Hi, I managed built this old repo on brand new macOS.
but I got something not fully right, could u help me a little bit?

the background scene can not fully show.

And I can not orbit the object using mouse.

And my Mac doesn't support shader higher than 410, can u help fix it?

I would be interested if there is a way to integrate this c++ engine into a mobile application. Let's assume we have an Android Application which provides access to C++ via the Java Native Interface, from the point of c++ code that should be no problem, but is OpenGLES 3.0 sufficient for it?

I am not experienced on the field of graphics coding, and wanted to get an overview about the possibilities before diving into the deep.

It's a common technique but if you pass the inverse world-view-projection matrix, you can sample your depth buffer and reconstruct position from it using the matrix. This will save significantly on your gbuffer size and improve performance as well, take a look at my project on here Neothyne to see how I go about that. Otherwise your engine looks nice, keep up the good work ;-)

I am trying to find a library that can "light up" my Model/Scene with a HDRI Ball Image.

Similar to this

Is this the library that does this?

Hi, can you tell me what part of your code is limiting the framerate to 50 fps. Whatever option i disable/enable it stays the same.
It seems like some framerate value from imgui is used for display, i dont see any place where this max fps value is set explicitly.

Thanks for your time.

BTW i like how everything is well organized in the glengine.cpp file, it makes things so much more simple to learn.
