This software package bundles all the components, which can be used to process a session of trials collected by a marker based tracking Vicon system. The „old“ Vicon Workstation is supported as well as the current Nexus system.
Read/write routines for file formats specific for the Vicon Workstation are supported (see the table) and the c3d format with the Vicon specific undocumented extentions.
|.enf||Trial/group/session meta data: The files are read from the „Data Explorer“ and during processing of a session/group.||text/vicon-enf|
|.mp||Model parameters (group/session based): These files are used to read/write parameters during processing of a session/group. Its content is shown in the context sensitive properties window if the file is selected.|
|.sp||Parameters (not used)||text/vicon-sp|
|.tvd||Vicon Video Data (recognized but not supported)||application/vicon-tvd|
|.vad||Vicon Analog Data||application/vicon-vad|
|.c3d||C3d file format with Vicon specific undocumented extentions.||application/vicon-c3d|
|.mod||BodyBuilder model files (not yet supported)||application/vicon-mod|
Each Vicon trial is represented by a set of different files, with the same file name, but different suffixes. The marker timeseries are read from the .c3d-files and additional meta data is read from correspoding .enf-files. The enf-Files can include different groups of properties. In the current implementation of the ViconTrialSet class only the properties from the „TRIAL_INFO“ group are read and saved in the .d3d-files in the property group „ALL“.
Additional properties are added to the meta data. Have a look at following table.
|SESSION||This attributes should include the name of a session. The directory name which includes the trial is used as session name if it not starts with „Group“, else the name of the directory which includes this directory is used instead. (This property is added by the ViconTrialSet class)|
The parameters saved in mp-files, can be read and used by the models.
There are some limitations:
Read/write routines for file formats specific for the Vicon Nexus are supported (see the table) and the c3d format with the Vicon specific undocumented extentions as it is used sice Vicon Workstation.
The legacy „.enf“-files from Vicon Workstation are still available in Vicon Nexus. They can externally be modified, by an simple text-editor, or inside Nimue Platform based applications.
