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.
