# About project
The library provides trajectory calculation for ballistic projectiles including air rifles, bows, firearms, artillery, and so on.
The 3DoF model that is used in this calculator is rooted in public C code of [JBM's calculator](https://jbmballistics.com/ballistics/calculators/calculators.shtml), ported to C#, optimized, fixed and extended with elements described in Litz's _Applied Ballistics_ book and from the friendly project of Alexandre Trofimov and then ported to Go.
This Python3 implementation has been expanded to support multiple ballistic coefficients and custom drag functions, such as those derived from Doppler radar data.
**[The online version of Go documentation is located here](https://godoc.org/github.com/gehtsoft-usa/go_ballisticcalc)**.
**[C# version of the package is located here](https://github.com/gehtsoft-usa/BallisticCalculator1), and [the online version of C# API documentation is located here](https://gehtsoft-usa.github.io/BallisticCalculator/web-content.html)**.

## RISK NOTICE
The library performs very limited simulation of a complex physical process and so it performs a lot of approximations. Therefore, the calculation results MUST NOT be considered as completely and reliably reflecting actual behavior or characteristics of projectiles. While these results may be used for educational purpose, they must NOT be considered as reliable for the areas where incorrect calculation may cause making a wrong decision, financial harm, or can put a human life at risk.
