[2.1] Where is SampleBrowser's GUI in Ogre 2.1? Topic is solved

[123iamking]

According to this article

The SampleBrowser is part of the 1.x samples. These are not the 2.1 samples.

So the SampleBrowser is for Ogre 1.x. But how about the GUI of the SampleBrowser. I see that the OgreBites is responsible for the GUI, but I can't find OgreBites in Ogre 2.1 source.
So I'm curious a couple of things about the simple GUI (or simply Overlay) system in Ogre 2.1

• Why is the Overlay system decided to put inside the v1 namespace? (I try to read AZDO changes but I still don't understand clearly - just understand vaguely that it's not ported yet (but which part is incompatible?). Also what is the consequence when I try to use it (for example: slow performance,...))
• Why is the GUI (OgreBites namespace) excluded from Ogre 2.1? (What's make it incompatible?)

Thanks for reading

I see that the OgreBites is responsible for the GUI, but I can't find OgreBites in Ogre 2.1 source.

OgreBites was complex to support or maintain (mostly because of Overlay's aging design), and relied on Overlay component.

It hasn't been ported, thus it hasn't ideal performance. The problem is that if the v1 buffer mapping hits a slow path, it could cause stalls (thus slowing everything down).
Overlay has many small details to improve it would be best to just write a new one, just nobody has one. Making good GUIs is hard and everyone uses a different solution.

IIRC OgreBites didn't rely on anything that was removed, so it should probably be possible to port it to 2.1 without too much effort; but there isn't much interest shown so far.

Hi dark_sylinc, I want to ask you a personal question What GUI library are you using for your current project (I notice a game you are developing called Distant Souls)
