Abstruse

Complex 3D curves tin can exist created by directly drawing mid-air in immersive environments (Augmented and Virtual Realities). Cartoon mid-air strokes precisely on the surface of a 3D virtual object, nevertheless, is difficult, necessitating a projection of the mid-air stroke onto the user "intended" surface curve. Nosotros nowadays the first detailed investigation of the cardinal problem of 3D stroke projection in VR. An assessment of the design requirements of real-fourth dimension drawing of curves on 3D objects in VR is followed by the definition and nomenclature of multiple techniques for 3D stroke project. We analyze the advantages and shortcomings of these approaches both theoretically and via practical pilot testing. We so formally evaluate the two most promising techniques spraycan and mimicry with xx users in VR. The report shows a strong qualitative and quantitative user preference for our novel stroke mimicry projection algorithm. Nosotros farther illustrate the effectiveness and

utility of stroke mimicry to describe complex 3D curves on surfaces for various creative and functional design applications.
