Michael Holroyd researches new ways of creating digital models from real-world objects that exhibit complex shape and appearance. He also researches representations that enable efficient editing and analysis of these models, and fabricates objects with realistic designed or measured surface appearance.
Arqball Spin is a 360° photography solution that works right from your phone or tablet. Simply place your object on a turntable and use the free iOS or Android app to capture, edit, and share an interactive 360° spin.

Arqball Spin is my current focus. We came up with the idea after working on the UVaM project and realizing that 360 photography could be brought to the masses using mobile technology.
For my Computer Science Ph.D. I developed an extremely accurate system for measuring the shape and appearance of objects using computer controller cameras and lights. This allows recreating the appearance of that object under any lighting conditions and from any camera direction with photorealistic accuracy.
Interactive 3D visualizations of pottery and sculpture from the Ancient Mediterranean, Asia, Africa, and Ancient Americas. Each object in this catalog can be rotated and enlarged using simple touch gestures. A detailed description written by UVaM curators accompanies each piece and chronicles its history and cultural context.

Created a method for automatically converting a digital 3D model into a multilayer model: a parallel stack of high-resolution 2D images embedded within a semi-transparent medium. Multilayer models can be produced quickly and cheaply and provide a strong sense of an object's 3D shape and texture over a wide range of viewing directions.
Bokeh is a new kind of book about cameras designed for the iPad that contains lessons on focus, depth of field, exposure, and zoom. Each lesson simulates the photographic process on a real scene as you interactively adjust a camera setting.

Research on using modulated lightsources for scanning translucent objects. Discovered equations explaining the effect of translucency and modulated lightsources on optical triangulation methods for measuring the shape of translucent objects.
Research into the synchronization of discrete complex systems. This topic is critical in applications such as communication and transportation networks, neuron respiratory systems, and other systems in which either congestion can occur at individual nodes, or system wide synchrony is of importance to proper functionality.
