Method once, when creating the GLSurfaceView.

onSurfaceCreated(): The system calls this.

The GLSurfaceView.Renderer interface requires that you implement the Separate class and attach it to your GLSurfaceView instance using You must provide an implementation of this interface as a GLSurfaceView.Renderer This interface defines the methods required for drawing graphics in an OpenGL GLSurfaceView. Implement the touch listeners, as shown in OpenGL Tutorials forĮS 2.0 and the TouchRotateActivity sample. Touch screen events, you should extend the GLSurfaceView class to This class by creating an instance of GLSurfaceView and adding your OpenGL API calls and is similar in function to a SurfaceView. GLSurfaceView This class is a View where you can draw and manipulate objects using Understanding how to implement these classes in an activity should be your first objective. If your goal is to use OpenGL in your Android application, Graphics with the OpenGL ES API: GLSurfaceView and GLSurfaceView.Renderer. There are two foundational classes in the Android framework that let you create and manipulate This topic focuses on the Android framework interfaces. The BasicsĪndroid supports OpenGL both through its framework API and the Native Development J2ME JSR239 OpenGL ES API, but is not identical. Note: The specific API provided by the Android framework is similar to the Beginning with Android 2.2 (API Level 8), the framework supports the The OpenGL ES 1.0 and 1.1 API specifications have been Specification intended for embedded devices.

Standard software interface for 3D graphics processing hardware. OpenGL is a cross-platform graphics API that specifies a (OpenGL), specifically, the OpenGL ES API. OpenGL Versions and Device CompatibilityĪndroid includes support for high performance 2D and 3D graphics with the Open Graphics Library.This lesson explains how to draw the shapes you defined in the previous lesson using the OpenGLīefore you do any drawing, you must initialize and load the shapes you plan to draw. Great deal of control over the graphics rendering pipeline. With the OpenGL ES 2.0 takes a bit more code than you might imagine, because the API provides a After you define shapes to be drawn with OpenGL, you probably want to draw them.
