Microsoft 3D Viewer
3D Viewer is a 3D computer graphics viewer and augmented reality application that was first included in Windows 10 1703. It supports multiple file formats, including the .fbx, .3mf, .obj, and .stl.
History
On the first launch, 3D Viewer automatically loads a "Bee.glb" file and renders an animated wasp on a grey background. Users can change the viewing angle, select and watch one of the available animations or adjust either of the 3 light sources. The light setup can be saved as "themes" and applied to other 3D objects quickly. The app also features four "Quick Animations".These are ways in which the app can showcase the 3D object by changing the viewing angle. For example, the "Turntable" item rotates the viewpoint around the object latitudinally. If the device running the app is equipped with a camera, the app can create a mixed reality experience that will allow you to tap on a surface you are viewing, and the 3D model will drop onto that surface. It will then make a rudimentary attempt at SLAM in order to keep the object in place.
