\r
SwiftShader 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.\r
\r
Usage\r
---------\r
+-----\r
\r
The SwiftShader libraries act as drop-in replacements for graphics drivers.\r
\r
On 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.\r

+Third-Party Dependencies\r
+------------------------\r
+\r
+The [third_party](third_party/) directory contains projects which originated outside of SwiftShader:\r
+\r
+[LLVM](third_party/LLVM/) contains an outdated and diverged copy of the [LLVM](http://llvm.org/) compiler framework.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.\r
+\r
+[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.\r
+\r
+[llvm-subzero](third_party/llvm-subzero/) contains a minimized set of LLVM dependencies of the Subzero project.\r
+\r
+[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.\r
+\r
+[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.\r
