◆ BKE_mesh_new_from_object()

Mesh * BKE_mesh_new_from_object	(	Depsgraph *	depsgraph,
		Object *	object,
		bool	preserve_all_data_layers,
		bool	preserve_origindex )

Create new mesh from the given object at its current state. The caller owns the result mesh.

If preserve_all_data_layers is true then the modifier stack is re-evaluated to ensure it preserves all possible custom data layers.

Note: Dependency graph argument is required when preserve_all_data_layers is true, and is ignored otherwise.

Mesh * BKE_mesh_new_from_object_to_bmain	(	Main *	bmain,

This is a version of BKE_mesh_new_from_object() which stores mesh in the given main database. However, that function enforces object type to be a geometry one, and ensures a mesh is always generated, be it empty.

Note: We disable auto texture space feature since that will cause texture space to evaluate differently for curve and mesh, since curves use control points and handles to calculate the bounding box, and mesh uses the tessellated curve.
