Detailed Description

template<typename T, std::size_t Dim = 3, typename VertexTraits = traits::DefaultVertexTraits<T>, typename EdgeTraits = traits::DefaultEdgeTraits<T>, typename FaceTraits = traits::DefaultFaceTraits<T>>
template<bool Const = false>
class OpenABF::HalfEdgeMesh< T, Dim, VertexTraits, EdgeTraits, FaceTraits >::WheelIterator< Const >

Iterator for the edges of a vertex's wheel.

Walks the half-edge linked-list around a vertex (edge->pair->next), yielding only non-boundary edges. Multi-pass safe: constructing a new WheelIterator from the same vertex edge always starts at the beginning.

Template Parameters

Const

If true, is a const iterator
