I am new to culling. On a first glance, it seems that most occlusion culling algorithms are object-level, not examining single meshes, which would be practical for game rendering.
What I am looking for is an algorithm that culls all meshes within a single...

The renderer isn't actually rendering all of the buildings and structures, it's common for graphics API examples....
In general, it's because (1) the games are being optimal about what they need to render, and (2 from Grand Theft Auto IV.

This is something I've been looking into for while, but I have yet to find any concrete information or good examples. I have, say, a bunch of unconnected objects (triangle strips for instance). What is the efficient way to render these?

Note that performance might drop if your data changes each frame, since you then need to update the relevant portions of the data, which means copy them to the graphics card's... .
Look into glDrawElements() , it is one good way of achieving what you want .

You can render it to a screen with some shaders (e.g.

Hello,
I recently developed a binaural audio renderer (i.e. a binaural reverberator that works on multiple sources simultaneously) and am asking myself what I can do with it. I tried contacting game developers (personally I see games as the most obvious...
