                                                          One of the
                                                          important
                                                          features of
                                                          this software
                                                          is the ability
                                                          to click on
                                                          elements of
                                                          the 3D view to
                                                          perform
                                                          actions or
                                                          view
                                                          information.
                                                          This works
                                                          perfectly on
                                                          Windows and
                                                          Linux, but
                                                          does not work
                                                          on Macs. I
                                                          believe that
                                                          this is due to
                                                          an internal
                                                          bug in the Mac
                                                          version of
                                                          VTK. We use
                                                          the
vtkJoglPanelComponent to embed the 3D view into our Java application.<br>
                                                          <br>
                                                          Here is the
                                                          code that I
                                                          use to pick
                                                          items (where
                                                          renderWindow
                                                          is a
vtkJoglPanelComponent):<br>
                                                          <br>
                                                                 
                                                          renderWindow.getComponent().ad<wbr>dMouseListener(new
                                                          MouseAdapter()

                                                                  });<br>
                                                          <br>
                                                          The first bug
                                                          is that the y
                                                          value of
                                                          getRenderWindowInteractor().Ge<wbr>tEventPosition()
                                                          is just flat
                                                          out wrong on
                                                          the Mac
                                                          (correct on
                                                          Windows and
                                                          Linux). For
                                                          example, if I
                                                          click near the
                                                          top of my
                                                          window with
                                                          height 700, if
                                                          will give me a
                                                          y value that
                                                          is greater
                                                          than 1300! It
                                                          should
                                                          actually be
                                                          very small, as
                                                          y should be
                                                          zero at the
                                                          top of the
                                                          window and 700
                                                          at the bottom
                                                          of the window.
                                                          I can get
                                                          around this,
                                                          and make it
                                                          match the
                                                          position on
                                                          Linux/Windows
                                                          with the
                                                          following fix
                                                          using the
                                                          mouseEvent (e)
                                                          and the height
                                                          of the 3D view
                                                          component:<br>
                                                          <br>
                                                                       
                                                            int height =
renderWindow.getComponent().ge<wbr>tHeight();<br>
                                                                       
                                                            int calcY =
                                                          (height -
                                                          e.getY()) - 1;<br>
                                                                       
                                                            int x =
                                                          e.getX();<br>
                                                                       
                                                            int y =
                                                          calcY;<br>
                                                          <br>
                                                          Now when I
                                                          click on a
                                                          location in
                                                          the 3D viewer,
                                                          the x/y
                                                          coordinates
                                                          match the
                                                          results on
                                                          Linux/Windows.
                                                          But picking
                                                          actors still
                                                          doesn't work.
                                                          Instead, VTK
                                                          thinks that I
                                                          have clicked
                                                          somewhere
                                                          roughly
                                                          between where
                                                          I actually
                                                          clicked and
                                                          the bottom
                                                          left corner.
                                                          So if I click
                                                          on the top
                                                          right corner
                                                          of the viewer,
                                                          it thinks that
                                                          I clicked in
                                                          the middle. If
                                                          I click on the
                                                          top left, if
                                                          thinks that I
                                                          clicked middle
                                                          left. If I
                                                          click on the
                                                          middle of the
                                                          viewer, it
                                                          thinks that I
                                                          clicked 1/4 up
                                                          and right of
                                                          the lower left
                                                          corner. I have
                                                          posted a video
                                                          which
                                                          demonstrates
                                                          this bug:<br>

                                                          <br>
                                                          In this video,
                                                          whatever actor
                                                          is clicked
                                                          turns red.
                                                          This works as
                                                          expected on
                                                          Windows/Linux,
                                                          both with and
                                                          without the
                                                          x/y fix
                                                          mentioned
                                                          above. Without
                                                          the previous
                                                          fix on a Mac,
                                                          the behavior
                                                          is similar but
                                                          centered
                                                          around the top
                                                          left corner
                                                          and sometimes
                                                          doesn't detect
                                                          clicks at all
                                                          (due to y
                                                          values which
                                                          make no
                                                          sense).<br>
                                                          <br>
                                                          Any ideas what
                                                          could be going
                                                          on? I have
                                                          experienced
                                                          this behavior
                                                          on all 4 Mac's
                                                          on which I
                                                          have tried the
                                                          software.<br>
