What does Visual Studio 2012 use to open and view a *.obj 3D model?

Question

PHP

Studio 2012 has a built-in 3d editor. It easily opens models in .obj
Who knows what the studio uses to open a model and is it possible to use it somehow in your project?
It is clear that he most likely uses some kind of converter from obj to wpf. I wonder which one.

Answer 1

the spell must be read, then it will work:

... Thrice-cursed
sickness Get out the black disease
Go into the ground, into the ground
Under your feet, go under your feet
Get out the red shadow
Dry the dead grass
Go into the ground, into the ground
Under your feet, under your feet
Take out the wind of rubbish from the hut
Sweep the wind of rubbish from the hut
B go to the ground, to the ground
Go under your feet, under your feet Go
away behind the gate old woman, away!
Stitch empty eye sockets with hair Go to the ground, go
to the ground
Under your feet, go under your feet
The mirror will retell everything in the first
By the second, by the third
Let the root tooth fall out with blood The
fierce disease will
leave you
It will go under your feet, under your feet ...

Answer 3

Why so many concatenation operations? And a hodgepodge of single and double quotes? There are enough common single quotes everywhere...
