Windows 10 Mixed Reality Viewer
The Windows Fall Creators
Update installed the Mixed Reality Viewer app on your Windows 10 machine, even
if you didn’t know it was there.
Do a quick Cortana search and open the Mixed Reality Viewer app to play around with 3D models – either one you have created in Paint 3D or downloaded from Microsoft’s library of thousands of 3D models.
If you own one of Microsoft’s Windows Mixed Reality partner headsets or want to start playing around with 3D and mixed reality development, this app is your way to start a possible new career!
Of course, if your PC has not been updated with the Windows Fall Creators Update you can still ask Cortana to open Mixed Reality Viewer but she will offer you the 3D Viewer, which is an app from the Microsoft Store. This can still create great 3D models and there are plenty of templates you can base your models on.
