Crysis Realtime Water Physics Pt 3

[manword1]

that was scary

yeah i know but realy that was scary ^^

[Play671]

How you make that?

[imalwayswatchingu00]

What sort of CPU would be need to render fluid in realtime, with about 1 million particles :)

[clumptrooper123]

omg im sorry but that looks terrible and fake

[HeyItsASquirrel]

holy shit man it looks so much better really good update

[CreatureFearing]

sweet fps bro. 

[soderholm13]

ATTENTION STALKERS, AN EMISSION IS APROACHING! GET TO COVER, NOW!

[T0mmyboy100]

That looks so FUN!

DX

[SchofeildServers]

Notis that your lagging like shit (anything below 20FPS is SHIT.)

[anderska1]

if you are not stupid, you can see that he records

[slimbullet96]

its a tsunami

[chipaputalaguea]

run is the fury of god =O

[rebel9568]

how do you make a tidal wave, just shoot a nuke in water

[jimmypagek26]

i love the particle physics but i dont see water

[dapapeyu]

you almost got own3d by that tree!

[MexicanLeaderTaco]

can i connect a controller on my pc and play crysis

i just got into pc gaming and im still used to analogs

[Lovick001]

Yeah, if it is a usb controller, there's a gamepad option menu for setting it up in Crysis.

[Tohinho1995]

no. Only 360 controller

[Lovick001]

And have you tested this "fact?" I'll believe you if have prove.

[Tohinho1995]

no, that's because of i only have a normal usb controller and it stays grey. I searched it in google and many other users have the same problem. But at least the 360 controller fits good in hand ^^

[951258tike22]

i use a ps3 controller, im pretty sure any gamepad will work

[maning04]

of course but pc controllers cost way expensive you know?

: )

[Vorkosky]

Holy #@*£ a tree im gona die! more like holy #@*$3$ im getting tired

[jimmypagek26]

notice how there is no framerate

[conizme1]

Lol

[PlayerOblivion]

haha XD

[rykuthemaster]

Tsunami

[spartan9000001]

just wondering ere wat sorta hardware specs we talkin bout ere to be able to pull that off?

[tornadomad]

good ones

[jared33647]

do a tidal wave in the ocean with some enemy boats

[dirtfighter]

now that was awesome!! LOL

[Mavrik347]

test sorry :P

[CRYSIS132]

thats not impossible i have don it on crysis its so easy.

[snaker1237]

how did u make it like that ?

[openracing]

LOL. Who negatively rated my comment? I have been a games developer for years; if you think you know better, I'd be happy to hear an explanation.

Why is it impossible? Because it takes hours to render, that's why. In Blender, for example, it takes on average 50 hours to bake an accurate fluid simulation.

Particles/shaders do not "simulate" water! Look carefully at 0:16. You can clearly see the flat blue textures! -.-

Search "Fluid Simulation" in Wikipedia for the true method.

[surferson]

Technically, Its not impossible. People are now working on games harder than ever. Its been advancing alot. Yes, It would take awhile, but eventually, Theyll make it if well buy it. Ya know?

[openracing]

You're right. I phrased it wrong. I meant it would be impossible [at the moment] for Crysis to have implemented such a feature. It can be done with an 8800 Nvidia using DX10, but it's still rather crude and inefficient to be used in games. In the future realtime fluid simulation will be normal, but at the moment everything is done using pseudo-techniques such as particles and shaders. ;)

[surferson]

We gotta start somewhere.

[XenTheKiller]

Does a game developer use the LOL word ??? I dont think so..... Dont reply....

[LukeMadDogX]

He's right! I'm pretty sure I read that game devs only say ROFL. Don't listen to what this guy is saying!

[XenTheKiller]

Im joking.....

[dutubeuser]

can you write how do you make this please? and what particle effects you used? thx

[openracing]

That's not realtime water simulation. Realtime water simulation is impossible. The true method takes hours to "bake". What you see here is the emission of many particles with blue textures, basically.

[crazybro191]

True.

[DDA1220]

please, tell me how it is impossible.

[Genome66]

It is not impossible it just requires extremely powerfull hardware. This is done using a particle effects where each particle has collision physics. The only thing that stop this being impossible for modern hardware, is that the particles don't collide with each other

[changestyleman]

@Genome66 this was the past men.... :P my water it's better!!!! :PPPPP

[DeadCatStudios]

@openracing

This IS real time. -.- The water as Genome said is that the water particles don't react with each other.

[Dazbme]

@openracing go, search nvidia physx fluid and click the first result, that shit is real time

[Galient5]

@openracing you ever seen nvidia's physx demos? thats real time fluid rendering

[evillllll1]

@openracing PhysX, Dumbass.

[DeathScytheBR]

@openracing 3 years later (now) it is possible. See the "From Dust" game tech demo vids.

[Raptorhide]

@openracing true water physics is impossible to this date yes, but many companies use small balls to simulate water, this works rather well, just not 100%, although you wouldn't see the difference.

[sickgreg]

tsunami

[kevaughanshiu]

umm.... its good so far. but you know, touches can be made XD

keep it up i guess

[FacToRx93]

HOLY PWNTAGE LOL COOl!

[135135135135135]

Good job!

Now what would really kickass is a tsunami decimating a bunch of huts.

[feenux09]

try using capture_frames to see it how it should be :P at 30fps

[ArmySupa]

put some houses in fornt of the wave haha

[zapbolt]

Niiice dude!

[34minutes]

You should render some videos using capture_frames so we can see the full wave without the stutter.

[Genome66]

I want to do this all in Realtime, no precomputation...

[34minutes]

Yeah, we know it's impressive. But still you're getting 2-3fps on that video, and we can't see the water in it's true smooth motion glory.

[Genome66]

Yeh I'm going to optimize the particle effect. You get the idea though.

[jackoneill45]

Damn man, thats crazy! I gotta add something like this in one of my maps. Nice job on getting water physics, is it done with simple collision or simple physics in particles editor, or something different?

[Genome66]

You see the collision of the particles, but the physics is invisible and is behind what you to make the water act like real.

[roswell34]

i see no box throwing

[Genome66]

Will do

[Flyinguberleetpig]

Holy shit man, that's epic.

If you could scramble up a tutorial for this I'd be forever grateful.
