will there be swirling smoke effects?

[hannibal]

i see that there is dirt kick up when the helicopter is near the ground..

 

how about when the helicopter passes through a blown up target? will there be swirling smoke....

 

2:15 shows some swirling smoke ...

[crazysundog]

Yeah, I'd like to see the effects of some smoke through blade tip vortices!!

[Allo]

That was freeky. The music that is.:suspect:

And the guys SPRAYING with their rifles.:lol:

I must agree. The swirling smoke was way cool. Would be cool if it was added in a future patch for BS. It's too late to add it for release because there is only 87 days left in 2008.:music_whistling: But who's counting?:bounce:

We can only hope.:prop:

what movie is this from?

[DTWD]

Although a lovely effect I don't think it's possible with todays technology and the game to still be running at 30+ fps.

 

Changing the direction of the smoke is one thing, but having it get caught in the vortices is asking a bit much at the moment I think. Your getting into the realms of particle simulation and doing that on the fly to that extent will just kill any modern day uber PC.

Scenes from a russian movie from 1993. (http://ru.wikipedia.org/wiki/Чёрная_акула_(фильм))

If my mind isnt failing me i think WIC (World In Conflict) has that effect when using DX10. I think i saw it in some spec list and then tested. I might have dreamed it too. :)

 

Found it (check down middle of the page): http://hothardware.com/articles/The_State_of_DirectX_10__Image_Quality__Performance/Default.aspx?page=11

 

"soft particles in World in Conflict also exist in-game, which means that particles are effected by other in-game objects. For example, in DX9, if a helicopter flew through a plume of smoke, it would simply go directly through the smoke effect. That same scenario would play out much more realistically in DX10 since soft particles would be effected by the presence of the helicopter, resulting in the smoke being dispersed by the helicopter's passing"

 

And yes, it looks bloody fantastic. Its a RTS though. Might eat a huge quantity of CPU if added in a sim. But in the future... Next engine... :)

That's a great game, if I remember correctly I was running it in DX9 due to "problems" with DX10...the problems being frame rates through the floor, it had issues in DX9 to be honest.

 

But that aside DCS is going to be DX9 complient so ED most likely need to impliment some DX10 code reworkings before we can even see if it will kill the sim.

 

I think we are about two years (or two generations) away from GPUs being powerfull enough to cope with effects like that in there stride, the last thing we want is to be skimming through some valleys to be lagged out by some evil passing cloud of smoke.

Dont know if it was the patch, but i played it with latest patch in DX10 and my game flowed very good with most things on max. Looked amazing. But yeah, i think that particle effect together with a sim like BS will be too much at this moment. Wind AND heli props affecting smoke pillars here and there. Well i dont know coding, but i guess it would need a lot of power from the cpu.

I know that the upcoming WW1 flight sim "Rise of Flight" (aka Knights of the Sky) had a video showing this effect when a WW1 fighter flew through or past a smoke column.

I hope it's not using the Flaming Cliffs engine. That needs a major overhaul, the code seems to be very inefficient, for starters. There's an unnecessary FPS hit for expanding smoke. Hopefully the tree generation gets a facelift too. Also unnecessarily bulky.

[DTWD]

I think they are, but it's modified and then there is a whole new engine somewhere down the line...but I get the impression it's WWWWAAAAAAAAAYYYYYY down the line.

 

The main problem with the FC engine is that it's predominantly CPU based with very little done on the GPU (and it's DX 8. The improved engine uses DX9 (so we are told) which will hopefully mean quite a bit more is put onto the GPU.

Particle simulations are already in the game, albeit not as advanced. The vortex ring phenomenon is implemented in the game, although i do not know if possible, one could probably make the smoke particles be effected by the vortex ring. I think this is something that is definately coming sooner or later. Who knows whats in stores with the new engine when it will support multitasking and parallelisation. :)

[crazysundog]

Is this in the Wish List yet?

 

Anyway, cant wait for the day when this is possible with the DCS modules, I'll probably spend hours and hours creating smoke trails!

Yeah I think the engine isn't too great. I remember when I cranked the settings and ran it with a quad core and an 8800GTX and hoped it would be perfect and it just wasn't. Which made me think the engine is a bit messy.

 

I think they will get it right with DCS though. Someone says in the wishlist that they plan to upgrade the engine in the future, so I bet it will be really good then.

You meant this, right?: http://www.youtube.com/watch?v=cnwz3WQfuWM&feature=related

That was to demonstrate the fluid physics only, no smoke, thought.;)

[DTWD]

Fluid and air are very similar when it comes to rendering/modelling it's mainly down viscosity etc.

Isn't air regarded as fluid in engineering?

Yes, but imagine visualizing thousends or millions of particles with this physics model...

[DTWD]

Oh I know, hence I was saying earlier it's a bit off yet before we will be seeing it in our soon to be born DCS.
