PEN 2.0 alpha

Penrose-tiling editor software

Description

PEN 2.0 alpha - Penrose-tiling editor. Editing Penrose-tiling is unsolvable problem by mechanic tools, because of the five-fold symmetry. The software is a result of long development and it was made for tool, not for end-user program. I used at many artworks, but its main purpose was making the 100 Drawings series.

Features:

• Editing by shape to shape
• Automatic tiling generation
• Colorable shapes
• Zoom functions
• Printing
• Shapes can be replaced by drawings
• Special drawing tools for drawings, which replaces the shapes.

Future features:

• Postscript file export
• Bitmap file export
• Extending the drawing tools
• Help and documentation

The present version is stable, and most of the functions work well. The drawing tools are rather chunky, and printing opties too.

System requirements:

The software runs on IBM compatibles under Windows 9x. You need a mouse, and a connected printer for printing.

Special thanks

The software could not be realized without Sir Roger Penrose, id he does not invent the Penrose-tiling.

Also could not be without the help of Dik Groot, dutch mathematician.

Basic development was on Silicon Graphics System of Atelier Brouillard-Precis. At the and, but not last, Eric Weeks, American crystallographer, whose algorhytm is used for automatic tiling generation.
