| 24 Comments in this extension template are highlighted in green. This entir
e section is one big | |
| 25 comment. | |
| 26 </p> | |
| 27 <p> | |
| 28 This template for WebGL extensions is derived from | |
| 29 the <a href="http://www.opengl.org/registry/doc/template.txt">OpenGL ext
ension template</a>. | |
| 30 Refer to the OpenGL extension template for full documentation of the con
tent that should be | |
| 31 contained in the sections below. Because WebGL is fundamentally a Web AP
I, its extensions | |
| 32 are specified in HTML for easier hyperlinking. | |
| 33 </p> | |
| 34 <p> | |
| 35 Because most WebGL extensions are expected to simply mirror existing Ope
nGL and OpenGL ES | |
| 36 extensions, it is desirable to keep the WebGL extension specifications a
s small as possible | |
| 37 and simply refer to the other specifications for the behavioral definiti
ons. | |
| 38 </p> | |
| 39 </div> | |
| 40 | |
| 41 <h2 class="no-toc">Name</h2> | |
| 42 <div class="nonnormative"> | |
| 43 <p> | |
| 44 The name of the extension. This is also the string which is passed to | |
| 45 the <code>WebGLRenderingContext</code> <code>getExtension</code> API to en
able the | |
| 46 extension. For example, if the extension name were <code>OES_texture_float
</code>, then the | |
| 47 extension would be fetched and enabled with a call | |
| 48 to <code>getExtension("OES_texture_float")</code>. | |
| 49 </p> | |
| 50 <p> | |
| 51 Per WebGL convention, the <code>GL_</code> prefix is dropped from all exte
nsion and enum names, and the | |
| 52 <code>gl</code> prefix dropped from, and capitalization adjusted of, all f
unction names. | |

| 98 | |
| 99 <div class="nonnormative"> | |
| 100 <p> | |
| 101 A description of what this extension actually does. If this extension simp
ly mirrors an OpenGL | |
| 102 or OpenGL ES extension, it is recommended to simply link to that other ext
ension's | |
| 103 specification. For example: | |
| 104 </p> | |
| 105 <p> | |
| 106 This extension exposes the | |
| 107 <a href="http://www.khronos.org/registry/gles/extensions/OES/OES_texture_f
loat.txt">OES_texture_float</a> | |
| 108 functionality to WebGL. There are no WebGL-specific behavioral changes. C
onsult the above | |
| 109 extension for all documentation, issues, and new functions and enumerants. | |
| 110 </p> | |
| 111 </div> | |
| 112 | |
| 113 <h2 class="no-toc">IDL</h2> | |
| 114 | |
| 115 <div class="nonnormative"> | |
| 116 <p> | |
| 117 This section should contain the inline Web IDL for the extension, surround
ed by the | |
| 118 tags <code><pre class="idl">...</pre></code>. Enums and functi
ons introduced by | |
| 119 the extension should be specified as <code>const GLenum</code> and methods
on the extension | |
| 120 object. The extension IDL should be written assuming that the typedefs | |
| 121 in <code><a href="../../specs/latest/webgl.idl">webgl.idl</a></code> | |
| 122 and <code><a href="../../typedarray/specs/latest/typedarrays.idl">typedarr
ays.idl</a></code> | |
| 123 have already been defined, and may implicitly reference other web platform
specifications. | |
