## What it is
A C++ toolkit that converts large-scale 3D geospatial data such as OSGB and Shapefile into Cesium 3D Tiles format. It supports optional mesh simplification, Draco geometry compression, and KTX2 texture compression, with builds for Linux, macOS, and Windows.

## Use cases
- convert osgb to 3d tiles for cesium
- convert shapefile to 3d tiles
- compress b3dm tiles with draco
- prepare photogrammetry models for cesium streaming
- simplify mesh geometry for web 3d tiles
- batch convert large 3d gis datasets to 3d tiles

## When to choose
- you need to publish OSGB or Shapefile data as Cesium 3D Tiles
- you want fast, native conversion of large-scale 3D geospatial datasets
- you need Draco or KTX2 compression to reduce tile size

## When to avoid
- you need to convert formats other than OSGB or Shapefile
- you require a GUI-based conversion workflow
- you work with IFC/BIM data instead of terrain or photogrammetry meshes
