Screenshots taken with HoloLens are often difficult to comprehend, as they only show the scene as seen by the user, but not the user itself. How is he interacting with the scene, where is he standing in relation to the view?
Therefore, photos of HoloLens apps usually show a 3rd person view. Getting a real live transmission of the 3D objects seen by a HoloLens user works with the new Spectator View by Microsoft. However, setting that up is tricky: you need 2 HoloLenses, some special hardware and in the ideal case a 3D printed mount.
A simpler approach for a still screen is to take a photo with a good quality camera, and then to render the scene with matching perspective.
Unity itself is not directly suited to rendering a scene to an image, and it also lacks some of the advanced tools to align the 3D scene with a photo.
Here, I’ll describe an approach to use 3ds Max to simulate the view of a HoloLens user in 3rd person view. I used this for our PalKranHoloPlan AR8000 project, which we created during the Palfinger Hackathon. Continue reading “How to create Photos of HoloLens in Use”
