Скачать или смотреть Physics Based VR Dial with the XR Interaction Toolkit

This video is an exercise in creating a physics based dial in VR using the XR Interaction Toolkit and Joint components. We discuss how to store a rotation value, how to set limits on the dial, how to edit the starting value and position, and how to how to convert the degree rotation into a new range of values.
