Android OpenGl Renderer finish event
- by Eu Vid
In OpenGL Renderer onDrawFrame is called several time, until the page is completely rendered. I cannot find an event that my page is completeley rendered in order to take a snapshot of the OpenGL page and animate it.
I have the solution to take snapshot on at the animation trigger (specific button), but this will imply a specific delay, until Bitmap is created, such as i would like to keep in memory a mutable copy of every page.
Do you know other way to animate GLSurfaceView with rendered content?
Snippet for triggering snapshot.
glSurfaceView.queueEvent(new Runnable() {
@Override
public void run() {
glSurfaceView.getRenderer().takeGlSnapshot();
}
});
EGLContext for passing the GL11 object.
public void takeGlSnapshot() {
EGL10 egl = (EGL10) EGLContext.getEGL();
GL11 gl = (GL11) egl.eglGetCurrentContext().getGL();
takeSnapshot(gl);
}
onDrawFrame(Gl10 gl) {
//is last call for this page event ????????????
