• "2-1/2D" Portrait Creation

  Prof. Douglas C. Acheson
  Computer Graphics Technology
  Purdue School of Engineering and Technology at Indianapolis
  
  This tutorial will give participants the opportunity to utilize the 3D NURBS modeling program Rhinoceros (Rhino) to create unique, stylized portraits without the need for complex surface modeling knowledge. Digital pictures of the participants will be used as background images within Rhino to extract unique facial characteristics in the form of closed splines. Extruded and altered in elevation, the facial features will be accentuated by textures, lighting and camera angles. Initial acquisition of the background images will also be discussed as well as the use of Photoshop to produce high-contrast images for tracing. This tutorial will illustrate how 3D modeling programs can be used as an artist's tool to inspire creative expression beyond that of traditional engineering applications.This workshop will be taught at the introductory level. No prior knowledge of Rhino or Photoshop is required.

• Object Oriented Multimedia Representation

  Dr. Dmitry Vatolin, Alexander Zhirkov
  Graphics and Media Lab, CMC, Moscow State University, Moscow, Russia
  
  Participants of this tutorial will be instructed in the theoretical foundations and practical methods of modern media data representation. For video data object oriented approach (OOA) actively used in last extensions of MPEG-4 video format and in applications of H.264. OOA will be discussed in the following areas: videoconferencing, multi-layered and other 3D video representations, modern image compression formats, model-based audio coding, including so-called hybrid coder and MPEG-4 structural audio format. Summarizing comparison between OOA and uniform representations will be performed.
