Figure 4From: Technologies for supporting high-order geodesic mesh frameworks for computational astrophysics and space sciencesStep operators on the mesh. The three unshaded to shaded step operators shown are used to walk the sector with its ghost t-faces. The step is from the vertex-face pair \(v_{i}\), \(t_{i}\) to \(v_{f}\), \(t_{f}\). The shaded to unshaded steps are obtained by switching the origin and destination vertex-face pairsBack to article page
