5Introduction
6------------
7
8SwiftShader is a high-performance CPU-based implementation of the OpenGL ES and Direct3D 9 graphics APIs<sup>1</sup><sup>2</sup>. Its goal is to provide hardware independence for advanced 3D graphics.
9
10Building
11--------
12
13SwiftShader libraries can be built for Windows, Linux, and Mac OS X.
14Android and Chrome (OS) build environments are also supported.
15
16* **Visual Studio**
17
18 On Windows, open the [SwiftShader.sln](SwiftShader.sln) file using [Visual Studio Community](https://visualstudio.microsoft.com/vs/community/) or compatible version, and build the solution. Output DLLs will be placed in the _out_ subfolder. Sample executables such as _OGLES3ColourGrading_ can be found under the Tests solution folder and can be run from the IDE.
19
20* **CMake**
21
22 [Install CMake](https://cmake.org/download/) for Linux, Mac OS X, or Windows and use either [the IDE](https://cmake.org/runningcmake/) or run the following terminal commands:
23
24 mkdir build && cd build
25 cmake ..
26 make --jobs=8
27
28 ./unittests
29 ./OGLES2HelloAPI
30
31Usage
32-----
33
34The SwiftShader libraries act as drop-in replacements for graphics drivers.
35
36On Windows, most applications can be made to use SwiftShader's DLLs by placing them in the same folder as the executable. On Linux, the LD\_LIBRARY\_PATH environment variable or -rpath linker option can be used to direct applications to search for shared libraries in the indicated directory first.
37
38Contributing
39------------

41See [CONTRIBUTING.txt](CONTRIBUTING.txt) for important contributing requirements.
42
43The canonical repository for SwiftShader is hosted at:
44https://swiftshader.googlesource.com/SwiftShader
45
46All changes must be reviewed and approved in the [Gerrit](https://www.gerritcodereview.com/) review tool at:
47https://swiftshader-review.googlesource.com
48
49Authenticate your account here:

51
52All changes require a [Change-ID](https://gerrit-review.googlesource.com/Documentation/user-changeid.html) tag in the commit message. A commit hook may be used to add this tag automatically, and can be found at:
53https://gerrit-review.googlesource.com/tools/hooks/commit-msg. To clone the repository and install the commit hook in one go:
54
55 git clone https://swiftshader.googlesource.com/SwiftShader && (cd SwiftShader && curl -Lo `git rev-parse --git-dir`/hooks/commit-msg https://gerrit-review.googlesource.com/tools/hooks/commit-msg ; chmod +x `git rev-parse --git-dir`/hooks/commit-msg)
56
57Changes are uploaded to Gerrit by executing:
58
59 git push origin HEAD:refs/for/master
60
61Testing
62-------
63
64SwiftShader's OpenGL ES implementation can be tested using the [dEQP](https://source.android.com/devices/graphics/testing) test suite.
65
66See [docs/dEQP.md](docs/dEQP.md) for details.
67
68Third-Party Dependencies
69------------------------
70
71The [third_party](third_party/) directory contains projects which originated outside of SwiftShader:
72
73[LLVM](third_party/LLVM/) contains an outdated and diverged copy of the [LLVM](http://llvm.org/) compiler framework. Until further notice, maintenance fixes can be made directly in the SwiftShader repository.
74
75[subzero](third_party/subzero/) contains a fork of the [Subzero](https://chromium.googlesource.com/native_client/pnacl-subzero/) project. It is part of Google Chrome's (Portable) [Native Client](https://developer.chrome.com/native-client) project. Its authoritative source is at [https://chromium.googlesource.com/native_client/pnacl-subzero/](https://chromium.googlesource.com/native_client/pnacl-subzero/). The fork was made using [git-subtree](https://github.com/git/git/blob/master/contrib/subtree/git-subtree.txt) to include all of Subzero's history, and until further notice it should **not** diverge from the upstream project. Contributions must be tested using the [README](third_party/subzero/docs/README.rst) instructions, reviewed at [https://chromium-review.googlesource.com](https://chromium-review.googlesource.com/q/project:native_client%252Fpnacl-subzero), and then pulled into the SwiftShader repository.
76
77[llvm-subzero](third_party/llvm-subzero/) contains a minimized set of LLVM dependencies of the Subzero project.
78
79[PowerVR_SDK](third_party/PowerVR_SDK/) contains a subset of the [PowerVR Graphics Native SDK](https://github.com/powervr-graphics/Native_SDK) for running several sample applications.
80
81[googletest](third_party/googletest/) contains the [Google Test](https://github.com/google/googletest) project, as a Git submodule. It is used for running unit tests for Chromium, and Reactor unit tests. Run `git submodule update --init` to obtain/update the code. Any contributions should be made upstream.
