Specifically, information regarding screen size, pixel density, and frame-buffer properties such as color-depth, depth/stencil buffers, and anti-aliasing capabilities can all be found within this class. As with other common modules, access is provided via static fields of the <a href="https://javadoc.io/doc/com.badlogicgames.gdx/gdx/latest/com/badlogic/gdx/Gdx.html">Gdx class</a>.</p> <h1 id="opengl-context">OpenGL Context</h1> <p>A particular use of this module concerns more direct access to the current OpenGL context for lower-level commands and queries.</p> <p>The following example accesses the context in an OpenGL ES2 application to set the viewport and clear the frame and depth buffers:</p> <div class="language-java highlighter-rouge"><div class="highlight"><pre class="highlight"><code><span class="nc">Gdx</span><span class="o">.</span><span class="na">gl20</span><span class="o">.</span><span class="na">glViewport</span><span class="o">(</span> <span class="mi">0</span><span class="o">,</span> <span class="mi">0</span><span class="o">,</span> <span class="nc">Gdx</span><span class="o">.</span><span class="na">graphics</span><span class="o">.</span><span class="na">getWidth</span><span class="o">(),</span> <span class="nc">Gdx</span><span class="o">.</span><span class="na">graphics</span><span class="o">.</span><span class="na">getHeight</span><span class="o">()</span> <span class="o">);</span> <span class="nc">Gdx</span><span class="o">.</span><span class="na">gl20</span><span class="o">.</span><span class="na">glClearColor</span><span class="o">(</span> <span class="mi">0</span><span class="o">,</span> <span class="mi">0</span><span class="o">,</span> <span class="mi">0</span><span class="o">,</span> <span class="mi">1</span> <span class="o">);</span> <span class="nc">Gdx</span><span class="o">.</span><span class="na">gl20</span><span class="o">.</span><span class="na">glClear</span><span class="o">(</span> <span class="no">GL20</span><span class="o">.</span><span class="na">GL_COLOR_BUFFER_BIT</span> <span class="o">|</span> <span class="no">GL20</span><span class="o">.</span><span class="na">GL_DEPTH_BUFFER_BIT</span> <span class="o">);</span> </code></pre></div></div> <p>Note the use of <code class="language-plaintext highlighter-rouge">getWidth()</code> / <code class="language-plaintext highlighter-rouge">getHeight()</code> to access the current application window dimensions in setting the viewport as well as the use of constants from the <code class="language-plaintext highlighter-rouge">GL20</code> class just as one would do in a regular OpenGL program. A key advantage in libGDX is the ability to access low level functionality whenever higher level abstraction does not suffice.</p> <p>Each version of OpenGL ES is available through its own respective interface as well as a GLCommon ( <strong>that doesn’t exist, this article needs to be rewritten!</strong> ) interface for version agnostic commands. Note that use of <a href="https://javadoc.io/doc/com.badlogicgames.gdx/gdx/latest/com/badlogic/gdx/graphics/GL20.html">GL20</a> requires instructing the application to use OpenGL ES2 upon start-up.</p> <p>Access to the OpenGL Utility class ( <strong>that doesn’t exist, this article needs to be rewritten!</strong> ) is also provided, although this functionality may be better handled through Libgdx’s own <a href="https://github.com/libgdx/libgdx/tree/master/gdx/src/com/badlogic/gdx/graphics/OrthographicCamera.java">Orthographic</a> and <a href="https://github.com/libgdx/libgdx/tree/master/gdx/src/com/badlogic/gdx/graphics/PerspectiveCamera.java">Perspective</a> camera classes. There is also a simple method for querying support for named extensions in <code class="language-plaintext highlighter-rouge">supportsExtension()</code>. Just supply the name of the extension to determine support on the current device.</p> <h1 id="frame-time">Frame Time</h1> <p>One particularly useful method in the Graphics class is <code class="language-plaintext highlighter-rouge">getDeltaTime()</code>, which provides the time elapsed since the last rendered frame. This can be useful for time-based animation when frame independence is not necessary. For instance <a href="https://github.com/libgdx/libgdx/tree/master/gdx/src/com/badlogic/gdx/scenes/scene2d/Actor.java">Actor</a> or <a href="https://github.com/libgdx/libgdx/tree/master/gdx/src/com/badlogic/gdx/#gdx%2Fscenes%2Fscene2d%2Fui">UI</a> animation in a <a href="https://github.com/libgdx/libgdx/tree/master/gdx/src/com/badlogic/gdx/scenes/scene2d/Stage.java">Stage</a> instance might be controlled by a call such as the following in the application’s render method:</p> <div class="language-java highlighter-rouge"><div class="highlight"><pre class="highlight"><code><span class="n">stage</span><span class="o">.</span><span class="na">act</span><span class="o">(</span> <span class="nc">Math</span><span class="o">.</span><span class="na">min</span><span class="o">(</span> <span class="nc">Gdx</span><span class="o">.</span><span class="na">graphics</span><span class="o">.</span><span class="na">getDeltaTime</span><span class="o">(),</span> <span class="mi">1</span><span class="o">/</span><span class="mi">30</span> <span class="o">)</span> <span class="o">);</span> </code></pre></div></div> <p>Notice the use of a maximum time step of 1/30 seconds. This is to avoid potentially large jerks in the resulting animation. This illustrates the fact that while <code class="language-plaintext highlighter-rouge">getDeltaTime()</code> can be useful for simple animations, it is still frame dependent and more sensitive actions such as game logic or physics simulation may benefit from <a href="https://gafferongames.com/post/fix_your_timestep/">other timing strategies</a>.</p> <p>Another useful method is <code class="language-plaintext highlighter-rouge">getFramesPerSecond()</code>, which returns a running average of the current frame-rate for simple diagnostic purposes. However for more serious profiling efforts, the use of <a href="https://github.com/libgdx/libgdx/tree/master/gdx/src/com/badlogic/gdx/graphics/FPSLogger.java">FPSLogger</a> is recommended.</p> <h1 id="platform-differences">Platform Differences</h1> <p>On the desktop, the Graphics class also provides the ability to set a window’s icon and title values. Obviously these methods have no effect on platforms which lack an icon or title.</p> <p>The methods <code class="language-plaintext highlighter-rouge">setDisplayMode()</code> and <code class="language-plaintext highlighter-rouge">setVSync()</code> set the display mode to full-screen/windowed and enable/disable vertical display sync respectively. Keep in mind these methods have effects only on certain platforms.</p> <aside class="sidebar__right"> <div class="toc"> <div class="wiki_toc__menu"> <input id="wiki_ac-toc" name="accordion-toc"
