Best Practices

  • Light Pollution
  • For highest quality tracking keep ambient light to a minimum
  • Make sure the door is closed and the window is blocked
  • Only use the television for demonstration purposes, always turn off the television when recording motion capture data.
  • Evidence of light pollution can be seen when the tv is on. (The back wall turns from red to purple when mixed with the blue light from the television.)
  • Acting for the system
  • Always keep in mind the actors limb placement in relation to the system cameras.
  • The more cameras that have a clear line of site to each limb on the actors body at any given will allow for better tracking.
  • Allowing one joint to pass between the a cameras field of view and another joint can confuse the system as to which joint is which, for example crossing arms or feet. The result will be distorted and even possibly breaking the rig.
  • Open stage administration, connect the server and check the outline checkbox on the bottom of administration. In camera view, the outline of people which is used for data extracting is showed. Always try to keep outline clearly show the skeleton of the people will help the system have a good tracking state.
  • Tracking area
  • Actors within the system should stay approximately 1ft. in front of the camera line at all times.
  • Default tracking area 6.5 by 6.5 feet.
  • Tracking area can be set through administration. The larger the tracking area is, the less unstable the system is. 8-9 by 8-9 feet is good balance between performance and area size.
  • Attire
  • Actors should wear dark form fitting clothing.
  • Pants should not block the ankle.
  • People with long hair should make sure that it does not blend into their shoulders.
  • Above all make sure that all joints are clearly distinguishable to the system.
  • You might want to turn the TV off (If you are at the large mocap room). The actors/performers tend to look at TV while they act/perform, and this will affect the nature of their body movements.
