| EGL Extension #?? |
| |
| Dependencies |
| |
| Requires EGL 1.4. |
| |
| Written against the EGL 1.4 specification. |
| |
| This spec interacts with GL_ANGLE_webgl_compatibility (or equivalent) |
| extension. |
| |
| Overview |
| |
| This extension allows the creation of an OpenGL or OpenGL ES context that |
| provides additional WebGL features and validation. |
| |

| |
| New Tokens |
| |
| Accepted as an attribute name in the <*attrib_list> argument to |
| eglCreateContext: |
| |
| EGL_CONTEXT_WEBGL_COMPATIBILITY_ANGLE 0x33AC |
| EGL_CONTEXT_HARDENED_ANGLE 0x34F8 |
| |
| Additions to the EGL 1.4 Specification |
| |
| Add the following to section 3.7.1 "Creating Rendering Contexts": |
| |
| EGL_CONTEXT_WEBGL_COMPATIBILITY_ANGLE indicates whether a WebGL mode should |
| be enabled for the OpenGL ES context. In this mode, the OpenGL ES context |
| will provide additional features and validation to be compatible with the |
| WebGL specification. The default value of |
| EGL_CONTEXT_WEBGL_COMPATIBILITY_ANGLE is EGL_FALSE. |
| |
| EGL_CONTEXT_HARDENED_ANGLE indicates whether additional hardening measures |
| should be applied, such as done by the shader translation. These hardening |
| measures are a subset of those enabled when |
| EGL_CONTEXT_WEBGL_COMPATIBILITY_ANGLE is EGL_TRUE, and so it has no effect |
| in that case. |
