Package: mayavi2 Version: 2.1.1-2 Severity: normal Hi!
I'm unable to read any block, except the first, in multiblock PLOT3D files. I can reproduce this bug with any multiblock PLOT3D file having more than one block. For instance we can consider the test case I prepared for bug #400406 (see [1] and [2]). [1] http://bugs.debian.org/400406 [2] http://bugs.debian.org/cgi-bin/bugreport.cgi/vtk-multiblockPLOT3D-bug-test.tar.gz?bug=400406;msg=5;att=1 That test case is based on a little PLOT3D grid ('tiny.xyz') and solution ('tiny.q'), generated by a simple Fortran program ('gen_tinyplot3d.f') on a little-endian machine. The PLOT3D grid is composed of 5 blocks, each one of which consists of a single cubic cell. $ tar xvzf vtk-multiblockPLOT3D-bug-test.tar.gz $ ls gen_tinyplot3d.f tiny.q vtk-multiblockPLOT3D-bug-test.tar.gz list_plot3d.py tiny.xyz $ mayavi2 The main window shows up. * from menus, select File -> Load data -> PLOT3D file * as XYZ Co-ordinate file, select `tiny.xyz' * as Q Solution file, select `tiny.q' * select PLOT3D:tiny.xyz, tiny.q in the MayaVi pane * in the PLOT3DReader tab (inside the object editor), check "Binary file", "Do not reduce number of outputs", "Has byte count", and "Multi grid"; *un*check "Force read", "I blanking", and "Two dimensional geometry"; select "little_endian" Byte order * in the Reader tab, click on the "Update Reader" button OK, now we are ready to visualize the data... * from menus, select Visualize -> Modules -> Surface (a blue square shows up in the TVTK scene) * from menus, select Visualize -> Modules -> Axes (coordinate ranges show up, confirming that we are seeing the first grid block, where 1 <= X <= 2) OK, back to the PLOT3DReader tab: where's the option to select which grid blocks I want to load?!? I really cannot find it... I would like to have a means to decide which grid blocks will be loaded (e.g.: I want to load block 1, 2, and 4, but not the remaining two), so that a number of PLOT3D:tiny.xyz, tiny.q objects are automatically created, each one corresponding to one of the requested grid blocks (e.g.: three objects are created, corresponding to blocks 1, 2, and 4). Please note that this decision may be taken only after PLOT3D properties (such as "Binary file", "Has byte count", and so forth) have been specified, or otherwise the total number of blocks present in the PLOT3D file will not be computed correctly... -- System Information: Debian Release: lenny/sid APT prefers testing APT policy: (500, 'testing') Architecture: amd64 (x86_64) Kernel: Linux 2.6.24-1-amd64 (SMP w/2 CPU cores) Locale: LANG=en_US.UTF-8, LC_CTYPE=en_US.UTF-8 (charmap=UTF-8) Shell: /bin/sh linked to /bin/bash Versions of packages mayavi2 depends on: ii libc6 2.7-10 GNU C Library: Shared libraries ii python 2.4.4-6 An interactive high-level object-o ii python-central 0.6.5 register and build utility for Pyt ii python-enthought-traits 2.0.4-2 Manifest typing and reactive progr ii python-enthought-traits-ui 2.0.4-2 User interface related modules for ii python-numpy 1:1.0.4-7 Numerical Python adds a fast array ii python-pkg-resources 0.6c8-3 Package Discovery and Resource Acc ii python-vtk 5.0.4-1 Python bindings for VTK ii python-wxgtk2.6 2.6.3.2.2-2 wxWidgets Cross-platform C++ GUI t ii python2.4 2.4.5-1 An interactive high-level object-o mayavi2 recommends no packages. -- no debconf information -- To UNSUBSCRIBE, email to [EMAIL PROTECTED] with a subject of "unsubscribe".
