As a consequence to bug #478359, the SelectOutput filter was
added to mayavi2 (thanks!).
I noticed a (temporary) visualization glitch while using it.
Let's (once again!) consider the tiny test case I prepared for bug
#400406 (see  and ).
$ tar xvzf vtk-multiblockPLOT3D-bug-test.tar.gz
gen_tinyplot3d.f tiny.q vtk-multiblockPLOT3D-bug-test.tar.gz
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'
* in the property dialog window, 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; click on the OK button
* from menus, select Visualize -> Filters -> Select Output
* 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) and zoom out (by moving down the mouse with the right button
* in the MayaVi pane, click on SelectOutput and drag the slider in
order to select a block different from the first (e.g.: the last one)
The visualization no longer shows a cube!
I can only see a part of the cube, as if an invisible plane cut it
into two chunks, only one of which stays visible.
* rotate or drag or zoom the TVTK scene (even of a very little
quantity) and the problem goes away (i.e.: the full cube is again
I think this is a bug, I don't know if it's caused by MayaVi2, or by
