In a similar fashion to device previews, 3D Transforms can be used to create prototypes within multi-dimensional space for testing and designing for augmented or virtual reality applications.
Take for instance a heads up display, or infotainment system in a vehicle. The experience and interface elements can be designed in two dimensional space, and then can be transformed into three-dimensional space and shown in the context of a vehicle dashboard, making it possible to create more compelling prototypes and interactions.
To do this, set up your first artboard with the objects transformed into 3D space. Copy the artboard, and adjust the elements to create the next stage of the interaction. Prototype triggers and actions work the same in three dimensions as they do in two dimensions. Connect your design together using taps, drags or voice, and use Auto-Animate to bring it all together.
