◆ AltitudeOfBarometerFt()

Builder & lob::Builder::AltitudeOfBarometerFt ( double value )

inline

Sets the atmosphere reference associated with ballistic coefficient.

Parameters

type	The atmosphere reference type.

Returns: A reference to the Builder object.

◆ BCDragFunction() [1/2]

Builder & lob::Builder::BCDragFunction ( DragFunctionT type )

inline

Sets the drag function associated with ballistic coefficient.

Note: Does not clear a table loaded via MachVsDragTable, BCVelocityBands, or SplineCoefficients; those override the drag function at Build time. If multiple drag sources are configured, the last call wins regardless of order. Call Reset to return to a standard drag function.

Returns: A reference to the Builder object.

◆ BCDragFunction() [2/2]

Builder & lob::Builder::BCDragFunction ( LobDragFunctionT type )

inline

Sets the drag function associated with ballistic coefficient.

Note: Does not clear a table loaded via MachVsDragTable, BCVelocityBands, or SplineCoefficients; those override the drag function at Build time. If multiple drag sources are configured, the last call wins regardless of order. Call Reset to return to a standard drag function.

Parameters

type	The drag function type.

◆ BCVelocityBands() [1/5]

Builder & lob::Builder::BCVelocityBands	(	const float *	pfps,
		const float *	pbcvs,
		size_t	size )

inline

Loads ballistic coefficients measured at multiple velocities.

A projectile's effective BC varies with velocity. Supplying BCs at several velocities tailors the reference drag function to better fit the projectile's actual velocity-dependent drag.

Note: The BCs use the same units as BallisticCoefficientPsi and respect the atmosphere reference set via BCAtmosphere.

Warning: The caller must keep pfps and pbcvs valid until Build is called. The builder copies no data; the pointers are referenced during Build().

Parameters

pfps	Pointer to an array of velocity values in fps.
pbcvs	Pointer to an array of associated BC values.
size	The number of fps-BC pairs in the table. Must be at least 2 and at most 16; velocities must be positive and strictly increasing, BCs positive, and the highest velocity below Mach 5.

Returns: A reference to the Builder object.

template<size_t N>

Builder & lob::Builder::BCVelocityBands	(	const std::array< float, N > &	fps,
		const std::array< float, N > &	bcvs )

inline

Loads ballistic coefficients measured at multiple velocities.

A projectile's effective BC varies with velocity. Supplying BCs at several velocities tailors the reference drag function to better fit the projectile's actual velocity-dependent drag.

Note: The BCs use the same units as BallisticCoefficientPsi and respect the atmosphere reference set via BCAtmosphere.

Warning: The arrays must remain valid until Build is called; the builder copies no data and references them during Build(). Temporaries are rejected at compile time.

Template Parameters

N	The number of fps-BC pairs in the table. Must be at least 2 and at most 16; velocities must be positive and strictly increasing, BCs positive, and the highest velocity below Mach 5.

Parameters

fps	Reference to an array of velocity values in fps.
bcvs	Reference to an array of associated BC values.

Returns: A reference to the Builder object.

Builder & lob::Builder::MachVsDragTable	(	const float *	pmachs,
		const float *	pdrags,
		size_t	size )

inline

Loads a custom Mach vs Drag table for the projectile.

This is a direct alternative to using a ballistic coefficient and a reference drag function.

Note: If the table does not span Mach 0..5 it is extrapolated; if extrapolation would produce invalid drag, Build returns ErrorT::kMachDragTableInvalid — pad the table with explicit entries at 0 and/or 5.0 to define the desired edge behavior.

Warning: The caller must keep pmachs and pdrags valid until Build is called. The builder copies no data; the pointers are referenced during Build().

Parameters

pmachs	Pointer to an array of mach values.
pdrags	Pointer to an array of associated drag values.

Builder & lob::Builder::SplineCoefficients ( const float * pcoefs )

inline

Loads precomputed native spline coefficients for the drag curve.

Directly sets the 60 coefficients used by the solver, bypassing Mach-vs-drag table fitting and BC scaling. This is the lowest-level drag input, useful for round-tripping a previously built context or importing coefficients from another lob instance. The array is drags as stored in LobContext.drags.

Note: This overrides any drag function, custom table, or BC bands; the last drag-setting call wins. Call Reset to return to a standard drag function.

Warning: The caller must keep pcoefs valid until Build is called. The builder copies no data; the pointer is referenced during Build().

Parameters

◆ WindProfile() [1/3]

Builder & lob::Builder::WindProfile	(	const LobWindPoint *	ppoints,
		size_t	count )

inline

Loads a downrange wind profile for the projectile.

Point 0 sets the muzzle wind; all points are validated, normalized to the fixed 1-ft reference, resolved into the shooting frame, and stored as solver-ready nodes. A NaN measurement height assumes measurement at the 1-ft reference. The last wind-setting call wins: this overrides any uniform wind heading/speed, and those override this.

Warning: The caller must keep ppoints valid until Build is called. The builder copies no data; the pointer is referenced during Build().

Parameters

ppoints	Pointer to an array of wind profile points. First range must be 0 with strictly increasing whole-foot ranges; headings finite degrees, speeds finite mph, heights positive or NaN.
count	The number of points. Must be 1..LOB_WIND_POINTS.

inline

Loads a downrange wind profile for the projectile.

A NaN measurement height assumes measurement at the 1-ft reference. The last wind-setting call wins: this overrides any uniform wind heading/speed, and those override this.

Warning: The array must remain valid until Build is called; the builder copies no data and references it during Build(). Temporaries are rejected at compile time.

Template Parameters

N	The number of wind profile points. Must be 1..LOB_WIND_POINTS.

Parameters

points Reference to an array of wind profile points.

Returns: A reference to the Builder object.

◆ WindShearExponent()

Builder & lob::Builder::WindShearExponent ( double value )

inline

Sets the Hellmann shear exponent for wind profile height scaling.

Wind shear follows the power law with this exponent; scaling is off unless opted in with a nonzero value (0 disables it exactly). Defaults to 0 when unset. Typical values when enabling: open water 0.10, open grassland 0.143, farmland/crops 0.20, suburban 0.25, forest/urban 0.30.
