Universal rendering with SwiftShader, now open source
středa 29. června 2016
SwiftShader is a software library for high-performance graphics rendering on the CPU. Google already uses this library in multiple products, including Chrome, Android development tools, and cloud services. Starting today, SwiftShader is fully open source, expanding its pool of potential applications.
Since 2009, Chrome has used SwiftShader to enable 3D rendering on systems that can’t fully support hardware-accelerated rendering. While 3D content like
WebGL
is written for a GPU, some users’ devices don’t have graphics hardware capable of executing this content. Others may have drivers with serious bugs which can make 3D rendering unreliable, or even impossible. Chrome uses SwiftShader on these systems in order to ensure 3D web content is available to all users.
Chrome running without SwiftShader on a machine with an inadequate GPU (left) cannot run the WebGL Globe experiment. The same machine with SwiftShader enabled (right) is able to fully render the content.
SwiftShader implements the same OpenGL ES graphics
API
used by Chrome and Android. Making SwiftShader open source will enable other browser vendors to support 3D content universally and move the web platform forward as a whole. In particular, unconditional WebGL support allows web developers to create more engaging content, such as casual games, educational apps, collaborative content creation software, product showcases, virtual tours, and
more
. SwiftShader also has applications in the cloud, enabling rendering on GPU-less systems.
To provide users with the best performance, SwiftShader uses several techniques to efficiently perform graphics calculations on the CPU. Dynamic code generation enables
tailoring
the code towards the tasks at hand at run-time, as opposed to the more common compile-time optimization. This complex approach is simplified through the use of
Reactor
, a custom C++ embedded language with an intuitive imperative syntax. SwiftShader also uses vector operations in
SIMT
fashion, together with multi-threading technology, to increase parallelism across the CPU’s available cores and vector units. This enables real-time rendering for uses such as

Developers can access the SwiftShader source code from its
git repository
