We can get a 3D bone with a simple command like this: (ctrl+)Thigh ["Graphics3D"] enter image description here

or like this (ctrl+)bone ["Graphics3D"] enter image description here

Can we animate these objects ? For example, make the thigh turn a circle, or even make the skeleton do a squat exercise ?

Thank you very much.

{femur, skeleton} = Interpreter[
     "Graphics3D"] & /@ {"left femur", "skeleton"};

This is quite slow to initialize and for any change to ViewPoint for skeleton

 Show[bone, ViewPoint -> vp],
 {{bone, femur}, {femur, skeleton}},
 {{vp, Front, "View Point"},
  {Above, Below, Front, Back, Left, Right,
   {Above, Front}, {Above, Back},
   {Below, Front}, {Below, Back},
   {Left, Above}, {Right, Above},
   {Left, Below}, {Right, Below},
   {Left, Front}, {Right, Front},
   {Left, Back}, {Right, Back},
   {Above, Front, Left}, {Above, Front, Right}, 
   {Below, Front, Left}, {Below, Front, Right},
   {Above, Back, Left}, {Above, Back, Right},
   {Below, Back, Left}, {Below, Back, Right}}},
 SynchronousUpdating -> False]

Alternatively, you can set the ViewPoint to {x,y,z} and manipulate these variables


I though I read something about you could not rotate them, but…

As far as manual animation, in V11 I was able to draw a bone with:

AnatomyPlot3D[Entity["AnatomicalStructure", "LeftFemur"]]

and I could animate it manually.

Also, looking at the InputForm[] of the result, shows that it is drawn with a GraphicsComplex[] and there is a ViewPoint-> option, so you should be able to animate it programmatically.

  • $\begingroup$ Your code AnatomyPlot3D... didn't work on v11. I got these messages EntityValue::nodat: Unable to download data. Some or all results may be missing. AnatomyPlot3D::missmod: Unable to obtain a 3D model for Entity[AnatomicalStructure,LeftFemur]. $\endgroup$ Sep 27, 2016 at 17:28
  • $\begingroup$ Sorry Alan...that worked on my V11.0 Mac ElCap...I have seen a bunch of EntityValue[] errors that are basically DB timeouts...sometimes re-running it will succeed...I assume these are infrastructure configuration issues in the back-end (that WRI support is working on) $\endgroup$
