3 .WebGL’s Origin Story 23.8% 31.7% 13.9% 30.6% Google data – July 2018 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 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
4 .Content JavaScript, HTML, CSS, ... WebGL Stack JavaScript Middleware CSS JavaScript HTML5 Browser provides WebGL 3D engine a longside other HTML5 technologies - no plug-in required OS Provided Drivers WebGL uses native OpenGL or OpenGL ES or Angle = OpenGL ES over DX9/11 Content downloaded from the Web Middleware provides accessibility for non-expert programmers E.g. three.js library Low-level WebGL API provides a powerful foundation for a rich JavaScript middleware ecosystem Reliable WebGL relies on work by both GPU and Browser Vendors -> Khronos has the right membership to enable that cooperation
5 .2007 OpenGL ES 2.0 2012 OpenGL ES 3.0 Desktop Graphics Textures: NPOT, 3D, D epth, 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 Mobile Graphics Programmable Vertex and F ragment shaders 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 Pervasive OpenGL ES 2.0 OpenGL and OpenGL ES ships on every desktop and mobile OS. 3D on the Web is enabled! WebGL’s Evolution 2014 OpenGL ES 3.1 4 years 5 years Compute Shaders Work in Progress Compute Context Multiview extension Apple does not ship OpenGL ES 3.1 Cannot bring compute shaders into core WebGL After WebGL 2.0? W3C is working on WebGPU Layering over Vulkan/DX12/Metal Possibly leveraging SPIR-V IR https://www.w3.org/community/gpu/
6 .WebGL Deployment – WebGL 2.0 is Here! http://caniuse.com/#feat=webgl 93.26% Globally 65.77% Globally WebGL 1.0 WebGL 2.0 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! P ervasive, portable access to OpenGL ES 2.0-class mobile graphics OpenGL ES 3.0-based desktop-class graphics comes to the Web!
7 .The Metaverse will be the Web! https://xkcd.com/1367/
8 .Bringing VR and AR to the Web Web XR Apps WebXR Native XR Apps System-exposed AR Capabilities 3D Engines 3D Engines Close ongoing collaboration between WebXR and OpenXR Khronos providing the foundation for 3D and XR in the Web and native stacks Future versions of OpenXR will include cross-platform extended AR functionality
