This has not changed what SketchUp Viewer is for, but rather added to it. SketchUp can still be used for the regular view model of a 3D scene from within Windows, and the obvious benefit here is that you can still easily move objects around the scene as needed. However, there is another powerful feature here as well - if you use Windows as your SketchUp Viewer, then it creates a presence in your virtual environment that is distinct from your regular desktop or laptop viewer. This allows you to create a presence on a particular device so that your users can not only see you, but also know that they can interact with you too. So, with this new, mixed reality feature of SketchUp Viewer, the user not only has the ability to interact with your physical work but is also able to physically interact with your virtual work.
With the Mixed Reality mode of this application, you get the best of both worlds. It allows people not only to explore and interact with a physical model, but also the ability to see the world from their perspective along with their own. This is a big step forward in how digital solutions and services are moving forward in bringing true mixed reality to the mainstream, and we look forward to seeing more of these solutions in the future.
