NumericsConverter

Conversion methods between Unity vectory types and System.Numerics.Vector as extension methods

Getting Started

The recommended way of installation is through OpenUPM.

openupm add com.kuraiandras.numericsconverter

Or you can add it with a git dependency:

// For latest always
"com.kuraiandras.numericsconverter": "https://github.com/KuraiAndras/NumericsConverter.git?path=/NumericsConverter/Assets/NumericsConverter"

// For specific version
"com.kuraiandras.numericsconverter": "https://github.com/KuraiAndras/NumericsConverter.git?path=/NumericsConverter/Assets/NumericsConverter#2.0.1"

using NumericsConverter; // use this namespace for the exentsion methods
