BC correction table with 5D interpolation

Implementations§

Source§

impl BcCorrectionTable

Source

pub fn load<P: AsRef<Path>>(path: P) -> Result<Self, BcTableError>

Load a BC correction table from a binary file

Source

pub fn lookup( &self, bc: f64, bc_type: &str, mass: f64, length: f64, velocity: f64, ) -> f64

Look up a BC correction factor with 5D linear interpolation

§Arguments
  • bc - Published BC value
  • bc_type - “G1” or “G7”
  • mass - Bullet mass in grains
  • length - Bullet length in inches
  • velocity - Current velocity in fps
§Returns

Correction factor (multiply published BC by this value)

Source

pub fn lookup_with_caliber( &self, bc: f64, bc_type: &str, mass_grains: f64, caliber_inches: f64, velocity_fps: f64, ) -> f64

Get the BC correction factor for a given bullet and velocity This is a convenience method that estimates bullet length from mass and caliber

§Arguments
  • bc - Published BC value
  • bc_type - “G1” or “G7”
  • mass_grains - Bullet mass in grains
  • caliber_inches - Bullet caliber in inches
  • velocity_fps - Current velocity in fps
Source

pub fn version(&self) -> u32

Get table version

Source

pub fn total_cells(&self) -> usize

Get total number of cells in the table

Source

pub fn dimensions_str(&self) -> String

Get table dimensions as a string
