Hi

I consider Powertoys as drawing engine embedded in 3d modeling software about to create. 
I wonder how MVVM friendly PowerToys are? 

Ploting sphere is as easy as having

Code:

<visuals:SphereVisual3D CenterPosition="30 10 0" Radius="10" Material="s:64;Silver"/>

 
then let imagine I have collection of spheres dynamically added by users, so my ViewModel owns property encapsulating list of sphere's descriptors (ie size and location):

Code:

public ObservableCollection<SphereDescriptor> Spheres => _spheres;

where SphereDescriptor class is shaped like below:

Code:

class SphereDescriptor
{
  public LocationXYZ Position { get; } // don't know exact Sphere.CenterPostion's type
  public int Radius { get; }
}

 
and finally i'd like to have view defined like that:

Code:

<List ItemsSource={Binding Spheres}>
   <ItemTemplate>
           <visuals:SphereVisual3D CenterPosition="{Binding Position}" Radius="{Binding Radius}" Material="s:64;Silver"/>
   </ItemTemplate>
</List>

 Please notice Binding definition instead explicitly given values. 

So how MVVM friendly PowerToys are?
