That looks pretty impressive to follow within 50 micrometer. I prepared a few versions of the same patters. Each with a different angular interval to generate the curve from 10deg...0.2deg steps. That results in linear segments with lengths from ~0.75mm to ~0.01mm. http://media.vagrearg.org/gcmc/trochoidal-steps.tar.gz I wonder if the smallest angular interval would improve the following and where the breakdown occurs. -- Greetings Bertho (disclaimers are disclaimed) ------------------------------------------------------------------------------ Learn Graph Databases - Download FREE O'Reilly Book "Graph Databases" is the definitive new guide to graph databases and their applications.
