Drawing is a common form of communication and a means of artistic expression. Many of us believe that the ability to draw accurate representations of objects is a skill that either comes naturally or is the result of hours ...

We present a general visual analytics architecture that is designed and implemented to effectively analyze unstructured social media data on a large scale. Pipelined on a high-performance cluster configuration, MPI processing, ...

Current graphics processors are very slow for displaying shaded 3D objects. A lot of work is being done in order to define faster display processors by using massive parallelism and VLSI components. Our proposal goes along ...

Most existing volume rendering algorithms assume that data sets are memory-resident and thus ignore the performance overhead of disk I/O. While this assumption may be true for high-performance graphics machines, it does ...

The IBISA (Image-Based Identification/Search for Archaeology) system manages databases of digital images of archaeological objects, e.g. ancient coins, and allows the user to perform searches by examples. IBISA was de- ...

Thanks to an increase in rendering efficiency, indirect illumination has recently begun to be integrated in cinematic lighting design, an application where physical accuracy is less important than careful control of scene ...

Advances in digital technology for the graphic and textual representation of manuscripts have not, until recently, been applied to the world's oldest manuscripts, cuneiform tablets. This is due in large part both to the ...
