Computer
- Do not download or install any software on the Vicon computer. ALL post processing must be done on your own machine.
  - This is a shared machine that takes a lot of processing power to run the Vicon system and we need to preserve it’s RAM for only that purpose.
Objects/bodies
- Don’t place markers on a body symmetrically or else Vicon can’t tell the body’s orientation along the symmetric axis
- Vicon can track multiple bodies; however, you have to do one of the following first:
  - Place the tracking markers in distinguishable ways to be able to differentiate the bodies being tracked or
  - Use the Vicon swarm package to track multiple identical bodies
Cameras
- You need at least 3 cameras to triangulate a body in space but you should have more because sometimes some cameras randomly drop some of the markers they’re tracking.
- It is a good idea to have the cameras warm up for 30 minutes because the rise in temperature will change it’s measurement precision.
Software
- You can mask objects with the software that you cannot physically remove from the space. Vicon will cover whatever pixels you don’t want to see
  - When masking, don’t have the object you’re tracking in the camera’s view or else you’ll mask the object you’re trying to track
- When calibrating/creating objects, the orientation of space in the tracker software is as follows: red is for the x-axis, green is for the y-axis, blue is for the z-axis
