Centroid - Stage Precision

The centroid is the average center of a selected number of points, as the tracked points move the centroid will automatically update.

Coordinates

Name	Description
Position	This will move the object along X, Y and Z axis in the local space.
Scale	Scale of the coordinate system. To scale the Object check the settings under “Display”
Rotation	Rotation of the object along X, Y and Z axis.
Velocity	This is the speed of the object in the direction it is traveling along the X, Y and Z axis.
Acceleration	This is the rate of change of the velocity of the object.

Name	Description
Point Count	Number of points that make up the centroid.
Mode	Dampening – This is how smooth the movement of the centroid to a new center point when a tracking point is lost. Time Linear – This is a fade time in seconds that it takes for the centroid to move to a new center point when a tracking point is lost. Time Cubic
Damping	The higher the number the more the data is affected.
Time	The amount of time the set for the time linear and time cubic settings.

Name	Description
Link	This is where the assigned points can be selected to build the centroid.
Rel Position	This is the position of the selected point.
Tracked	This can be turned on and off. When on the points coordinates will be tracked.

Name	Description
Display Object	If ticked, the object will be visible in the scene. If un-ticked, the object will not be visible.
Display Label	When on, there will be a label displayed next to the object.
Locked	When un-ticked, it activates keyboard shortcuts – pressing ‘E’ allows you to move and ‘R’ rotate.
Object Colour	Double click the colour block and this will open a colour picker. This can be used to change the object display colour.
Viewport Scale	Dimensions of the object in the viewport in meters.
Display Trace	The trace is a trail that follows the tracker and shows the direction of movement. When un-ticked there will be no trace.
Trace Time	This determines how long the trace is displayed before it disappears.
Trace Colour	Double-clicking the colour box opens a colour picker with RGB (red, green, blue) and alpha control.
Display	This allows you to change the shape of the tracker – choosing between a cube, sphere or crosshair.
Radius	Distance from the center of the object to the edge of the circle in meters.

The object can be controlled and used as a node. The node is created by clicking and dragging the parameter on to the board.

Name	Description
Type	Input – The nodes input values are determined by incoming values from an external source. Output – The node is outputting data to another source.
Target Object	This is the object that will either be affected by the incoming values or output information.
Position	The directional XYZ values will be displayed here.
Rotation	The rotational XYZ values will be displayed here.
Enabled	When on, the parameter is active and enabled.
Display Colour	This colour block can be changed by changing the parameter.

Name	Description
Editable	When on, the node is editable.
Locked	When on, the node is locked into its position on the board.
