摘要
INSTRUMENT | One Antarctic Night (IOAN) is a performative, multiparticipant reconfigurable artwork that engages open astronomical data in combination with data generated by robotic telescopes in Antarctica. IOAN places visitors inside a virtual star field of over 800,000 astronomical objects that form part of the Large Magellanic Cloud. This star field, created from observations in Antarctica and fused with additional data from multiple open astronomical repositories, is situated waist high within the virtual environment and stretches out beyond participants in all directions. Multiple participants can walk about the environment and collaboratively explore the star field by taking hold of the "fabric" of space, creating ripples and waves, and interacting with individual or sets of objects to create visual and auditory data remixes. The interaction places the astronomical data within a virtual reality visual and sonic remix engine that is a fundamental component of the artwork and is used to construct the virtual world. All graphics and spatialized ambisonic audio are procedurally generated from the data via real-time database queries. Our work incorporates machine learning approaches combined with granular and concatenative synthesis for generating the environment's unique soundscape. INSTRUMENT | One Antarctic Night evolved from our ongoing work in developing aesthetic data remixing and immersive data-driven experiences. Dataremix proposes the creation of the "datamade," a concept analogous to Duchamp's "readymade." IOAN is a meta-datamade in that it is a virtual instrument within which participants collaboratively create datamades through visual and auditory aesthetically driven remixes of astronomical data.
