Detailed Description

Represents the source data used to build an navigation mesh tile.

This structure is used to marshal data between the Recast mesh generation pipeline and Detour navigation components.

See the rcPolyMesh and rcPolyMeshDetail documentation for detailed information related to mesh structure.

Units are usually in voxels (vx) or world units (wu). The units for voxels, grid size, and cell size are all based on the values of cs and ch.

The standard navigation mesh build process is to create tile data using dtCreateNavMeshData, then add the tile to a navigation mesh using either the dtNavMesh single tile init() function or the dtNavMesh::addTile() function.
