Unfortunately they grew as I just became accustomed to the AMR +format and still contain provisions due to some initial misconceptions on my +part (i.e. trying to handle incompletely refined grid cells being the severest +example). They were left in the library because they sometimes come in handy +when experimenting with AMR data (e.g. throwing away boundary cells for higher +order interpolation, etc.). Ultimately they should be discarded. + +All this is work in progress and still needs to be tweaked to work. It was +sufficient to generate the images in the papers I wrote, but I may have broken +one thing or the other when I made changes. So take these sources as they are +and expect some problems when using them. + +The grid stitching code can be found in AMRGridStitcher.hh and AMRGridStitcher.cc. +WriteStitchCells.cc and StitchCellWriter.hh, StitchCellWriter.cc is an example +for using it to write the stitch cells to a file. A description of the grid +stitching can be found in: + +Weber, G.H., Kreylos, O., Ligocki, T.J., Shalf, J.M., Hagen, H., Hamann, B. +and Joy, K.I. (2002), "Extraction of crack-free isosurfaces from adaptive +mesh refinement data," to appear in: Farin, G., Hagen, H. and Hamann, B., +eds., Hierarchical and Geometrical Methods in Scientific Visualization, +Springer-Verlag, Heidelberg, Germany. + +A pdf version of the paper is available at +http://graphics.cs.ucdavis.edu/~hamann/WeberKreylosLigockiShalfHagenHamannJoy2002.pdf + +Gunther H Weber (weber@informatik.uni-kl.de) |
