The INCANG function returns the angle in radians between 2 vectors that are made from the positions of either 3 or 4 markers. If the vectors continue to rotate in the same direction past 180 degrees, then the angle returned increases beyond 180 degrees.
(Note: The initial value of INCANG is between 0 and 180, inclusive)

Arguments definition
|
Marker1 |
The name or argument number of a marker to be calculated. (the end point of the 1st vector) |
|
Marker2 |
The name or argument number of a marker to be calculated. (the start point of the 1st vector) |
|
Marker3 |
The name or argument number of a marker to be calculated. (the start point of the 2nd vector) •If omitted, then the Marker2 is applied. |
|
Marker4 |
The name or argument number of a marker to be calculated. (the end point of the 2nd vector) |
Formulation
The first value of INCANG is positive angle and the value of INCANG is the cumulative angle on the simulation.
Example
INCANG (body1.Marker1, Ground.InertiaMarker, body2.Marker1)
