Using the surface magnetism technique, you can place a holographic object on a real-world physical surface. By aligning the object's orientation with the real-world surface, you can create a more immersive and natural experience for the user.
Surface magnetism in MRTK (Mixed Reality Toolkit) for Unity
MRTK provides scripts and example scenes for the surface magnetism technique. You can use surface magnetism with various types of inputs such as hand-ray, eye gaze, and motion controllers.
