L-System 4, by Timothy C. Perz, generates 3D models in DXF format for importing into 3D programs such as Bryce, Truespace, Ray Dream or any program which recognizes the DXF file format. Bitmap and Jpeg file export features are included, allowing you to use L-System models in 2D paint/photo programs. Even if you know little or nothing about 2D/3D graphics, L-System 4 is still a fun and easy program to use. All you do is install the program, load an LS File, click on the Generate button and in seconds you will be enjoying your very own creations!
The program comes complete with install/uninstall instructions as well as an extensive ReadMe file, program Help File, and model presets. It works in Windows 95/98/NT/Me/2000, and may work with Windows XP, although that hasn't been tested.
L-System 5 (beta), by Timothy C. Perz
Tim's hard at work on L-System 5. Among the improvements in this first beta release are:
- Fixed the DXF output so that you can access the individual layers in other programs (i.e., Bryce, Truespace, Ray Dream, 3DStudio)
- Added building blocks for Cones, Pyramids, and Cubes
- Modified the basic cylinder to have 16 sides instead of 8, giving a smoother looking output
You'll need L-System 4 installed to use this. Just unzip the files into your existing LSystem4 directory, create a shortcut to Lsystem5.exe, and you're ready to go. Nothing in the old program is overwritten, so you can try this beta without having to uninstall anything should you want to go back to using version 4.
I'll be posting new versions as they become available, so check back for updates or subscribe to the email notification list below. Your info will not be shared with anyone for any reason.
