Interactive lighting in the pearl: considerations and implementation
نویسندگان
چکیده
The Pearl is a multi-modal computer interface initially conceived as an interactive prop for a multi-artistic theatrical performance. It is a spherical hand-held wireless controller embedded with various sensor technologies and interactive lighting. The lighting was a key conceptual component in the instrument’s creation both as a theatrical prop and also as an interface for musical performance as it helps to address conceptual challenges and opportunities posed by the instrument’s spherical form. This paper begins by providing a brief description of the Pearl and its use as a spherical instrument. We then discuss mapping the Pearl both to generate sound and control its interactive lighting, and identify di↵erent strategies for its use. Strategies we identify include feedback regarding performer gesture, information about the state of the instrument, and use as an aesthetic performance component.

This paper proposes an interactive rendering method of cloth fabrics under environment lighting. The outgoing radiance from cloth fabrics in the microcylinder model is calculated by integrating the product of the distant environment lighting, the visibility function, the weighting function that includes shadowing/masking effects of threads, and the light scattering function of threads. The radi...
