System information

Glossary-30 Vicon MX Hardware System Reference
3D Workspace. Also see 3D Workspace,
Global coordinate system, and System
calibration.
Workstation Vicon application software
for data acquisition and processing of
optical motion capture. It contains
functionality to set up, calibrate, acquire,
verify, edit, and process motion data from
Vicon systems as well as analog data
from third-party devices such as EMG and
force plates. It also controls capture of
digital reference video and real-time data
streaming.
Workstation is the core motion capture
and processing software for life sciences
applications. A range of plug-in software
is available to extend Workstation
functionality. Also see Plug-in, PECS,
Plug-in Modeler, and SIMM export plug-
in.
X
.x1d file A binary file with extension
.x1d, which contains unprocessed data
from analog data capture in Vicon Nexus.
By default, .x1d files are saved to the
active Session folder of the open
database. Similar functionality is provided
by the .vad file in earlier Vicon application
software. Also see Nexus and .vad file.
.x2d file An XML file with extension
.x2d, which contains 2D camera data
previously captured in Vicon MX systems.
This can be a mixture of unprocessed
grayscale blobs, calculated centroids, and
coordinates data. By default, .x2d files
are saved to the active Session folder of
the open database. Also see Centroid,
Coordinates data, Grayscale blob, and
Vicon MX.
.xcp file An XML file with extension
.xcp, which contains the calibration
parameters and threshold data specified
for Vicon cameras and supported third-
party digital video cameras in Vicon
Nexus. This file is created during the
MX camera and DV camera calibration
processes and used when data from
these cameras is processed. A copy of the
.xcp file is saved to the active Session
folder of the open database. Similar
functionality is provided by the .cp and
.vtt files in earlier Vicon application
software. Also see .cp file, DCAM, DV,
Nexus, and .vtt file.
.xml file eXtensible Markup Language
file. A condensed form of SGML (Standard
Generalized Markup Language) which
defines a language standard used to
create customized tags for organizing and
presenting types of information in
documents that can be published on the
World Wide Web. A number of Vicon file
types are in XML format. Also see .vsk
file, .vst file, and .vtt file.
Z
Zoom lens A camera lens with a
variable focal length and whose angle of
view can be changed without moving the
camera. See MCam2, MX13/MX13+, and
MX40/MX40+.
Zoom ratio The ratio of the longest and
shortest focal length of a zoom lens. Also
see Focal length and Zoom lens.
