There has been quite a few times when I have got emails from VTK Designer users asking me about a Mac version of VTK Designer. Now that we have VTK Designer 2 for Windows and GNU/Linux, it makes sense to try and provide a binary package for the Mac as well.
I borrowed a Mac Mini (which has Tiger) from a friend yesterday and I am giving “VTK Designer 2” for Mac a shot. My friend never saw the Mac as developer box, so he has no developer packages installed for the Mac. I just downloaded Qt for Mac, CMake for Mac. At the moment I am trying to get VTK compiled on Mac. Hopefully I should have a Mac version of VTK Designer 2 by the end of the day.
