Adaptive Mesh Refinement (AMR) grids are particularily efficient to mitigate the tension between numerical accuracy and computational cost. The Visualization Toolkit (VTK) offers data structures and algorithms to treat 2D and 3D AMR meshes, either "patch-based" or as binary trees. This paper summarizes our extension of the former capability to the case of generic subdivision and arbitrary rectilinear geometry, using an optimized, generic tree traversal technique together with a fast dual grid construction.
