| /* This header webgl1_ext.h provides static linkage entry points to all WebGL extensions that |
| the Khronos WebGL registry adds on top of the WebGL 1 API. |
| |
| In Emscripten, all GL extension function entry points are provided via static linkage. |
| For best WebGL performance, call the statically linked gl*() functions in this header |
| instead of using a dynamic function pointers via the glGetProcAddress() function. |
| |
| Include this header instead of the headers GLES2/gl2ext.h or GL/glext.h if you are |
| developing a WebGL renderer as a first tier platform, and want to get "fail fast" |
| compiler errors of GL symbols that are not supported on WebGL. |
| |
| Other features: |
| - If you want to use one of the WebGL specific extensions that do not exist in |
| GLES or desktop GL (such as WEBGL_lose_context or WEBGL_debug_shaders), include |
| this header to get the function declarations and defines. |
| |
| - Unlike GLES and desktop GL, in WebGL one must explicitly enable an extension |
| before using it. See below in the section of each extension for instructions |
| on how to enable it, or link with -sGL_SUPPORT_AUTOMATIC_ENABLE_EXTENSIONS=1 |
| to automatically enable all non-debugging related WebGL extensions at startup. |
| |
| - If you are targeting multiple Emscripten compiler versions (e.g. a rendering |
| library middleware), you can query whether static linkage to a particular |
| extension is provided, by including this header and then checking |
| |
| #if EMSCRIPTEN_GL_WEBGL_polygon_mode |
| // we can call glPolygonModeWEBGL() function |
| #endif |
| |
| - To disable a particular WebGL extension from being declared in this header, |
| you can add e.g. |
| #define EMSCRIPTEN_GL_OES_texture_float 0 |
| before including this header. |
| |
| - For technical reasons, each function declaration comes in two variants: |
| a glFoo() declaration, and a second emscripten_glFoo() copy. |
| The emscripten_glFoo() variants exist for internal *GetProcAddress() and |
| Emscripten -sOFFSCREEN_FRAMEBUFFER=1 features linkage purposes, and should |
| be ignored by end users. |
