Blade Introduction
Currently at the Studio in
SCAD-SAV, we are using a passive optical system with 12 Vicon MX
series cameras: MX4 (4 mega pixel) with Vicon Blade 3.3.1 (new
Spring Quarter). Our volume has increased roughly 3x the
original size from 2010 due to the improvements in software
(2.6) installed Dec 2013 (by about one foot all around) since it
has less difficulty with occluded markers as well as the
addition of stronger support beams to better position/support
the camera.
NOTE: [3.3.1 was installed
March 11/2016, current tests show improvements to axiom solver
as well as 5-finger solver. Be aware that 3.1 does not number
cameras properly.]

Note that the software error values have changed since the 2x
series.
In 2010 with the old wand (and version 1.7), .35 was considered
an excellent result.
With the new wand (and version 2.5/2.6), values around .20 were
common.
With 3x series, expect errors around .35 again. This is due
to the change in computation of error.
Recalibrate if your overall error exceeds .40. (See Camera
Calibration for more details).
Note, during Winter Quarter
Values between 2.6 and 3.0 were being obtained.
Once you have the basic capturing achieved, you can also
try finger capture. Finger capture is much easier since
Vicon Blade 2.6 and higher.
Note that you can clean data in Blade, Motion Builder and
Maya - select the technique you prefer. You are highly
encouraged to use Blade for cleaning up and fixing minor errors
(re-targeting is better done in motion builder).
Streaming now works with Motion Builder
2016 and has been fulled tested.
