Wow, this is so unbelievably unoptimized. The sound of my computer fans makes it so immersive. The shadow map is being rendered twice with 300+ draw calls and 1M+ triangles. Full resolution GTAO is probably even more expensive with a lot of fetches per texel. I'm sure there are a ton of low hanging optimization fruits and I'm confident claude et. al can fix all those issues, but if you don't know where to look and ne…

It's a work in progress. I have cut down on the original mesh size by quite a bit but continue to do that. I also fade out the resolution of the map tiles as you approach the horizon so you aren't loading ihgher res satellite images than you need. I've run entire flights on my 2022 mac pro with no issue, but as this is a side project it remains not as optimal as it could be. Any suggestions for order of operations /…

I have a few suggestions:

- as I mentioned above, the shadow map is drawn twice, probably it's being auto updated by three.js at some point

- the entire cabin has a lot of triangles while the player only sees a small portion of it

- cabin lighting could be baked

- a lot of triangles seem to be rendered without backface culling, that's probably not intentional

- don't run GTAO at full resolution, try half

And also, use the spector.js [1] browser extension to profile the app and have your AI agent analyze the capture.

Kindly simulate two hours of queuing at the Schengen border, a coin toss minigame over whether security is “laptops in” or “laptops out”, bonus if your belt pings, lounge access roulette, wailing infant(s), guy two rows back with the worst most productive cough you ever heard (still got that old N95?), retaining status planning spreadsheets, baggage systems failure at Denver, people using the loos in their socks, uns…

you missed (not a complete list): the TSA travelling over to your country to give to their "was it as good for you as it was for me" inspection on your home soil, the non stop 16h conversation between two strangers right behind you, 45min of bus ride following the 30min of taxi, followed by catching an uber between the international and domestic terminals, carry-on luggage overhead tetris, people somehow coming on the plane with 4 or 5 large pieces of carry-on, the "can you swap seats with me and my middle seat because my partner/child is next to you" tap on the shoulder, the "Missed The Tight Connection" walk of shame, the overnight in a cheap hotel miles out of town because it was the airlines fault, the body odour buddy, the snorer, the last minute departure gate change, the 2h on the tarmac at ATL due to thunder storms, and the ironic applause when a nervous pilot puts you all down rather bumpily.

Gait recognition, too?

Googling "gtao graphics" results in "Grand theft auto online"

"Gtao technique" was more helpful: Ground Truth Ambient Occlusion

This is the most comprehensive collection of first world problems I've ever seen. And hilariously accurate :)

This is really cool! Also, my girlfriend suggested it would be nice if she can login and be on the same flight so we can fly home together.

thank you! I had actually made that feature and then removed it to simplify. I will consider adding it back :-)

Earlier quoted context omitted.

That's... why? I can understand slow games like EuroTruck or Farming Sim. But what's the point of this?

Nonwithstanding the human fascination with simulation and simulacra, Airplanes and Air Travel represent a fascinating cultural touchpoint with much insight and depth to plumb depending on what aspects you simulate. For example, think of a history class charting flight from the Wright Brothers, through the Golden Age of Aviation, right to the present day. Even showing the drastic differences pre and post 9/11 by refer…

A game where you're narcoleptic and keep falling asleep at random unannounced times. While taking a flight from A to B, you wake up at different times entirely, on the same (or an equivalent) flight, seeing whatever was going on back then. Sometimes it's a flight with the Wright Brothers, sometimes you're flying during WWII, and sometimes you might just be on the plane heading towards the twin towers (right as you wake up back on your own original flight). Maybe even some mini-games where you might have the chance to foil a hijacking in progress, or maybe you need to be "the doctor on the plane", or maybe you wake up as the guy that's carrying the crying baby. You never know when, where, or who you'll wake up as.
