At Reference Signal Value

Captures the value of a given expression when a given reference signal expression achieves a certain value (reference signal value).

Figure 1. Response Type – At Reference Signal Value
Input Description
Response Expression The function that is to be computed.
Reference Signal Expression The function at which the Response expression is desired.
Reference Signal Value A value of Reference Signal Expression at which Response expression must be computed.
Reference Signal Tolerance A small interval around the desired Reference Signal Value required for computation.

In the above example, the response variable captures the value of the expression that measures difference in YAW positions when the Reference signal (measuring angular rotation between 2 markers) value is zero.
