This functionality is -accessed via the OpenGL API — specifically, the OpenGL ES API.</p> - -<p>OpenGL ES is a flavor of the OpenGL specification intended for embedded -devices. Versions of OpenGL ES are loosely peered to versions of the primary -OpenGL standard. Android currently supports OpenGL ES 1.0, which corresponds -to OpenGL 1.3. So, if the application you have in mind is possible with OpenGL -1.3 on a desktop system, it should be possible on Android.</p> - -<p>The specific API provided by Android is similar to the J2ME JSR239 OpenGL -ES API. However, it may not be identical, so watch out for deviations.</p> - -<h2>Using the API</h2> - -<p>Here's how to use the API at an extremely high level:</p> - -<ol> -<li>Write a custom View subclass.</li> -<li>Obtain a handle to an OpenGLContext, which provides access to the OpenGL functionality.</li> -<li>In your View's onDraw() method, get a handle to a GL object, and use its methods to perform GL operations.</li> -</ol> - -<p>For an example of this usage model (based on the classic GL ColorCube), -see -<a href="{@docRoot}samples/ApiDemos/src/com/example/android/apis/graphics/GLView1.html">com.android.samples.graphics.GLView1.java</a> -in the ApiDemos sample code project.
