Projecting Radiolarian Three-dimensional Graphics onto Planetariums: the “Radiolariarium” Project

Abstract

For science communication purposes, we projected three-dimensional (3D) models of radiolarians, obtained through X-ray micro-CT for scientific research, onto a planetarium dome. The represented models possessed a high 3D feeling that enabled easy recognition of radiolarian morphology. Radiolaria have a high affinity with fulldome projection owing to their scale, form, and historical background. We organized a project to promote radiolaria projection as planetarium content in more planetariums. This project would promote the use of planetariums as a visualization and expression medium for 3D data produced in scientific research.
