Greetings.
I have cocos3d's EAGLView and some UIKit controls over it.
Its important to know what's the cost of such configuration in terms of perfomance/fps. Does anyone know?
How big perfomance drop from intersection of UIKit controls and EAGLView is?

Unfortunately, this is a classic case of "your milage may vary"...as it all depends on what you need to do with the combination...and the only way to know it to try.
You will have at least two
UIViews, so the CA environment needs to merge them together during presentation. Apple promises that this is not a big issue.If the UIViews are doing a lot of work, then they might steal CPU cycles.
If you just want a button, or something simple, then consider using a 2D
CCMenu, etc.If you're presenting other
UIViewControllerson top ofCC3UIViewController, thenCC3UIViewControllermay reduce the FPS on purpose, and you may want to override this. Have a look at theCC3UIViewControllerimplementation for more on this....Bill

MemberI have main UIView with toolbar and inside that view EAGLView as subview. Over EAGLView I have 5-6 UIKit's buttons that overlap it.
How do you think, can such configuration seriously affect cocos3d fps, or I shouldn't worry and must not replace UIKit buttons with cocos2s layers?

MemberThat's how I do it:
1. Use only one GLKit view at the same time.
2. If your app is game, place GLKit view in root view controller and show other controllers modally, so you don't have to re-initialize the scene/opengl.
3. When viewcontroller with EAGLView will appear/disappear - pause (stopAnimation) the cocos rendering or resume it.Posted 4 months ago #
