C3D-to-AnyScript converter

Most motion capture system store data i the C3D file format. To facilitate the use of such data for modeling in AnyBody a converter is now available for download from our website.

c3d2any is a new console application that allows you to convert a C3D file into AnyScript files which can be used for creating biomechnical models in the AnyBody Modeling System. c3d2any is compatible with AnyScript version 2.0 and 3.0.

Each C3D file processed results in eight output files. One is an AnyScript main file. Running this will display the motion of the markers. Five of the eight files contain information that are specific for the c3d file that was processed:

• Header.any which contains the header information
• Group.any which contains the group information
• PointsMarkers.any which contains all the 3D data points that have been measured 
• PointsProcessed.any which  contains all processed 3D data points
  Note: This distinction is made based on the content of the camera mask byte for each 3D point. 
• Analog.any file which contains the analog measurement section (e.g. EMG)

Additionally, MarkerListMover.any and MarkerMover.any define a segment and create kinematical drivers for each 3D point in the PointsMarkers.any file so that the segment follows the measured data.

AnyBody seminar in Dresden, Germany, Nov. 21

Tips and tricks #10: Interpolation drivers

A example showing graphically the use of a driver function that interpolates between data points spaced in time has become available in the AnyScript Yahoo Group (in the SmallExamples folder). The example visualizes the following types of interpolation as curves: Piecewise linear function, Bezier interpolation, and B-Spline interpolation of variable order.

Meet an AnyBuddy:
Michael Damsgaard

Michael, 37, is Head of R&D, key developer and software architect in AnyBody Technology.

He holds a MSc and a PhD in mechanical engineering from Aalborg University, Denmark, where he became an Associate Research Professor prior to joining AnyBody. Michael’s primary academic interest and his former research topic is multibody dynamics.

In 1997 Michael wrote the first piece of code for what later became the AnyBody Modeling System (together with John Rasmussen). He is a co-founder of AnyBody Technology and a member of the Board of Directors.

Michael lives with his wife and two children in a village 2km from the office in Aalborg. Located next to a forest in rural sorroundings their home often serves as base camp for hiking and running expeditions. Their passion for  wilderness, mountains, and other challenges often brings them outside Denmark, for instance for skiing in the winter time. Michael plays in the local soccer club, even though he says that it is difficult to satisfy his ambitions in a team sport when being used to solo sports like running, biking, and karate. “In particular when ambitions are not matched by time and skills”, he reluctantly adds. 

The above picture shows Michael ready for the Saturday morning Breakfast (fun) Run at Berlin Marathon this September.
