VBA: Sample Code to Rotate 3D Shapes During a Slide Show

• Microsoft PowerPoint 97 For Windows

SUMMARY

The following macro code enables you to have a three-dimensional (3-D) shape rotate along the X and Y axes during a slide show. This animation is started by creating an action button linked to the macro Rotate3d_Object.

Set up a macro to run during a slide show

   Sub Rotate3d_Object()

      ' Change this constant for different degrees or rotation.
      Const Increment As Integer = 5

      ' Use to control the for loop.
      Dim i As Integer
      Dim j As Integer

      ' A handle used to control the shape.
      Dim FirstShape As Shape

      ' A handle to reference the slide show window.
      Dim show as SlideShowWindow

      ' Two methods to set the active SlideShowWindow to the variable show:
      ' Set show = ActivePresentation.SlideShowSettings.Run
      ' -or-
      Set show = ActivePresentation.SlideShowWindow

      ' The first method allows you either to start the macro, which then
      ' automatically runs the slide show and the animations, or to link
      ' the macro to an object on the slide via an action setting. The
      ' animations would then run by clicking the object during a slide
      ' show. The second method is strictly an action setting, and
      ' functions only during a slide show.

      ' Get a reference to the shape. This assumes that the 3-D shape is in
      ' index position 2 on slide 1 of the presentation. That is, it is
      ' the second shape on the slide.
      Set FirstShape = ActivePresentation.Slides(1).Shapes(2)

      ' The RotationY and RotationX commands can rotate an object only
      ' from -90 degrees to 90 degrees. Also, it rotates to a specific
      ' point on a compass: if you rotate along the y axis to 45 degrees,
      ' the shape is now 45 degrees from dead center.
      For i = -45 To 45 Step Increment

         ' Rotate the shape to the degree specified.
         FirstShape.ThreeD.RotationY = i
         FirstShape.ThreeD.RotationX = i

         ' Refresh the slide. This step is needed to redraw the screen
         ' after the rotation step; Otherwise, the animation effect is
         ' invisible.
         show.View.GotoSlide 1

      Next i

      For i = 45 To -45 Step -Increment

         FirstShape.ThreeD.RotationY = i
         FirstShape.ThreeD.RotationX = i

         ' Refresh the slide.
         show.View.GotoSlide 1
      Next i

   End Sub
