pcd viewer

This library is a visualization React module developed to efficiently render data output from the module pcd-lod, which converts point cloud data into an LOD (Level of Detail) format for efficient drawing. The purpose of this module is to facilitate effective visualization of this data on web browsers.

It includes a collection of components using React Three Fiber, allowing for easy integration into any React project.
