esp::assets::MeshMetaData struct
#include <esp/assets/MeshMetaData.h>

Stores meta data for an asset possibly containing multiple meshes, materials, textures, and a hierarchy of component transform relationships.

As each type of data may contain a few items, we save the start index, and the end index (of each type) as a pair. In current implementation: instance mesh: meshes_ (1 item), textures_ (0 item), materials_ (0 item); gltf_mesh, glb_mesh: meshes_ (i items), textures (j items), materials_ (k items), i, j, k = 0, 1, 2 ...

Public types

using start = int
Start index of a data type in the global asset datastructure.
using end = int
End index of a data type in the global asset datastructure.
