You have made the standard comment that tells me I need a better video explanation. The primary goal is to decide what geometry to send right now, which is a different question than, "What optimization techniques can I use to cull geometry to speed up drawing a frame?"

Plenty of games already delivery content over the internet--think Minecraft--but they're loading entire areas in bulk. I'm trying to sent only what is visible right now, just-in-time.

I'm going to develop an Android client for the same scene next. I hope that will make the use case more obvious.
