3D model of the Stanford Armadillo

Details

Computer graphics 3D test model developed by Venkat Krishnamurthy and Marc Levoy in 1996 at Stanford University. The model consists of data describing 345,944 triangles determined by 3D scanning a toy resembling a humanoid armadillo. This model and others were scanned to test methods of range scanning physical objects.
The original toy depicted the Soccadillo monster from the television series Mighty Morphin' Power Rangers.

Basic Examples (2) 

Retrieve the model:

In[1]:=
ResourceData[\!\(\* TagBox["\"\<Stanford Armadillo\>\"", #& , BoxID -> "ResourceTag-Stanford Armadillo-Input", AutoDelete->True]\)]
Out[1]=

Summary properties:

In[2]:=

Out[2]=

Scope & Additional Elements (1) 

Find the minimum volume ball that encapsulates the mesh:

In[3]:=
bound = BoundingRegion[ResourceData[\!\(\* TagBox["\"\<Stanford Armadillo\>\"", #& , BoxID -> "ResourceTag-Stanford Armadillo-Input", AutoDelete->True]\)], "MinBall"]
Out[3]=
In[4]:=
Show[{ResourceData[\!\(\* TagBox["\"\<Stanford Armadillo\>\"", #& , BoxID -> "ResourceTag-Stanford Armadillo-Input", AutoDelete->True]\)], Graphics3D[{Opacity[0.5], bound}]}]
Out[4]=
