An Inexpensive Light Stage Dome

This article describes a process for constructing a real-world 1 m-diameter icosahedral dome frame with equipment mounting points at the vertices. Such frames, called Light Stage domes, are important tools for computer graphics and vision measurements and relighting applications. Typical domes have 2 m diameter and are constructed from bolted steel parts. The new half-size dome is inexpensive, portable, and can be quickly constructed with simple hand tools. This makes Light Stage experiments practical for preliminary exploration, application to on-site artifacts, and student research.
