STEP 1
In VTube-LASER window click on Scanner Algorithm label above the viewport window.
This loads the FARO Laser Line Probe Control window.
The alternative way to get into the FARO Laser Line Probe Control window is to click on Measure Setup in the Navigation Pane > Arm tab > Scanner Control button. |

STEP 2
Set the Scan Rate to 1/1.
- This value will allow the laser stripes to come into VTube-LASER as quickly as the FARO driver can send them.
STEP 3
Set the Scan Density to 1/16
- This value will reduce density of the points in the laser line returned to VTube-LASER.
- VTube-LASER removes some of points with two separate algorithms. First it uses a Maximum Number of Points Allowed in Cylinder Laser Stripe filter. Second it removes any points that are unnecessarily close to other points. So it works faster if the FARO driver removes some of those points in advance. Both scanning and calculation can be many times faster when the Scan Density is reduced to anything less than 1/1.

STEP 4
As of early 2017, we tend to prefer to use Automatic - HDR (High Dynamic Range) for as many materials as possible. According one of the top technicians at FARO, this is an acceptable approach for VTube-LASER because we are not scanning dense point clouds like other programs do. (We use 1/16 for scan density with the HD scanner.)
If you are scanning in a room with sunlight coming through the windows - then be sure to use the HDR mode because it is better able to adapt to sunlight and shadow.
The only time to change it to Automatic - Normal is when that mode gives better coverage of points on dull or blasted material.

STEP 5
Uncheck the Reflection Filter option.
- The FARO reflection filter makes FARO stop returning points when the scanner is moving, so scanning seems to stop and start even with the green button pressed.
- There doesn't seem to be significant benefit for tube scanning with this filter on - and VTube will remove spiked outliers automatically with the spike filter - so this filter is redundant.

STEP 6
Click on the OK button to exit the FARO Laser Line Probe window.
This completes the setup.
