What is ANGLE?

ANGLE allows Windows users to seamlessly run OpenGL ES content by efficiently translating OpenGL ES API into DirectX 11 API calls.

The ms-master branch in this repository is maintained by Microsoft to support the use of ANGLE by Windows Store app developers. It contains:

  • A copy of ANGLE that is regularly updated from the ANGLE master branch
  • Recent changes made by Microsoft that have not yet been merged back to ANGLE master (our goal is to eventually merge everything, but if you want the latest and greatest Windows Store features, you will find them here first)
  • Documentation and project templates focused on Windows Store app development
  • Sample code and utilities such as DDS and WIC texture loaders
  • This branch is the source for building the ANGLE binaries that we publish on NuGet

ANGLE fully supports these C++ app types:

  • Universal Windows apps (Windows 10)
  • Windows 8.1 and Windows Phone 8.1 apps
  • Windows desktop applications

Experimental support for HoloLens is available in a dedicated branch found here.


What versions of OpenGL ES does ANGLE support?

ANGLE supports different versions of OpenGL ES depending on the capabilities of the underlying hardware. In particular, the supported version depends on which D3D Feature Levels the hardware supports:

Hardware
Feature Levels
Example devices What does ANGLE support?
11_1
11_0
10_1
10_0
Modern Desktop PCs
Surface Pros
OpenGL ES 2.0
Parts of OpenGL ES 3.0
9_3 Windows Phones OpenGL ES 2.0 (except minor corner cases)
9_2
9_1
Surface RT OpenGL ES 2.0 (via software emulation)
None Raspberry Pi 2 OpenGL ES 2.0 (via software emulation)

Getting ANGLE

There are three ways to get ANGLE for Windows Store applications:

  1. Use Visual Studio 2015's OpenGL ES template, targeting Windows (via ANGLE), iOS and Android
  2. Download compiled ANGLE binaries as a NuGet package. Instructions are available here
  3. Download and compile the ANGLE source code from this GitHub repository

Option 3 has also includes some additional Visual Studio app templates:


Requirements for using ANGLE

Windows 10 Development:

Windows 8.1 and/or Windows Phone 8.1 Development:

  • Visual Studio Community 2013 (Update 4), or higher/later.
  • Windows 8.1 for local Windows development.

Clasic Windows (Desktop) Development:

  • Visual Studio 2015 Community or higher.

Quick start from source

  1. Clone or download ANGLE from our GitHub repository
  2. Install our easy-to-use Visual Studio templates by running install.bat in the /templates/ directory of your copy of ANGLE, or follow these manual steps.
  3. Open the appropriate ANGLE Visual Studio solution for your project, and build all flavors of it
  4. In Visual Studio go "File -> New -> Project", create a new ANGLE application, and hit F5 to run it!

The Windows 10 Visual Studio solution for ANGLE is located here:

  • /winrt/10/src/angle.sln

The Windows 8.1 Visual Studio solutions for ANGLE are located here:

  • /winrt/8.1/windows/src/angle.sln
  • /winrt/8.1/windowsphone/src/angle.sln

The Visual Studio solution for Windows desktop applications is located here:

  • /src/angle.sln

Improve your ANGLE app's performance

Here is a list of best practices for using ANGLE on Windows devices.


Known issues and Breaking Changes

Here are the known issues with ANGLE, which we are either trying to fix or are unable to fix.

Here are the recent breaking changes that we have made, which might affect your app if you update to the latest version of ANGLE.


Contributing to ANGLE

If you wish to contribute to ANGLE, then please contribute to the master version of ANGLE. Your change can then be merged back into Microsoft/angle.
