## Description

This project is a React-based WebGL renderer that enables the creation of three-dimensional scenes using a declarative, component-driven architecture. It functions as a bridge between a component-based user interface library and a low-level graphics engine, allowing developers to manage lights, cameras, and geometry as standard elements within a reactive tree structure.

The library distinguishes itself by treating the scene graph as a declarative hierarchy that synchronizes directly with application state and lifecycle events. It utilizes a custom reconciler to map component updates to object mutations, while a reflection-based system automatically binds component properties to underlying graphics objects. By integrating directly with the animation frame cycle, it ensures that visual updates remain synchronized with the render loop.

Beyond core rendering, the project provides a normalized event system that translates pointer interactions into raycasting intersections for 3D objects. It supports the development of consistent graphical content across desktop and mobile browsers through a unified programming model, while using context-based patterns to manage scene-specific instances like cameras and renderers.
