Art of the Alhambra

Comares Hall is the most majestic room in the Alhambra. It is located within Comares Tower, which was built by artisans from the nearby town of Comares. The Hall measures 30’x30’, with a 60-foot-high domed ceiling and nine large windows. The ceiling, beams, and doors of Comares Hall are of carved wood, the floors and wainscoting are glazed earthenware mosaic, and other ornamental surfaces are o...

Alhambra: A System for Producing 2D Animation

There is a great interest in producing computer animation that looks like 2D classic animation. The flat shading, silhouettes and inside contour lines are all visual characteristics that, joined to flexible expressiveness, constitute the basic elements of 2D animation. We have developed methods for obtaining the silhouettes and interior curves from polygonal models. Virtual lights is a new meth...

Finding Stellar Streams in Photometric Surveys

The advent of high-quality, wide-area photometric databases has enabled significant advances in our knowledge of the structure, constituents, and accretion history of our Galaxy. Matched-filtering techniques allow us to map the spatial distributions of stellar populations with particular color-magnitude characteristics. This has already led to the detection of several long tidal streams in the ...
