+<p>The <a href="/en-US/docs/Web/API/WebGL_API">WebGL API</a> provides several constants that are passed into or returned by functions. All constants are of type {{domxref("GLenum")}}.</p>
+
+<p>Standard WebGL constants are installed on the {{domxref("WebGLRenderingContext")}} and {{domxref("WebGL2RenderingContext")}} objects, so that you use them as <code>gl.CONSTANT_NAME</code>:</p>
+
+<pre class="brush: js">var canvas = document.getElementById('myCanvas');
+var gl = canvas.getContext('webgl');
+
+gl.getParameter(gl.LINE_WIDTH);
+</pre>
+
+<p>Some constants are also provided by <a href="/en-US/docs/Web/API/WebGL_API/Using_Extensions">WebGL extensions</a>. A <a href="#Constants_defined_in_WebGL_extensions">list</a> is provided below.</p>
+
+<pre class="brush: js">var debugInfo = gl.getExtension('WEBGL_debug_renderer_info');
+var vendor = gl.getParameter(debugInfo.UNMASKED_VENDOR_WEBGL);</pre>
+
+<p>The <a href="/en-US/docs/Web/API/WebGL_API/Tutorial" title="WebGL tutorial">WebGL tutorial</a> has more information, examples, and resources on how to get started with WebGL.</p>

+
+<p>Shader programs have access to three kinds of data storage, each of which has a specific use case. Each kind of variable is accessible by one or both types of shader program (depending on the data store type) and possibly by the site's JavaScript code, depending on the specific type of variable.</p>
+
+<h2 id="Tipos_de_dados_GLSL">Tipos de dados GLSL</h2>
+
+<p>&lt;&lt;document the basic types, vectors, etc; see <a href="https://www.khronos.org/opengl/wiki/Data_Type_(GLSL)">Data Type (GLSL)</a> on the Khronos WebGL wiki&gt;&gt;</p>
+
+<h2 id="Variáveis_de_GLSL">Variáveis de GLSL</h2>
+
+<p>There are three kinds of "variable" or data storage available in GLSL, each of which with its own purpose and use cases: <strong>{{anch("Attributes", "attributes")}}</strong>, <strong>{{anch("Varyings", "varyings")}}</strong>, and <strong>{{anch("Uniforms", "uniforms")}}</strong>.</p>
+
+<h3 id="Atributos">Atributos</h3>
+
+<p><strong>Attributes</strong> are GLSL variables which are only available to the vertex shader (as variables) and the JavaScript code. Attributes are typically used to store color information, texture coordinates, and any other data calculated or retrieved that needs to be shared between the JavaScript code and the vertex shader.</p>
+
+<p>&lt;&lt;add how to use them&gt;&gt;</p>
+
+<h3 id="Varyings"><em>Varyings</em></h3>
+
+<p><strong>Varyings</strong> are variables that are declared by the vertex shader and used to pass data from the vertex shader to the fragment shader. This is commonly used to share a vertex's {{interwiki("wikipedia", "Normal_(geometry)", "normal vector")}} after it has been computed by the vertex shader.</p>
+
+<p>&lt;&lt;how to use&gt;&gt;</p>
+
+<h3 id="Uniforms"><em>Uniforms</em></h3>
+
+<p><strong>Uniforms</strong> are set by the JavaScript code and are available to both the vertex and fragment shaders. They're used to provide values that will be the same for everything drawn in the frame, such as lighting positions and magnitudes, global transformation and perspective details, and so forth.</p>

+<p>WebGL (Biblioteca de Gráficos da Web) é uma API de JavaScript para a renderização de gráficos 2D e 3D interativos dentro de qualquer navegador da Web compatível sem a utilização de plug-ins. WebGL fazi isso, ao introduzir uma API que está em conformidade com o OpenGL ES 2.0 que pode ser utilizado em elementos {{HTMLElement("canvas")}} de HTML5.</p>
+</div>
+
+<p>O suporte para WebGL está presente no <a href="/pt-PT/docs/Mozilla/Firefox" title="Firefox 4 for developers">Firefox</a> 4+, <a href="http://www.google.com/chrome/" title="http://www.google.com/chrome/">Google Chrome</a> 9+, <a href="http://www.opera.com/" title="http://www.opera.com/">Opera</a> 12+, <a href="http://www.apple.com/safari/" title="http://www.apple.com/fr/safari/">Safari </a>5.1+ and <a href="http://windows.microsoft.com/en-us/internet-explorer/browser-ie" title="http://windows.microsoft.com/en-us/internet-explorer/download-ie">Internet Explorer</a> 11+, e <a href="https://www.microsoft.com/pt-pt/windows/microsoft-edge">Microsoft Edge</a> build 10240+; contudo, o dispositivo do utilizador também deve ter hardware que suporte estas funcionalidades.</p>
+
+<p>O elemento {{HTMLElement("canvas")}} também é utilizado por <a href="/pt-PT/docs/Web/API/API_de_canvas">Canvas 2D</a> para gráficos 2D nas páginas da Web.</p>

+<p>In addition to the browser, the GPU itself also needs to support the feature. So, for example, S3 Texture Compression (S3TC) is only available on Tegra-based tablets. Most browsers make the WebGL context available through the <code>webgl</code> context name, but older ones need <code>experimental-webgl</code> as well. In addition, the upcoming <a href="/en-US/docs/Web/API/WebGL2RenderingContext">WebGL 2</a> is fully backwards-compatible and will have the context name <code>webgl2</code>.</p>

+
+<dl>
+ <dt><code>webgl.min_capability_mode</code></dt>
+ <dd>A Boolean property that, when <code>true</code>, enables a minimum capability mode. When in this mode, WebGL is configured to only support the bare minimum feature set and capabilities required by the WebGL specification. This lets you ensure that your WebGL code will work on any device or browser, regardless of their capabilities. This is <code>false</code> by default.</dd>

+
+<p>WebGL, like its sister APIs (OpenGL and OpenGL ES), supports extensions. A complete list of extensions is available in the <a class="external" href="http://www.khronos.org/registry/webgl/extensions/">khronos webgl extension registry</a>.</p>
+
+<div class="note"><strong>Nota:</strong> In WebGL, unlike in other GL APIs, extensions are only available if explicitly requested.</div>
+
+<h2 id="Nomes_de_extensão_canónica_prefixos_e_preferências_da_empresa">Nomes de extensão canónica, prefixos e preferências da empresa</h2>
+
+<p>Extensions may be supported by browser vendors before being officially ratified (but only when they are in draft stage). In that case, their name can be prefixed by the vendor prefix (<code>MOZ_</code>, <code>WEBKIT_</code>, etc.) or the extension is only available once a browser preference has been toggled.</p>
+
+<p>If you wish to work with the bleeding edge of extensions, and want to keep working on upon ratification (assuming, of course, that the extension doesn't change in incompatible ways), that you query the canonical extension name as well as the vendor extension name. For instance:</p>
+
+<pre class="brush:js">var ext = (
+ gl.getExtension('OES_vertex_array_object') ||
+ gl.getExtension('MOZ_OES_vertex_array_object') ||
+ gl.getExtension('WEBKIT_OES_vertex_array_object')
+);
+</pre>
+
+<p>Note that, vendor prefix have been discouraged more and more and thus most browser implement experimental extensions behind a feature flag rather than vendor prefix.</p>
+
+<p>The feature flags are:</p>
+
+<ul>
+ <li><code>webgl.enable-draft-extensions</code> in Firefox</li>
+ <li><code>chrome://flags/#enable-webgl-draft-extensions</code> in Chromium based browsers (Chrome, Opera).</li>
+</ul>
+
+<h2 id="Convenções_de_nomeação">Convenções de nomeação</h2>
+
+<p>WebGL extensions are prefixed with "ANGLE", "OES", "EXT" or "WEBGL". These prefixes reflect origin and intent:</p>
+
+<ul>
+ <li>ANGLE_: Extensions that are written by the <a href="https://en.wikipedia.org/wiki/ANGLE_%28software%29">ANGLE library</a> authors.</li>
+ <li>OES_: Extensions that mirror functionality from OpenGL ES or OpenGL API extensions approved by the respective architecture review boards.</li>
+ <li>EXT_: Extensions that mirror other OpenGL ES or OpenGL API extensions.</li>
+ <li>WEBGL_: Extensions that are WebGL-specific and intended to be compatible with multiple web browsers. It should also be used for extensions which originated with the OpenGL ES or OpenGL APIs, but whose behavior has been significantly altered.</li>
+</ul>
+
+<h2 id="Extensões_de_consulta_disponíveis">Extensões de consulta disponíveis</h2>
+
+<p>O contexto de WebGL suporta a consulta de quais as extensões que estão disponíveis.</p>
+
+<pre class="brush:js">var available_extensions = gl.getSupportedExtensions();</pre>
+
+<p>The {{domxref("WebGLRenderingContext.getSupportedExtensions()")}} method returns an array of strings, one for each supported extension.</p>
+
+<h2 id="Lista_de_extensões">Lista de extensões</h2>
+
+<p>As extensões atuais são:</p>
+
+<p>{{page("pt-PT/docs/Web/API/WebGL_API", "Extensões")}}</p>
+
+<h2 id="Ativar_uma_extensão">Ativar uma extensão</h2>
+
+<p>Before an extension can be used it has to be enabled using {{domxref("WebGLRenderingContext.getExtension()")}}. For example:</p>
+
+<pre class="brush:js">var float_texture_ext = gl.getExtension('OES_texture_float');</pre>
+
+<p>The return value is <code>null</code> if the extension is not supported, or an extension object otherwise.</p>
+
+<h2 id="Objetos_de_extensão">Objetos de extensão</h2>
+
+<p>If an extension defines specific symbols or functions that are not available in the core specification of WebGL, they will be available on the extension object returned by the call to <code>gl.getExtension()</code>.</p>
