Summary0015769: BlankPoint: Blanking turns off too much points in the structured grid
DescriptionToo much points are turned off when using blankPoint method.
Steps To ReproduceLooking at the example available at : http://www.vtk.org/Wiki/VTK/Examples/Cxx/StructuredGrid/BlankPoint [^]
If we change the pointId in function BlankPoint from 27 to 1, then the points ID 0, 1 and cells Id 0, 1 are turned off.

The behaviour of point ID 1 is fine, the behaviour of cells Id 0 and 1 is fine as well. But the behaviour the point ID 0 is wrong. Indeed, we never asked the point ID 0 to be turned off.

This is a VTK related issue, not a ParaView one. Please report it on the VTK bug tracker (http://www.vtk.org/Bug/view_all_bug_page.php [^] , on the top-right combo box, choose VTK project instead of ParaView).
Thanks.

By the way the behaviour seems OK for me: if you turn OFF the point 1, it affects the visibility of the connected cells (0 and 1). As point 0 is only connected to cell 0, it will not be visible when drawing mesh cells as the cell 0 is blanked... but it does not mean the point 0 is blanked.

Yes I understand your explanation.
But in ParaView, if we change the representation in representation type combo-box from "surface" to "points", then the point 0 is not visible.

You are right, but it does not mean the point 0 is blanked either :)
The "points" representation display points of the geometry mesh cells (instead of the cells themselves). As the point 0 is not refered by any cell, it is not displayed.

How would you show all the points of a 2d structured mesh minus a defined (tiny) subset of them? Since my points are regularly spaced, I am not thinking about using a pure cloud of points.
In the example we discuss, how would you show ALL points except point ID 1?
I am trying to achieve that using blankPoint method but I may use the wrong approach and consequently wrongly assume I am facing a bug.

In ParaView you could use the Find Data dialog, find points "ID is 1", then check the "Invert selection" check box.
It will select all points but the one with ID=1. You can then extract the selection and will obtain a point cloud without the selected point.
