<< We're happy to announce a new open source project called Almost Native Graphics Layer Engine, or ANGLE for short. The goal of ANGLE is to layer WebGL's subset of the OpenGL ES 2.0 API over DirectX 9.0c API calls. We're open-sourcing ANGLE under the BSD license as an early work-in-progress, but when complete, it will enable browsers like Google Chrome to run WebGL content on Windows computers without having to rely on OpenGL drivers. >>
