const Feature& Magnum::SceneGraph::FeatureGroup<dimensions, Feature, T>::operator[](std::size_t index) const

This is an overloaded member function, provided for convenience. It differs from the above function only in what argument(s) it accepts.

template<UnsignedInt dimensions, class Feature, class T>
FeatureGroup<dimensions, Feature, T>& Magnum::SceneGraph::FeatureGroup<dimensions, Feature, T>::add(Feature& feature)

Add a feature to the group.

Returns Reference to self (for method chaining)

If the features is part of another group, it is removed from it.
