Detailed Description

Basic struct to adapt a FMeshDescription for use by GeometryProcessing classes that template the mesh type and expect a standard set of basic accessors For example, this adapter will let you use a FMeshDescription with GeometryProcessing's TMeshAABBTree3 See also the Editable version below

Usage example – given some const FMeshDescription* Mesh: FMeshDescriptionAABBAdapter MeshAdapter(Mesh); // adapt the mesh TMeshAABBTree3<const FMeshDescriptionTriangleMeshAdapter> AABBTree(&MeshAdapter); // provide the adapter to a templated class like TMeshAABBTree3
