The poster was presented at the SIGGRAPH '16 Special Interest Group on Computer Graphics and Interactive Techniques Conference, Anaheim, CA — July 24 - 28, 2016. We describe a digital design process that interfaces real-time data with 3D modelling and 3D printing techniques. Digital Impressionism is a platform for exploring new material possibilities, by 3D modelling physical and digital objects, affected by the invisible forces that act upon them, using a 3D pointcloud as a medium. We describe an experimental project run with our MA and PhD students, incorporating real-time audio data to manipulate 3D physical hybrid forms.
