Augmented reality pattern marker generator

This online tool creates the Augmented Reality (AR) pattern marker files (.pat) used by the ARToolkit, NyARToolKit and FLARToolkit. Print out a single marker or multiple markers on a single sheet of paper and hold it in front of your webcam. This tool will genenerate a single pattern file (.pat) or a zip file containing multiple pattern files.

The pattern files are just plain text files loaded by the above mentioned toolkits so that it knows what markers to track in the video stream.
