3D Interaction With Multispectral Images

Adoration of the Magi

During Summer 2007 I worked with the Immersive Visualization Lab (IVL) at the California Institute for Telecommunications and Information Technology (Calit2) on a visualization project that gave users the experience of walking through layers of an image set. Harnessing the powerful fully immersive visualization technology available at the IVL - including the StarCAVE - we developed a versatile high resolution image viewer which allowed for interaction with multi-gigabyte size image files in the StarCAVE and on tiled display walls. Image sets can contain multiple layers, with the primary data set I worked with consisting of scans of Renaissance paintings in different spectra of light, which reveal different information about the painting (visible light shows what we see with our eyes, infrared shows the undersketch, ultraviolet shows pigment information, and x-ray shows features of the artistic medium and canvas/wood board). The resulting system allows users to enter a 3D visualization environment in which these multi-layer image sets are controlled and manipulated by their movements.

Imagine moving forward and having 15-foot tall high resolution scans of Da Vinci's "Adoration of the Magi" fading through you as you walk.

This project was a collaboration with Jurgen Schulze and Maurizio Seracini of the IVL at Calit2. A video demonstration of a slightly updated version of the project is shown below:
