Compiling the Code

Iterated Dynamics uses a CMake based build. You will need CMake 2.8.11 or later to compile Iterated Dynamics. Use CMake to create a build for your preferred development environment.

These instructions assume a build directory called build at the top level of the source tree. Run CMake from the build directory to create the build script:

OS Command
Linux cmake -G "Unix Makefiles" ..
MacOS with make cmake -G "Unix Makefiles" ..
MacOS with Xcode cmake -G Xcode ..
Windows cmake -G "Visual Studio 12" ..

Once the appropriate build script is generated, then build the code normally.

The build will first compile hc, the help compiler. This generates the run-time help file from the help source files and an include file used by the iterated dynamics compile.


Iterated Dynamics welcomes contributions from everyone! The code has a long history of contributions from many people over the years. There are many small ways in which the code can be improved as well as large changes that are on the release plan.

To get started, fork the repository into your github account. We recommend using the github workflow to make contributions to Iterated Dynamics. We recommend you enable Travis CI builds on your repository to get feedback from static analysis tools on your changes as you push to your branch in your repository.

Once your change is ready, prepare a pull request and submit it back for incorporation into the main repository. We couldn't have gotten this far without contributions from many persons!

Code Structure

  • common Files common to all implementations

  • 3d Files containing 3D drawing support. Eventually these should be subsumed into the driver interface, with this sofwtare implementation as a fallback if the driver doesn't support 3D rendering.

  • engine Files containing the implementation of the fractal rendering engines that are shared between multiple fractal types. Also contains the big array that defines the available fractal types.

  • fractal specific Files containing rendering code or user interaction code that is specific to a particular fractal, such as the Lorenz fractal or L-system type.

  • i/o Anything related to doing external file I/O: saving and loading GIF files, dealing with overlay files, saving parameter files, etc.

  • math Files containing math routines for arbitrary precision arithmetic, complex arithmetic, etc.

  • plumbing Miscellaneous routines that don't fit elesewhere like memory and driver management.

  • ui Anything to do with displaying menu screens, help screens, intro screen, etc.

  • main Miscellaneous files in the main fractint source folder. These are not currently used for any of the compilation of the code and are placed here just for reference.

  • headers Header files

  • hc Help source files with a custom build step on help.src to run the help compiler on the source to generate new fractint.hlp and helpdefs.h files.

  • unix Files needed for the unix platform.

  • win32 Files needed for the Win32 platform.

You can’t perform that action at this time.
