3. WebGL’s Origin Story 2011-Today
23.8%
31.7%
13.9%
30.6%
Google data – July 2018
2011-Today
Browsers have access to a pervasive native API for the first time. Can build a JavaScript stack for 3D that can be accelerated everywhere
2003-Today
Pervasive on Windows, Mac and Linux
Desktops and Workstations
AND Android and iPhone Mobile Phones
OpenGL ES is the most prevalent 3D API in history - Billions of devices!
1992-Today
Pervasive on Windows, Mac and Linux
Desktops and Workstations

4. WebGL Stack Content JavaScript, HTML, CSS, ...
Content downloaded from the Web
Low-level WebGL API provides a powerful foundation for a rich JavaScript middleware ecosystem
JavaScript Middleware
Middleware provides accessibility for non-expert programmers
E.g. three.js library
CSS
Reliable WebGL relies on work by both GPU and Browser Vendors
->
Khronos has the right membership to enable that cooperation
Browser provides WebGL
3D engine alongside other HTML5 technologies - no plug-in required
JavaScript
HTML5
OS Provided Drivers WebGL uses native OpenGL or OpenGL ES or Angle = OpenGL ES over DX9/11

5. WebGL’s Evolution After WebGL 2.0? 2007 OpenGL ES 2.0
W3C is working on WebGPU
Layering over Vulkan/DX12/Metal
Possibly leveraging SPIR-V IR
Pervasive OpenGL ES 2.0
OpenGL and OpenGL ES ships on every desktop and mobile OS.
3D on the Web is enabled!
Desktop Graphics
Textures: NPOT, 3D, Depth, Arrays, Int/float
Objects: Query, Sync, Samplers
Seamless Cubemaps, Integer vertex attributes
Multiple Render Targets, Instanced rendering
Transform feedback, Uniform blocks
Vertex array objects, GLSL ES 3.0 shaders
Apple does not ship OpenGL ES 3.1
Cannot bring compute shaders into core WebGL
Mobile Graphics Programmable Vertex and Fragment shaders
Compute Shaders
2007 OpenGL ES 2.0
2012 OpenGL ES 3.0
2014 OpenGL ES 3.1
Work in Progress
Compute Context
Multiview extension
4 years
5 years
2011
WebGL 1.0
2017
WebGL 2.0
Conformance Testing is vital for Cross-Platform Reliability
WebGL 2.0 conformance tests are very thorough 10x more tests than WebGL 1.0 tests

6. WebGL Deployment – WebGL 2.0 is Here!
93.26% Globally
Pervasive, portable access to OpenGL ES 2.0-class mobile graphics
WebGL 1.0
OpenGL ES 3.0-based desktop-class graphics comes to the Web!
WebGL 2.0
65.77% Globally
WebGL 2.0 will reach WebGL 1.0 levels of availability when Safari and Edge ship enabling a new class of Web-based AR/VR 3D Apps!

7. The Metaverse will be the Web!

8. Bringing VR and AR to the Web
Native XR Apps
Web XR Apps
Future versions of OpenXR will include cross-platform extended AR functionality
WebXR
3D Engines
3D Engines
System-exposed AR Capabilities
Close ongoing collaboration between WebXR and OpenXR
Khronos providing the foundation for 3D and XR in the Web and native stacks
