Transversal media move. They move with ease across a variety of interfaces, communities of practice, and applications. With highly compatible file formats, they move across a multitude of 3D-friendly devices, like virtual reality, holograms, and augmented reality projections, and now with the 3D printer, can enter the physical world, more often than not, as plastic. Transversal technologies, like 3D scanning and computer-aided design (CAD), grant an unprecedented control and access, in both magnitude and kind, to the spatial, material, and physical world. Because of this, media illustrate the biopolitical complexity and nuance of the term capture—long used in media praxis—whose meaning can imply both a desire to do justice to a subject, often by means of representational accuracy, and also a desire to do violence to by means of seizing, possessing, or trapping. In turn, this project explores the many affective, epistemological, and aesthetic contours of meaning and impact when transversal media are read through the lens of capture. Organized by five major keywords—making, transversal, play, capture, and preservation—this project illustrates the far-reaching impact of this particular media type that does particular things in this particular moment. Specifically, this project coins the term, transversal media, to discuss this unique media ontology and concretize it through hands-on creative practice and the work of artists, designers, scholars, and activists by centering the methodological richness of hands-on making, creativity, and play. It also addresses the connections between technical affordance and theory, culture, and ethics, as media scholars have modeled with other emerging media formats of the past, like McLuhan on television, Deleuze on film, and Sontag on photography. This approach reveals how various interface affordances and applied practices converse with, and with varying implications, the people, places, and things they mediate. Overall, this project addresses how cultural ideologies are reflected in the design, practice, and rhetoric of 3D transversal media, and how this media genre pushes notions of materiality, embodiment, and power into new realms of thinking, doing, and being.
