Package: mayavi2 Version: 2.1.1-2 Severity: normal Hi!
I noticed a little problem in opacity management. Please note that I've recently upgraded mayavi2 from version 2.1.1-2 to version 2.1.1-2+b1, but I've seen the same issue with version 2.1.1-2. Let's consider (one more time!) 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 $ 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 * from menus, select Visualize -> Modules -> Surface (a blue square shows up in the TVTK scene) * rotate the TVTK scene (by moving the mouse with the left button pressed) I should only see at most three cube faces (if perspective theory is my friend...). Nonetheless, I can also see the remaining faces, behind the directly visible ones. Let me check the opacity settings: * in the MayaVi pane, double-click on Surface Mmmmh, Opacity is set to 1.0. Hence I should only see directly visible faces. Yet, I seem to have Superman X-ray view! ;-) Saving the scene to a PNG image, shows that the problem will affect visualization outputs, as well. It really seems I'm getting (partial) transparency, even when I do _not_ want it... :-( I think this is bug. -- 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 2.5.2-1 An interactive high-level object-o ii python-central 0.6.6 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+b1 Python bindings for VTK ii python-wxgtk2.6 2.6.3.2.2-2 wxWidgets Cross-platform C++ GUI t ii python2.5 2.5.2-3 An interactive high-level object-o mayavi2 recommends no packages. -- no debconf information -- To UNSUBSCRIBE, email to [EMAIL PROTECTED] with a subject of "unsubscribe".
