BKE_editmesh_loop_tangent_calc()

void BKE_editmesh_loop_tangent_calc	(	BMEditMesh *	em,
		bool	calc_active_tangent,
		const char(*)	tangent_names[MAX_CUSTOMDATA_LAYER_NAME],

#BKE_mesh_calc_loop_tangent, same logic but used arrays instead of BMesh DNA, RNA and .blend access.

Note

This function is not so normal, its using BMesh.ldata as input, but output's to Mesh.corner_data. This is done because CD_TANGENT is cache data used only for drawing.
