How big can be 3D map?

category: code [glöplog]
How big can be 3D map in multiplayer game or 3D open world engine?
I mean playable on normal HW not supercomputer...
And I dont mean procedural generated like No Mans Sky.

Just Cause 3 -
1000 km2

Fuel -
14 400km2

Guild Wars Nightfall -
38850 km2

Are there any bigger games?
Do you have your own 3D engine with huge map?

I can imagine "Wolrdmo" - world demo... New demo category... Haha.

fuel is proceduraly generated

And best, winner will be smaller code huge map... How big can be for example 512mb map...

Our world map in our game consists of 48 * 400km2 maps so I guess we win.

Kerbal space program has multiple full planets. Kerbin alone has a surface area of 4.5 × 10^12 m^2.

But your question, of course, is silly. Maps can be arbitrarily large if they have little or no detail. They can be very small and crammed full of manually created detail items. They can be procedually generated, they can be semi-procedual...

The correct answer to your question is: in 512MB you can store a maximum of 512MB of kolmogorov-complexity map data. Theoretically.

Just upscale and subdivide.

So remove fuel...

I mean Worldmo should look like:

There will be demo with strict camera fly by.
Or scener will use wasd plus mouse to see Worldmo...
Or something like that.

Pattern recognition, anyone? :)

@Gargaj-"Our world map in our game consists of 48 * 400km2 maps so I guess we win."
Name of title? Where can I buy it? Steam? So 19 200km2 total? Thats pretty huge!
Thats almost size of Slovenia!

Just wait until a topic about Bane shows up.

It's still gotta be procedural though? You can create small maps by hand and generate a huge map including the ones you've created.

if you use Euclideon's unlimited detail technology, the map size can be infinite, both in map area as in small details. you can have a 1:1 scale of the earth including every grain of sand! it's incredible but true!
Rendered a quad yesterday... sidelength was one lightyear.

But if your map is one light year in size, is it really real-time rendering if your renderer takes less than a year to render it completely?

You can just LOD it.

There is also Outerra Engine (whole Earth)...

But it is more like VR simulation engine than game engine...

"Outerra is a unique 3D rendering engine, a world rendering engine capable to seamlessly render whole planets from space down to the surface. It can use arbitrary/varying resolution of elevation data that it further dynamically refines using fractal algorithms. The fractals try to mimic natural processes, generating fine, believable terrain with high resolution. The world is also being dynamically textured and populated with vegetation using predefined land type material sets and the computed terrain attributes."

a 3d map can be "infinitely" big. depends how you wrap 64 bit. and ofc you gotta generate it procedurally. what the fuck. you want people to model the fucking dirt on the map. this works only irl. and minecraft. and realdumbness simulators maybe.

that metaverse thing? or the supercomputer?

I'd say 42, maybe more.

I like procedural. I like old Daggerfall. No matter if it looks empty and boring. I go there and sit on top of empty quad, meditating.

The maximum size of a 3D map depends on your monitor size; it needs to fit entirely inside your monitor. The games listed above cheat by making everything tiny and scaling it up, making it just appear bigger. In reality they have really small maps!

For flat-screen monitors, DirectX and/or the OpenGL driver automatically flattens your projection matrix to account for the real flatness of the screen. The reason why they are not entirely flat is that they still need a little bit of z-buffer precision.

some focus on girth when they feel their map is too small.
but i would also go with the 42, maybe more statement.

No more than 2500 m^2... Otherwise it tooks too long to mow the lawn...

Big! Very big! Because... What if...?
