3
Recently Published Standards

• 1. ISO/IEC 14778, Presentation Environment for
  Multimedia Objects (PREMO).
• 2. ISO/IEC 14772-1, Virtual Reality Modeling
  Language (VRML)
• 3. ISO/IEC 12087-5, Basic Image Interchange
  Format (BIIF)

4
Current work in JTC 1/SC 24

• New part (EAI) and an Amendment to VRML
• Portable Network Graphics (PNG)
• Revised Procedures for Registration of Graphical
  Items - Profiles of Standards
• Environmental Representation
• (SEDRIS - 4 projects, 2 NWIP)
• GeoVRML, part of the Web3D Consortium
• SC 24 products relevant to spatial standards
  (CGM, PNG, BIIF, VRML)

5
Future work

• SEDRIS Data Coding Specification and Spatial
  Reference Model (2 projects)
• Cooperative work with Web3D Consortium, VRML and
  GeoVRML(18 projects)
• Cooperative work with ISO TC211,Open GIS
  Consortium, SISO, DGIWG FACC Working Party
• Digital document archival and distribution

6
SC 24s Extent and Experience

• Application Program Interfaces (APIs)
• Data Transfer Standards (both real-time and
  non-real time)
• Conformance, testing and certification
• Coded representations (but we rely on SC 29 for
  most compressed formats)
• Supporting work such as reference models and
  formal description techniques
• Development of object-oriented standards
• Standards to support requirements for
• distributed implementations
• real-time embedded systems
• high performance and parallel processing
• high accuracy

Aspects of Spatial Information in Graphics and
Imaging

• Computer graphics and imaging includes modeling
  the real world in 3D
• Digital images have traditionally been produced
  in 2D for distribution, display and interaction,
  but 3D rendering is of growing importance
• There is also a long history of 3D graphical
  interaction, 3D rendering of images and sound,
  etc.
• Today we have a significant opportunity to
  achieve better integration of true spatial
  information with graphics and images

Some Key Markets for SC 24 Standards

• E-Commerce and e-business using the web
• presentation and interaction, including with
  legacy systems
• distribution of products as graphics
• Entertainment and games
• distributed and multi-party real time 3D
• market for 3D places and things
• Graphics intensive applications
• Modeling and Simulation (MS)

Objectives and Goals

• Take advantage of the potentials for exchange
• Build on the relationships already established
• Ensure that the time invested has positive
  results to all participating entities
