During GTC 2014, Nvidia has showcased tha latest version of Flameworks; a system for generating fire, smoke and explosion effects for games. Flameworks combines a state-of-the-art grid-based fluid simulator with an efficient volume rendering engine, and this latest tech demo is impressive (to say the least). This is by far the best ‘fire and smoke’ tech demo, surpassing even the one for Deep Down that Capcom introduced a while back. According to Nvidia, this is real-time volumetric fire simulation running on GeForce Titan Z and packs 32 million voxels. Enjoy!

Still, the PC platform won him over consoles. That was mainly due to 3DFX and its iconic dedicated 3D accelerator graphics card, Voodoo 2.

pointless having an entire titan card used just for the fire. This demo is unrealistic, you can have millions of interactive simulated particles if you have quad sli but what is the point ? As with flex, it will take at least 4-5 years to have something similar in games,
well actually they didnt say it TOOK one titanz to do this demo, just that it was running on a titanz which is what NVIDIA always does with any demo(running on their latest and greatest). Instead i wish they run it on maybe ordinary freaking cards that us mere mortals have =_=.
ok sure but it does look like it is running below 30fps some of the time. Or at least i perceive it that way,,,
These sorts of effects you’ll only find in proper CGI apps like Maya, if you want an “ordinary” demo for cards then download the tech demos from NVIDIA. The fact that one mainsteam card can do it at all in realtime is staggering.
You don’t understand the fanboy logic, if even one PC is capable of this, that’s “PC gaming” now. Despite the fact most PCs on Steam are running intel integrated graphics and the most popular GPUs are $100-150 entry level or mid range.
Wrong. 51.94% use NVIDIA GPUs and 31.03% use AMD (ATI). A mere 16.66% use Intel GPUs which is far from “most PCs on Steam are running intel integrated graphics”. Did you even bother to look at the Steam Hardware & Software Survey stats? Here’s a link if you don’t believe me: http://store.steampowered.com/hwsurvey/

This is very impressive – fluid dynamics take a shitload of processing, and this is doing it on the fly, on ONE graphics card.
We’re probably another 10 years away from a perfect in-game Bolrog, but progress needs to start somewhere…
The volumetric effects in Star Citizen are calculated then highly optimized – what Nvidia is showcasing here is dynamic, volumetric fluid simulation. It is VERY computationally expensive. I used to run fluid dynamics on my computer – a 20 second splash of water took a very long time to calculate.
32 million voxels…
Don’t know exactly what it means in polygons/second, or x gigabytes of bandwidth, etc…
To have an idea of what that truly represents…
In all cases, I understood that this is the kind of techs that will sell 700$ cards to people, year after year 🙂
Slowly, PC graphics on games will get closer to Pixar stuff. So I ask the question: in 4 or 5 years, if a PC and a quad 20x titan card can output stuff close to Pixar, WHAT crazy stuff will Pixar/etc be doing?
Honestly, when I see movies, today, where it is impossible to distinguish true places from cgi-made places, trees, forests, almost everything, I believe in less than 10 years, there will be CGI actors, capable of moving, all possible face muscles when talking, etc etc.
Studios will then ‘rent’ Steve, which is a 3d model of a funny guy, that Z company has created and made movies with, making him very popular. Instead of having a brad Pitt, they will rent a 3d model, that will cost x $$$, based on how many frames or seconds he will appear in the movie.
There are already many great 3d faces out there. Pantha ray one looked amazing.
I am sure if I show the sorcerer demo from Quantic dreams to 1000 people, from 6 to +70 yo, most will think the guy is real.
For the curious, it’s here:

Impressive tech. Nvidia has done it again!
Wow , looks incredible . Upcoming games from CDPR may support this in the distant future just like fur simulation etc .
That looks amazing but it doesn’t make it complex. Remember the film Final Fantasy Spirits Within? That has 2D hand painted background so save on render time.
Read this by Nvidia please, a lot of you are just guessing. NVIDIA FlameWorks is a system for generating cinematic fire, smoke and explosion effects for games. It combines a state-of-the art grid-based fluid simulator with an efficient volume rendering engine.
The simulator uses a highly optimized solver which enables the simulation of high resolution grids in real-time. It supports collisions with standard primitives and includes a combustion
model for generating flame effects. The system is highly customizable and supports user defined emitters,forcefields and collision objects.
The GTC 2014 fire demo demonstrates the cinematic quality of fire/smoke together with ray marched reflections on the ground as well as interaction with a sphere. The demo uses a 512x256x256 voxel grid, meaning that 32M voxels are updated every frame and runs at more than 30fps on a GeForce 780TI.
For actual game use cases the voxel grid size is scalable and can be used with lower resolutions as well.
No Particles were used in the making of the demo.
