Figure 9From: Technologies for supporting high-order geodesic mesh frameworks for computational astrophysics and space sciencesStencil shapes in the plane. The top, middle, and bottom rows show the central, forward-biased, and backward-biased stencils, respectively. The principal zone is shown in red. Green, blue, and purple colors represent first, second, and third von Neumann neighbors of the principal zone, respectivelyBack to article page
