In ParaView 2.6, you do this with the icon that looks like a ruler. It is a line source. You place the ends of the line on a surface by hitting the 'p' key. The length is displayed right below the x,y, and z of point 1 and point 2 (on the Parameters tab).
PV 3.0 has a line source, but 1) you cannot place the ends easily on the top of a surface, and 2) it does not display the length of the line. |

I am changing this to High priority. We have had multiple requests that we have some type of ruler function. We need to at least implement either this feature, or 5422. |

Change line source to show length information somewhere. |

I'm pretty sure this is messing up the cube axis. Thus, asking for feedback on this bug.
Please run exactly as follows:
* Client/server - 6 servers. XP client.
* Open disk_out_ref.exo. Apply.
* Sources/ Ruler. (Don't hit apply)
* On bottom of cylinder, hit a 'p'.
* On top of cylinder, hit a 'p'.
(Note, it would sure be nice to document somehow that you could hit a p here.)
(Note, it would sure be nice to auto-accept here.)
* Apply.
* Display tab/ Show cube axes. The axes are located inside of the cylinder. |

Ah-hah. Lots of the junk above doesn't have to be done - the cube axes for the ruler is always weird. Turns out that it is putting the cube axes around the ruler itself. Does this make sense - should we just leave it, or should we turn off the Show Cube Axes for the ruler (and does that make sense)? |

Berk was suggesting we don't create any representation for the ruler. In otherwords, the display tab will never be enabled for the ruler, hence one will never see the cube-axes. Does that work?
I am guessing, however, the cube-axes has issues dealing with 1D data. So that is a bug we'd surely want to fix at some point. |

We can no longer apply cube-axes to the ruler. |

Very nice.
Now, when we turn on the ruler, and hit Apply (the button goes green), a seperate window opens up - with only the ruler in it.
XP client/ 6 pvservers
Open can.exo, apply.
Sources/ Ruler/ apply. |

Oh yes - when you close the separate window, PV crashes. |

* vtkLineRepresentation was not passing the renderer to the internal
representations, consequently, when the view was destroyed the internal
representations had a dangling pointer which led to segfaults.
* pqDisplayPolicy was create a new render view even when the render view could
not show the current source. This was resulting the a new 3D view being
created when a ruler source was created. Fixed that.

Great new feature.
Tested local client. Blackrose is down. |
