void nav_survey_poly_osam_setup_towards ( uint8_t  FirstWP,
uint8_t  Size,
float  Sweep,
int  SecondWP 
)

Setup "dynamic" polygon survey with sweep orientation towards a waypoint.

Computes the sweep orientation angle from the line FirstWP-SecondWP. If you pass zero for Size and/or Sweep it will use the global Poly_Size and Poly_Sweep variables respectively (which can be changed via telemetry/settings).

Parameters
FirstWPfirst waypoint/corner of the polygon
Sizenumber of waypoints/corners used to define the polygon, if zero uses Poly_Size
Sweepdistance between scan lines, if zero uses Poly_Sweep
SecondWPsecond waypoint towards which the sweep orientation is computed
