Hydrogen

Introduction

Library for generating a WebGL scene by using ThreeJS on the web for the Haskell programming language.

Short description

The Hydrogen uses the HFitUI library as the result of generating a WebGL scene. The WebGL scene is generated from a YAML file. This approach greatly simplifies the process of generating a WebGL scene in a Haskell with HFitUI library. Below is an example generation scene from YAML file code:

/*Generate by HScript from the HFitUI library*/
//Автоматически сгенерированный скрипт
//Приложение Hydrogen (0.0.1)
