<div class="textblock"><p>WebGL support class. </p>
<p>The <a class="el" href="classWt_1_1WGLWidget.html" title="WebGL support class.">WGLWidget</a> class is an interface to the HTML5 WebGL infrastructure. Its implementation started based on the working drafts of the Khronos group, and will be updated as the standard stabilizes. To fully understand WebGL, it is recommended to read the WebGL standard in addition to this documentation.</p>
<p>The most recent version of the WebGL specification can be found here: <a href="https://cvs.khronos.org/svn/repos/registry/trunk/public/webgl/doc/spec/WebGL-spec.html">https://cvs.khronos.org/svn/repos/registry/trunk/public/webgl/doc/spec/WebGL-spec.html</a></p>
<p>This widget is work in progress. The API may change in the future because of new features, reorganizations or changes in the WebGL draft.</p>
<p>The goal of the <a class="el" href="classWt_1_1WGLWidget.html" title="WebGL support class.">WGLWidget</a> class is to provide a method to render 3D structures in the browser, where rendering and rerendering is normally done at the client side in JavaScript without interaction from the server, in order to obtain a smooth user interaction. Unless the scene requires server-side updates, there is no communication with the server.</p>
<p>The rendering interface resembles to OpenGL ES, the same standard as WebGL is based on. This is a stripped down version of the normal OpenGL as we usually find them on desktops. Many stateful OpenGL features are not present in OpenGL ES: no modelview and camera transformation stacks, no default lighting models, no support for other rendering methods than through VBOs, ... Therefore much existing example code for OpenGL applications and shaders will not work on WebGL without modifications. The 'learning webgl' web site at <a href="http://learningwebgl.com/">http://learningwebgl.com/</a> is a good starting point to get familiar with WebGL.</p>
<p>To use a WGLWidget, you must derive from it and reimplement the painter methods. Usually, you will always need to implement <a class="el" href="classWt_1_1WGLWidget.html#a173846477e42933b8cfd342db5de116e" title="Initialize the WebGL state when the widget is first shown.">initializeGL()</a> and <a class="el" href="classWt_1_1WGLWidget.html#a867c0405122daeb78dad8a013c91f004" title="Update the client-side painting function.">paintGL()</a>. Optionally, you may choose to implement <a class="el" href="classWt_1_1WGLWidget.html#a81c3bc38f708aec828ea1d1cf698633a" title="Act on resize events.">resizeGL()</a> (if your widget does not have a fixed size), and <a class="el" href="classWt_1_1WGLWidget.html#aac1505244222b8425bbd2f0a36c67545" title="Update state set in initializeGL()">updateGL()</a>. If you need to modify the painting methods, a repaint is triggered by calling the <a class="el" href="classWt_1_1WGLWidget.html#a889b8cb36667335045d0886b76d3e1b3" title="Request invocation of resizeGL, paintGL and/or updateGL.">repaintGL()</a> method. The default behaviour for any of these four painting functions is to do nothing.</p>
<p>The four painter methods (<a class="el" href="classWt_1_1WGLWidget.html#a173846477e42933b8cfd342db5de116e" title="Initialize the WebGL state when the widget is first shown.">initializeGL()</a>, <a class="el" href="classWt_1_1WGLWidget.html#a81c3bc38f708aec828ea1d1cf698633a" title="Act on resize events.">resizeGL()</a>, <a class="el" href="classWt_1_1WGLWidget.html#a867c0405122daeb78dad8a013c91f004" title="Update the client-side painting function.">paintGL()</a> and <a class="el" href="classWt_1_1WGLWidget.html#aac1505244222b8425bbd2f0a36c67545" title="Update state set in initializeGL()">updateGL()</a>) all record JavaScript which is sent to the browser.

<p>There are four painting methods that you may implement in a specialization of this class. The purpose of these functions is to register what JavaScript code has to be executed to render a scene. Through invocations of the WebGL functions documented below, <a class="el" href="namespaceWt.html" title="The namespace for Wt.">Wt</a> records the JavaScript calls that have to be invoked in the browser. </p>
<ul>
<li>
<b><a class="el" href="classWt_1_1WGLWidget.html#a173846477e42933b8cfd342db5de116e" title="Initialize the WebGL state when the widget is first shown.">initializeGL()</a></b>: this function is executed only once, right after the successful detection of WebGL in the browser. (note: in future versions, it may be re-executed when the webglcontextlost signal is fired, but this is currently not yet implemented). This is the ideal location to compose shader programs, send VBO's to the client, extract uniform and attribute locations, ... Due to the presence of VBO's, this function may generate a large amount of data to the client. </li>
<li>
<b><a class="el" href="classWt_1_1WGLWidget.html#a81c3bc38f708aec828ea1d1cf698633a" title="Act on resize events.">resizeGL()</a></b>: this function is executed whenever the canvas dimensions change. A change in canvas size will require you to invoke the <a class="el" href="classWt_1_1WGLWidget.html#a507e325d11e91fda58285388adf49d81" title="GL function to set the viewport.">viewport()</a> function again, as well as recalculate the projection matrices (especially when the aspect ratio has changed). The <a class="el" href="classWt_1_1WGLWidget.html#a81c3bc38f708aec828ea1d1cf698633a" title="Act on resize events.">resizeGL()</a> function is therefore the ideal location to set those properties. The <a class="el" href="classWt_1_1WGLWidget.html#a81c3bc38f708aec828ea1d1cf698633a" title="Act on resize events.">resizeGL()</a> function is invoked automatically on every resize, and after the first <a class="el" href="classWt_1_1WGLWidget.html#a173846477e42933b8cfd342db5de116e" title="Initialize the WebGL state when the widget is first shown.">initializeGL()</a> invocation. Additional invocations may be triggered by calling repaint() with the RESIZE_GL flag. </li>
<li>
<b><a class="el" href="classWt_1_1WGLWidget.html#a867c0405122daeb78dad8a013c91f004" title="Update the client-side painting function.">paintGL()</a></b>: this is the main scene drawing function. Through its execution, <a class="el" href="namespaceWt.html" title="The namespace for Wt.">Wt</a> records what has to be done to render a scene, and it is executed every time that the scene is to be redrawn. You can use the VBO's and shaders prepared in the <a class="el" href="classWt_1_1WGLWidget.html#a173846477e42933b8cfd342db5de116e" title="Initialize the WebGL state when the widget is first shown.">initializeGL()</a> phase. Usually, this function sets uniforms and attributes, links attributes to VBO's, applies textures, and draws primitives. You may also create local programs, buffers, ... Remeber that this function is executed a lot of times, so every buffer/program created in this function should also be destroyed to avoid memory leaks. This function is transmitted once to the client, and is executed when the scene needs to be redrawn. Redraws may be triggered from mouse events, timer triggers, events on e.g. a video element, or whatever other event. The <a class="el" href="classWt_1_1WGLWidget.html#a867c0405122daeb78dad8a013c91f004" title="Update the client-side painting function.">paintGL()</a> function can be updated through invoking <a class="el" href="classWt_1_1WGLWidget.html#a889b8cb36667335045d0886b76d3e1b3" title="Request invocation of resizeGL, paintGL and/or updateGL.">repaintGL()</a> with the PAINT_GL flag. </li>
<li>

If you want to change, add, remove or reconfigure those properties, the execution of an <a class="el" href="classWt_1_1WGLWidget.html#aac1505244222b8425bbd2f0a36c67545" title="Update state set in initializeGL()">updateGL()</a> function can be triggered by invoking <a class="el" href="classWt_1_1WGLWidget.html#a889b8cb36667335045d0886b76d3e1b3" title="Request invocation of resizeGL, paintGL and/or updateGL.">repaintGL()</a> with the UPDATE_GL flag. This signals that <a class="el" href="classWt_1_1WGLWidget.html#aac1505244222b8425bbd2f0a36c67545" title="Update state set in initializeGL()">updateGL()</a> needs to be evaluated - just once. It is possible that the <a class="el" href="classWt_1_1WGLWidget.html#a867c0405122daeb78dad8a013c91f004" title="Update the client-side painting function.">paintGL()</a> function also requires updates as consequence of the changes in the <a class="el" href="classWt_1_1WGLWidget.html#aac1505244222b8425bbd2f0a36c67545" title="Update state set in initializeGL()">updateGL()</a> function; in this case, you should also set the PAINT_GL flag of <a class="el" href="classWt_1_1WGLWidget.html#a889b8cb36667335045d0886b76d3e1b3" title="Request invocation of resizeGL, paintGL and/or updateGL.">repaintGL()</a>. </li>
</ul>
<p>The WebGL functions are intended to be used exclusively from within the invocation of the four callback functions mentioned above. In order to manually trigger the execution of these function, use the <a class="el" href="classWt_1_1WGLWidget.html#a889b8cb36667335045d0886b76d3e1b3" title="Request invocation of resizeGL, paintGL and/or updateGL.">repaintGL()</a>.</p>
<p>A <a class="el" href="classWt_1_1WGLWidget.html" title="WebGL support class.">WGLWidget</a> must be given a size explicitly, or must be put inside a layout manager that manages its width and height. The behaviour of a <a class="el" href="classWt_1_1WGLWidget.html" title="WebGL support class.">WGLWidget</a> that was not given a size is undefined.</p>
<h3>Client side matrices.</h3>
<p>The <a class="el" href="classWt_1_1WGLWidget.html" title="WebGL support class.">WGLWidget</a> provides the <a class="el" href="classWt_1_1WGLWidget_1_1JavaScriptMatrix4x4.html" title="A client-side JavaScript matrix.">WGLWidget::JavaScriptMatrix4x4</a> class as a mechanism to use client-side modifiable matrices in the render functions. These matrices can be used identically to the 'constant', with the advantage that there is no need to have a roundtrip to the server to redraw the scene when they are changed. As such, they are ideal for mouse-based camera manipulations, timer triggered animations, or object manipulations.</p>
<p>Note: the client side matrices are currently not yet communicated back to the server, but that is an implementation idea for the future. </p>

<li>a <em>block</em> widget takes by default the width of the parent, and the height that it needs based on its contents</li>
<li>an <em>inline</em> widget takes the width and height that it needs based on its contents (possibly wrapping over multiple lines). The width and height of an inline widget cannot be changed (by the letter of CSS, although most browsers will react to it in varying ways).</li>
</ul>
<p>When inserted in a layout manager, the size set will be used as a widget's preferred size, but the widget may be given a different size by the layout manager based on available space and stretch factors. The actual size given by a layout manager may be retrieved by making the widget "layout size aware", using <a class="el" href="classWt_1_1WWidget.html#a4f83592912a7f8fa4fd35dadde78ee74" title="Sets the widget to be aware of its size set by a layout manager.">setLayoutSizeAware()</a>. If you have defined a <code>"wtResize()"</code> JavaScript method for the widget, then this method will also be called.</p>
<p>The default width and height of a widget is <a class="el" href="classWt_1_1WLength.html#a0cf39ca4225776879d56ade60320c31a" title="An 'auto' length.">WLength::Auto</a>.</p>
