title: WPF animation of multiple 3D objects doing multiple transforms each
body: <p>I'm working on a WPF 3D project where I can have multiple (1 - 20'ish) ModelVisual3D objects being moved around the scene via animation.  Each ModelVisual3D has both a RotateTransform3D and a TranslateTransform3D applied to it each move.  And each ModelVisual3D object moves independently of each other.</p>
  
  <p>So right now in order to do this, each time I want to move objects around, I spin through each ModelVisual3D and setup a double animation for both its rotation and its translate transform movement.  Then call the BeginAnimation() on both transforms (for each object).  </p>
  
  <p>So that means, if I have 20 ModelVisual3D objects, I'll end up calling BeginAnimation() on 40 different transform objects...each time I need to move them.</p>
  
  <p>This performs ok, but it seems like there should be a better way.  Is there something where I can group multiple transforms together for multiple ModelVisual3D objects, into one "transform group" object, and then call Begin on that?</p>
  
  <p>Also, I looked at using the storyboard object, but I'm doing this all in C# (very little static xaml going on here, most of the UI is dynamically created).  The storyboard object seems to be able to only be used for a single ModelVisual3D object.  So best case, I would be down to 20 storyboard objects that I call BeginAnimation on.</p>
  
  <p>Or is what I'm doing the best thing to do?</p>
