Khronos Mission
Software
Silicon
Khronos is an International Industry Consortium of over 100 companies creating royalty-free, open standard APIs to enable software to access hardware acceleration for
3D graphics, Virtual and Augmented Reality, Parallel Computing, Neural Networks and Vision Processing

OpenXR Working Group Members
Design work has started in December 2016 Typically 12-18 months to develop a V1.0 specification

The 3D Portability Problem
Only Apple Only Windows 10
Cross Platform 7
For developers wishing to use the new generation of explicit 3D APIs there is no single API that runs on all desktop and mobile systems!
Problem for native apps that don’t use game engines AND nexgen WebGL!

3D Portability API – Call For Participation
Portability API Spec + Shading Language open source tools
‘WebGL Next’ Design has started inside Khronos
- Could lift ‘Portability API’ to JavaScript and WebAssembly - Provides nexgen graphics and GPU compute for the Web
API Overlap Analysis
‘Portability API’ Specification
A Portability Solution needs to address APIs and shading languages
Open source compilers/translators for shading and intermediate
languages
MIR
DX IL
GLSL
MSL
HLSL
