Hi everybody,
i build an app that shows videos on top of the tags, and it works very well (I'm developing on iOS). But, now I want to show the EAGLView stuff on an external display but I can't. I slighly modified applicationDidFinishingLauchingWithOptions: like this:
- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions
{
QCARutils *qUtils = [QCARutils getInstance];
CGRect screenBounds ;
if ([[UIScreen screens] count] > 1)
{
// Associate the window with the second screen.
// The main screen is always at index 0.
UIScreen*secondScreen = [[UIScreenscreens] objectAtIndex:1];
CGRectscreenBounds = secondScreen.bounds;
UIWindow *_secondWindow;
_secondWindow = [[UIWindowalloc] initWithFrame:screenBounds];
_secondWindow.screen = secondScreen;
// Go ahead and show the window.
_secondWindow.hidden = NO;
window = _secondWindow;
}
else {
screenBounds = [[UIScreenmainScreen] bounds];
window = [[UIWindowalloc] initWithFrame: screenBounds];
}
// Provide a list of targets we're expecting - the first in the list is the default
[qUtils addTargetName:@"WonderBook" atPath:@"wonderbook.xml"];
if(![[UIApplication sharedApplication] isScreenMirroringActive]){
[[UIApplication sharedApplication] setupScreenMirroring];
}
// Add the EAGLView and the overlay view to the window
arParentViewController = [[VPParentViewController alloc] init];
arParentViewController.arViewRect = screenBounds;
[window insertSubview: arParentViewController.view atIndex:0];
[window makeKeyAndVisible];
[window layoutSubviews];
return YES;
I'm using this simple library that works well but is too slow 'cause doesn't use OpenGL but every frames is captured and shown on both display.Is there a simpler way to show everything that happens on main screen ([UIScreen mainScreen]) directly on another external screen and draw on it?
Thanks in advance
Best regards.
Using external projector to show OpenGL EAGLView
I guess the simplest way to achieve this is to run it on an iPad that is connected up to an external display via a simple cable.
... but maybe this is not what you want?

Yeah, exactly I have to use an iPhone (iPad should be too big)...

I had a quick look at the library you had a look to but could find no documentation :(
I guess at a high level (assuming its possible) there might be two approaches:

Solved.
I had to disable the [UIScreen mainScreen] and add the EAGLView to the ViewController attached to the UIWindow *externalWindow.
So everything now is drawn on the external display. And best of all, I don't need external mirroring class anymore.

That's awesome
great stuff! and thanks for sharing
