Changing a few interfaces is manageable. Removing support for the entire GUI system is much more catastrophic. If this were a democracy I would stage a filibuster and force a super-majority. :-) <div><br></div><div>As it is, I will happily abide by any decision by the ARB, but I strongly urge that they make an explicit decision and announce it, rather than just do it by default or allow support to erode away. <div>

<br>I am saying we're making a bunch of changes anyhow, and applications are going to have to make lots of changes to adapt to them anyhow... and because of this, now is the perfect opportunity to make breaking changes, so that apps that need to adapt only need to do it once, and then we position VTK for better things in the future.

<div><br></div><div>Tcl wrapping, even if removed from VTK itself, could be done in a separate project, from the outside, after the fact. That's how ActiViz works for C# wrapping: which is another thing that will have to adapt to this new VTK if it wants to survive. To the best of my knowledge, nobody has spent any effort making sure ActiViz is still going to work flawlessly with the new VTK. That'll be something for somebody's to do list after the dust settles here.</div>

<span style="font-size:13px;font-family:arial,sans-serif">vtk3DWidget </span>being renamed. Despite it being an old generation widgets that we don't recommend folks derive from, but the fact remains that there are a few widgets in VTK that derive from it. There are a lot of widgets in Slicer (<20) and VolView (>10) that derive from it. These are examples from just 2 applications.</div>
<div><br></div><div>I don't support Tcl wrapping being dropped. There are still a lot of apps under active development out there relying on VTK being wrappable from Tcl (BioImageSuite, VolView, SCIRun, MIPS to name a few). It hasn't been long since Slicer made the switch either.</div>
<div><br></div><div>These are all large applications, with a large user base and important customers of VTK. Don't you think a stand that: "If these applications want to continue using VTK, they shouldn't upgrade" is a bit harsh. </div>
