- Doom3 / Quake 4 / Prey, Pacific Fighters, Serious Sam, World of Warcraft (on Apple)

• MCAD- Dassault CATIA, PTC Pro/Engineer

• DCC- Autodesk Maya, Softimage XSI

• Imaging - Medical – GE / Philips / Siemens- Oil and Gas – Landmark / Paradigm

• Scientific Visualization- Many university and research applications

• High-end Video Editing- Adobe After Effects, Discreet Fire / Smoke

OpenGL has been the leading cross platform graphics API for over 10 yearsThe OpenGL Architecture Review Board (ARB) voted to become part of Khronos

in July 2006


�� • OpenGL and OpenGL ES are now evolving under one IP framework

- Design innovations can be freely shared between the APIs

• OpenGL and OpenGL ES can share same resources and outreach- Common Conformance tests, marketing and web-site, tool chains etc.

• OpenGL and OpenGL ES Working Groups will remain independent- Both groups will be able to make decisions that best serve their own markets

Desktop Markets

Architectural design expertise

Market feedback on streamlining functionality

Momentum - hundreds of millions of OpenGL ES devices


!��"��!��"��• OpenGL ES has leveraged desktop OpenGL architecture

- OpenGL ES 1.1 streamlined OpenGL 1.5- OpenGL ES 2.0 streamlined OpenGL 2.0 and the GLSL shading language

• Next Generation OpenGL “Mount Evans” will leverage OpenGL ES 2.0- Adding significant new functionality to the streamlined OpenGL ES 2.0 core

• OpenGL ES will benefit from the architectural innovation of “Mount Evans”- Nexgen OpenGL ES – “Halti” will use desktop innovations for performance and functionality

July 2006 - OpenGL 2.1 Released and OpenGL ARB Joins Khronos

OpenGL SDK and Quarterly Newsletter Released

“Longs Peak”Target Release Date

4Q06 1Q07 2Q07 3Q073Q06 4Q07

“Mount Evans”Target Release Date

OpenGL 2.1 - Programmability Enhancements- Backwards compatible with all previous versions of OpenGL - Pixel Buffer Objects for fast copies to/from framebuffer

- sRGB color space textures for color management flexibility- Increased flexibility of shader programming:

Non-square matrix support, arrays as first-class objects etc.

Mount Evans – New Generation Functionality- Builds on Longs Peak

- Geometry shader- Stream out of vertex data to a buffer object

- Texture arrays and buffer objects

Longs Peak – API Rationalization- Easy migration path from OpenGL 2.0

- Introduces new object model- Higher performance

- Easier coding- Easier to implement


��"��"�� #$� ��%��&�%��#$� ��%��&�%• ARB-developed resources

- API documentation and formal specifications

• Community-developed resources selected by the ARB- Libraries, Tutorials, Tools- gDEBugger - ARB is subsidizing Graphic Remedy for OpenGL developers in academia

• Developer documentation (“man pages”)- Completely up to date with OpenGL 2.1- In Docbook XML format, easy to retarget to many different delivery formats

• OpenGL Pipeline Newsletter- Quarterly, includes status reports and mini-tutorials

• OpenGL.org Message Boards- ARB members and many other smart developers participate

'��##�(�)�*��#�� '��##�(�)�*��#�� • COLLADA is a XML database schema for 3D assets

- Can hold geometry, animation, visual effects, physics – everything to do with a scene

• COLLADA transports 3D assets between applications- Enables binding of diverse DCC and 3D processing tools into a production pipeline

• COLLADA can be lossless – never lose information- Retains all information - even multiple versions of the same asset

• COLLADA is an open, archive-grade format that retains meta information- When your DCC tool upgrades, you keep your assets

Tool 1

Tool 2

Tool 3

Tool 4

COLLADA is non-destructive and so supports round-

tripping of tools to enable powerful authoring pipelines


'��##�'�� '��##�'��

• Conditioning pipelines take authored assets and:

• 1. Strips out authoring-only information

• 2. Re-sizes to suit the target platform• 3. Compresses and formats binary

data for the target platform

• Different target platforms can use the same asset database with the appropriate conditioning pipeline

Multiple tools create assets and scenes in a COLLADA

• COLLADA is an interchange format - not a delivery format or a scene graph


'��##��'��##��• COLLADA 1.4 supported by all major tools and thousands of users

- 3ds Max, Adobe Photoshop CS3, Blender, DAZ|Studio, Feeling Viewer, - NVIDIA FX Composer, Google Earth, Houdini, Maya, Sketchup, and XSI

• Google Earth v4 imports COLLADA - KML v2.1 imports COLLADA models such as buildings, monuments, and statues- Full support for textures and level of detailing

• Unreal Engine 3 using COLLADA- To enable assets to be imported from any authoring tool

• Adobe Photoshop CS3 imports COLLADA- For texture editing on 3D objects


'��##�� '��##�� &��&��++��,�-��,�-�

• Adding support for OpenGL ES 2.0 shaders- Enhanced shader authoring

• Richer asset types- Integration of audio, video and vector graphics assets

OpenGL ES 2.0 supported

Conformance Tests Released


��• Shader effects are a new paradigm

- Consist of textures, shaders, geometry passes and control

• DCC tools author shaders using COLLADA FX file format- Built on CgFX – contributed by NVIDIA

• Now need ways to use effects in applications at runtime- Enable effects to be portably deployed on many different devices

Authoring

Deployment

��

Streamline the deployment of shader-rich content by defining file formats and

APIs to enable shaders to be portably deployed and

accelerated


Application

OpenGL 2.0 / OpenGL ES 2.0

glFX Runtime API

��) �� ) ��

- Existing Khronos standards- New glFX standard - Application specific code/data

Application traverses scene data, uses the glFX Runtime API to extract effects information to setup the rendering pipeline

COLLADA FX EffectsTextures, shaders programs, geometry, control and pass information

COLLADAFile format for 3D asset interchange – widely adopted by DCC tools vendors and Google, Adobe, Epic etc.

OptionalConditioning for DeliveryOptionally create data

representations for delivery to target devices

.�*��/��0.�*��/��0• It doesn’t!• Khronos is purely a non-profit organization

- Funded by member dues – to cover costs

• Our members make money by selling PRODUCTS enabled by standards- NOT trying to charge for the standard itself

$

Selling an API would generate relatively small

amounts of revenue

An open, royalty free API standard creates much

larger market opportunities

Our members cooperate to create standards –and compete in the marketplace with products

that use Khronos standards
