Текущие нормали объекта ткани.
This gives you read access to the normals of the cloth object, so you can analyse it's current simulation state. Note that the normal indices may not necessarily correspond to the indices of the source mesh - especially when triangle stripping or UV seams are used in the source mesh (ie, multiple indices for the same vertex), cloth vertices will be different, as the cloth simulation only uses a single index for each vertex.
