This chapter shifts the focus from the sketching system and the interaction techniques to existing projects in various application domains. It presents the created artifacts and use-cases to provide an overview of how different domains use mid-air 3D sketching. The technology needed to enable 3D sketching has become more accessible due to the availability of consumer VR devices and companies have released software that enables users to sketch and design in 3D such as Tilt Brush, Gravity Sketch, and Quill. Research tools have also been made available for other disciplines to work with such as the Lift-Off and Hyve systems. Traditional sketching is a central part of early conceptual design and allows the user to quickly produce initial ideas. Artists have used various techniques to create the perception of depth in their images but immersive sketching enables new possibilities for 3D art.
