Tuscher)
                    "Hello, 
                     I had quite issues to run JWF for the first time on Mac OS X. 
                     It took me a while to understand that JRE was not enough for running it 
                     but I figured out finally that I needed to instal JDK 
                     and select the JDK path rather the JRE path for JWF to run.   "
              b. Windows issue: windows error message "could not locate Javaw..."  
                     This issue happens either because one does not have java installed or there
                     is a problem with the last installation of an update.... the solution is
                     to remove any versions of Java on one's computer and to download the latest version.
