  Documentaries


Aside from research and development, the Graphics Lab has had the pleasure of working and releasing shot films with intense graphic elements. These films do not only help show the multiple usues of the technologies discovered withing the lab, but also helps us discover new problems within the film world that can be researched in the future.

The Parthenon

The Parthenon

"The Parthenon" is a short computer animation which visually reunites the Parthenon and its sculptural decorations, separated since the early 1800s. The film used combinations of time-of-flight laser scanning, structured light scanning, photometric stereo, inverse global illumination, photogrammetric modeling, image-based rendering, BRDF measurement, and Monte-Carlo global illumination in order to create the twenty-some shots used in the film.
Relighting Human Locomotion

Relighting Human Locomotion

We present an image-based approach for capturing the appearance of a walking or running person so they can be rendered realistically under variable viewpoint and illumination. In our approach, a person walks on a treadmill at a regular rate as a turntable slowly rotates the person's direction. As this happens, the person is filmed with a vertical array of high-speed cameras under a time-multiplexed lighting basis, acquiring a seven-dimensional dataset of the person under variable time, illumination, and viewing direction in approximately forty seconds. We process this data into a flowed reflectance field using an optical flow algorithm to correspond pixels in neighboring camera views and time samples to each other, and we use image compression to reduce the size of this data. We then use image-based relighting and a hardware-accelerated combination of view morphing and light field rendering to render the subject under user-specified viewpoint and lighting conditions. To composite the person into a scene, we use an alpha channel derived from back lighting and a retroreflective treadmill surface and a visual hull process to render the shadows the person would cast onto the ground. We demonstrate realistic composites of several subjects into real and virtual environments using our technique.
Computer Animation Festival

Computer Animation Festival

The premier annual event for the world's most innovative, accomplished, and amazing digital film and video creators. An internationally recognized jury receives hundreds of submissions and presents the best work of the year in daily Animation Theaters and the Electronic Theater (matinée and evening shows). Selections include outstanding achievements in time-based art, scientific visualization, visual effects, real-time graphics, and narrative shorts.
