Minimum C-ABI trajectory step_size, in milliseconds (0.1 ms = 0.0001 s).

Functions

ballistics_calculate_trajectory^⚠

Calculate a trajectory through the C ABI.

ballistics_calculate_trajectory_with_drag_table^⚠

ballistics_calculate_trajectory with a caller-supplied custom drag deck (Cd vs Mach, e.g. Hornady CDM / Doppler-radar data). The deck REPLACES the G-model + BC for drag: bc_type/bc_value are ignored, and the retardation denominator becomes the projectile’s sectional density (mass and diameter in inputs must therefore be positive). Mach values must be strictly ascending with at least 2 points and finite positive Cd; outside the deck’s Mach domain the nearest endpoint Cd is held.

ballistics_calculate_zero_angle^⚠

Calculate the zero angle for a target distance through the C ABI.

ballistics_calculate_zero_angle_with_drag_table^⚠

ballistics_calculate_zero_angle with a caller-supplied custom drag deck (Cd vs Mach, e.g. Hornady CDM / Doppler-radar data). The deck REPLACES the G-model + BC for drag: bc_type/bc_value are ignored, and the retardation denominator becomes the projectile’s sectional density (mass and diameter in inputs must therefore be positive). Mach values must be strictly ascending with at least 2 points and finite positive Cd; outside the deck’s Mach domain the nearest endpoint Cd is held. Pair this with ballistics_calculate_trajectory_with_drag_table using the same deck to fly the solved angle — the two exports share identical deck semantics.

ballistics_free_monte_carlo_results^⚠

Release Monte Carlo results allocated by either Monte Carlo C entry point.

ballistics_free_trajectory_result^⚠

Release a trajectory result allocated by ballistics_calculate_trajectory.

ballistics_get_version

ballistics_monte_carlo^⚠

Run a Monte Carlo simulation through the C ABI.

ballistics_monte_carlo_with_direction_std_dev^⚠

Run a Monte Carlo simulation with independent wind-direction uncertainty through the C ABI.
