Possible Bodies questions and problematises the formulation, conception, and rendering of bodies across different 3D technologies such as modelling, tracking and scanning. Their affirmative critical research draws attention to the ways in which these techniques end up implementing and even amplifying a host of prejudices based on race, gender, class, age and ability which, far from being circumstantial, are woven into the actual source code of all sorts of applications. We talk to Femke Snelting about embodiments, optimisation, and 3D disasters, about the possible and the probable, parametric interfaces, and open standards, and about disobedient action research.
