--- Begin Message ---Package: libvtk5 Version: 5.0.1-4 Severity: normal Hi! I found a bug in VTK library: it fails to correctly read two-dimensional PLOT3D solution (Q) files. Steps to reproduce the bug (using MayaVi, version 1.5-4): Extract the attached gzipped tar archive (which includes a test PLOT3D geometry+solution pair of files, along with a Fortran77 program that generates it) $ tar xvzf VTK_PLOT3D_testcase.tar.gz fakehurr_merid.q fakehurr_merid.xyz gen_fakehurr.f $ mayavi Using menus, select File -> Open -> PLOT3D file -> Multi-block file. As XYZ Co-ordinate file, select `fakehurr_merid.xyz'; as Q Solution file, select `fakehurr_merid.q'. In the configuration dialog window, select, say, density and momentum, and then click on the More Options button. In the detailed dialog window, check BinaryFileOn, DebugOn, DoNotReduceNumberOfOutputsOn, HasByteCountOn, MultiGridOn, TwoDimensionalGeometryOn; *un*check the other checkboxes (that is to say: AbortExecuteOn, ForceReadOn, IBlankingOn, ReleaseDataFlagOn). Select SetByteOrderToLittleEndian and click on the Ok button. Back in the configuration dialog window, click on the Re-read data file button. On stderr, various vtkPLOT3DReader debug messages appear, among which: : setting ErrorCode to 0 : Geometry number of grids: 1 : Geometry, block 0 dimensions: 31 41 1 : Q number of grids: 1 : Q, block 0 dimensions: 31 41 8 : setting ErrorCode to 20005 : Geometry and data dimensions do not match. Data file may be corrupt. VTK wrongly thinks that the Q block has 31x41x8 nodes, while it actually has 31x41x1 nodes (being two-dimensional). Hence the dimension mismatch between geometry and data. Trying to visualize data fails. For instance, using menus, select Visualize -> Modules -> ContourGridPlane: selecting Z-axis and checking Show Contours in the configuration dialog window fails to show any contours. Now the good news: I studied the vtkPLOT3DReader source code and detected the cause of this bug. A patch against VTK version 5.0.1 is attached: it fixes this bug for both vtkPLOT3DReader and vtkMultiBlockPLOT3DReader classes. While I was at it, I also discarded some useless variable loading in some PLOT3D functions, fixed a misleading debug message, fixed a macro definition in order to make it correct from a fluid dynamics point of view (even though this has currently no practical effect, since the extraneous multiplying factor is 1.0), and fixed some comments. OK, I hope this patch can be applied to vtk Debian package and also incorporated into the official VTK development branch. Finally the legal details. I'm not sure that my contribution to VTK is creative enough to grant copyright protection.
