  1. ARB Update June 2002

  2. Synergize Graphics and Media Processing Synergize Authoring & Deployment “Embedded OpenGL” “Embedded OpenML” Scalable, small footprint2D & 3D graphics Small footprint video & audio processing Creating Open API Standards

  3. OpenML • API set for dynamic media authoring • OpenML 1.0 spec released at Siggraph 2001 • Key task is now to enable and encourage shipping implementations • “Embedded OpenGL” • OpenGL profiles for embedded platforms • Significant Industry interest • Informal working group discussions started Khronos is a Two Track Organization

  4. New Participation Framework • Open Khronos membership for interested companies • Four levels of participation: • Application developers – can use Khronos-based drivers with no license or royalties • Adopters - any company can sign a royalty free license to implement Khronos specifications • Contributors - open membership, nominal annual fee, working group participation & voting • Promoters – founders of the group, driving the Khronos organization and its standards Board of Promoters Specs generated by Working Groups are passed back to the Promoters Board for final ratification WorkingGroup WorkingGroup WorkingGroup WorkingGroup Board of promoters establish working groups for any needed task: spec generation, marketing, reference implementations, conformance tests Open Contributor Membership with Full Working Group Voting Rights

  5. Working Group Update • Where are we now? • Significant industry interest • 100’s of companies have expressed support for Khronos activities • Rich set of companies from which we can form actual working groups (NOT 100’s!) • Bodes well for final adoption • Participation Agreement is close! • BUT we have been waiting a year – cost us some momentum • Struggled to get IP framework in place(!) – but we are there now • OpenML implementation group • The task: ABI definitions, sample implementations, conformance tests etc… • Have been waiting for resources and framework from participation agreement • High energy new participants: DVS, RealViz – other companies waiting • Khronos has budget for contract engineering resource if needed • “Embedded OpenGL” working group • Significant outreach success • Waiting for participation agreement • Ad hoc working group meetings already started to refine 3Dlabs’ strawman

  6. Eliminate redundancy Duplicated functionalityUnnecessary queriesData-type variants Eliminate workstation functionality e.g. 3D textures Difficult/costly to implement with little benefit in embedded space Proposed Hardware Profiles • Addressing broad application requirements • Core 2D • High-quality 2D geometry • Lines, polygons and text • Core Image • High quality affine transforms • Core 3D • Minimum footprint 3D • Including texture-mapping Core 3D Core 2D Core Image

  7. Core2D Prototype Implementations

  8. Safety Critical Line-poweredAppliances Consoles Avionics STBs Strong support from ARINC and aerospace companies including Boeing, Airbus, Rockwell, Honeywell, Smiths, Lockheed… Internet Terminals Poorly defined standard API requirements.Discussions with BroadcastCL group- to avoid divergence Automotive At a meeting in April 2002, Symbian and the cell phone industry selected Khronos’ “Embedded OpenGL” as the graphics API for cell phones with accelerated 3D in 2004 Phones PDAs Web pads Cameras Hand-heldAppliances Industry Momentum New Visual Processing APIs

  9. Aggressive Timelines • Embedded industry won’t wait • Need ratifiable specs by the end of the year • Next working group meeting at Siggraph 1Q03 “Embedded OpenGL 1.0” ratified by Khronos 4Q02 First draftspecification July First working Group Meetings June Khronos Participation agreement available

  10. Embedded OpenGL Roadmap • For embedded OpenGL applications • Embedded OpenGL can eventually migrate to “pure” OpenGL 2.0 • Provides a small core for advanced embedded visual processing • Can repeat the exercise of eliminating non-embedded functionality • OpenGL 2.0 already being designed with this transition in mind Future Streamlined API Standards “Pure” OpenGL 2.0 OpenGL 2.0 EmbeddedOpenGL 2.0 OpenGL 1.3 Eliminate redundant functionality. Gain access to programmability. EmbeddedOpenGL 1.0 Eliminate redundant functionality. Profiles to suit market segments.
