2002 – LED Cubes

While volumetric displays have a long history dating back from the 1910s and are still an active topic of research, the improvement and democratization of LED technology made it possible for anyone to build low-resolution volumetric displays by arranging many LEDs in a 3D matrix. Today, hundreds of video tutorials and demos of LED cubes can be found on YouTube (the left image is from a 2021 tutorial). Perhaps one of the earliest people to come up with the idea was artist Todd Holoubek, who […]

2019 – Physicalizing Cardiac Blood Flow Data

Blood flow data from cardiac 4D Flow MRI (magnetic resonance imaging) holds much potential for research and diagnosis of flow-related diseases. However, understanding this data is quite challenging – after all, it is a volumetric vector field that changes over time. This paper proposes a novel slice-based physical model as a complementary method for visualizing the flow data. The design of this model respects the conventional method of viewing medical imagery (i.e., in cross-sections) but has […]
