Field Detail

EGL_PROTECTED_CONTENT_EXT

public static final int EGL_PROTECTED_CONTENT_EXT

In order to render protected content, EGL context and its resources should account for that. At creation time, the corresponding PROTECTED attribute should be set to EGL_TRUE. For more information, see EGL_EXT_protected_content EGL extension.

Method Detail

getSRGBConfig

public InputGLBinding.SRGBConfig getSRGBConfig()

onSurfaceCreated

public void onSurfaceCreated(GL10 gl10,
                             EGLConfig eConfig)

Description copied from interface: com.leia.sdk.views.LeiaGLSurfaceView.Renderer

Called when the surface is created or recreated.

Called when the rendering thread starts and whenever the EGL context is lost. The EGL context will typically be lost when the Android device awakes after going to sleep.

Since this method is called at the beginning of rendering, as well as every time the EGL context is lost, this method is a convenient place to put code to create resources that need to be created when the rendering starts, and that need to be recreated when the EGL context is lost. Textures are an example of a resource that you might want to create here.

Note that when the EGL context is lost, all OpenGL resources associated with that context will be automatically deleted. You do not need to call the corresponding "glDelete" methods such as glDeleteTextures to manually delete these lost resources.

Specified by:

onSurfaceCreated in interface com.leia.sdk.views.LeiaGLSurfaceView.Renderer

Parameters:

gl10 - the GL interface. Use instanceof to test if the interface supports GL11 or higher interfaces.

eConfig - the EGLConfig of the created surface. Can be used to create matching pbuffers.

onSurfaceChanged

public void onSurfaceChanged(GL10 gl10,
                             int width,
                             int height)

Description copied from interface: com.leia.sdk.views.LeiaGLSurfaceView.Renderer

Called when the surface changed size.

Called after the surface is created and whenever the OpenGL ES surface size changes.

Typically you will set your viewport here. If your camera is fixed then you could also set your projection matrix here:

 void onSurfaceChanged(GL10 gl, int width, int height) {
     gl.glViewport(0, 0, width, height);
     // for a fixed camera, set the projection too
     float ratio = (float) width / height;
     gl.glMatrixMode(GL10.GL_PROJECTION);
     gl.glLoadIdentity();
     gl.glFrustumf(-ratio, ratio, -1, 1, 1, 10);
 }
 

Specified by:

onSurfaceChanged in interface com.leia.sdk.views.LeiaGLSurfaceView.Renderer

Parameters:

gl10 - the GL interface. Use instanceof to test if the interface supports GL11 or higher interfaces.

onDrawFrame

public void onDrawFrame(GL10 gl10,
                        com.leia.sdk.views.LeiaGLSurfaceView.EglHelper eglHelper)

Description copied from interface: com.leia.sdk.views.LeiaGLSurfaceView.Renderer

Called to draw the current frame.

This method is responsible for drawing the current frame.

The implementation of this method typically looks like this:

 void onDrawFrame(GL10 gl) {
     gl.glClear(GL10.GL_COLOR_BUFFER_BIT | GL10.GL_DEPTH_BUFFER_BIT);
     //... other gl calls to render the scene ...
 }
 

Specified by:

onDrawFrame in interface com.leia.sdk.views.LeiaGLSurfaceView.Renderer

Parameters:

gl10 - the GL interface. Use instanceof to test if the interface supports GL11 or higher interfaces.
