NVIDIA has updated the PhysX fluid Demo to 1.0.1.3. The demo is basically a demo to show off PhysX based water or the more technical term, Smooth Particle Hydrodynamics (SPH). This is a great little program( less than 20MB) that can be used to quickly test out a new PhysX setup such as a dedicated PhysX card or a Hybrid ATI and NVIDIA PhysX setup. Using a simple toggle you can easily switch between Hardware(GPU) and Software(CPU) PhysX to not only to see if your dedicated PhysX card is working but to also see how a GPU helps improves PhysX performance. When I am installing a new PhysX setup I always install this program along with PhysX FluidMark to make sure everything is up and running properly.
You can download the demo here from the NVIDIA Power Pack page and in the event that it is not working PhysXinfo.com always has the latest PhysX Files. You can download it here.
From NVIDIA:
Fluids: Technology Demo
The primary purpose of the NVIDIA® PhysX™ technology Fluid Demo is to illustrate Smooth Particle Hydrodynamics (SPH). The demo contains two different scenes, the Outdoor and the Logo Scene.
Outdoor Scene
This scene showcases SPH fluid flooding an outdoor area. As soon as the demo is started, a flood occurs and interacts with a stack of rigid bodies. Switch from dark water to clear water, to oil, or just show the real nature of fluids: spheres.
New Updates to 1.0.1.3:
Updates in this release:
1. Allocate only 64MB of VRAM heap instead of 128MB
2. Adjusted text output to not conflict with the PhysX Visual Indicator
3. Added option to toggle the display of all text (in screen space) on/off.
If you have never seen this demo before the below video from NVIDIA shows the demo in action.
A cool new water tech demo has been uploaded to the NVIDIA CUDA channel on YouTube. The demo shows some realistic PhysX based water simulation being run on the GF100(Fermi). According to PhysXinfo.com this demo is showing off “Smoothed Particle Hydrodynamics (SPH) PhysX Fluid simulation demo, running on GF100 GPU”. Check it out below, we also embedded an older version of a PhysX fluids demo of Next Generation GPU Fluids according to the YouTube channel it is “128 thousand particles simulated and rendered in real-time on the GPU. SPH fluid simulation with surface tension effects. As demonstrated at the NVIDIA GPU Technology Conference 2009″
Pretty awesome stuff, imagine when games start to use realistic physics based water like this.
I am pleased to announce that GamePhys will soon have a dedicated test and benchmarking system for the site. This was a project I have been meaning to do since I started the site back in 2009 but never got around to it. The first phase of this project really got started this past BlackRead More
On Friday at GDC 2012, Aron Zoellner and Kevin Newkirk of NVIDIA presented a really nice hour long session titled Enhancing Games with APEX PhysX (Clothing, Destruction, Turbulence). In this presentation they went over the features of APEX PhysX Cloth, Destruction, and Turbulence which we have seen implemented in recent games like Mafia II andRead More
We have been hearing rumors for the past year now that AMD GPU’s will be used in the next generation consoles however, aside from reports that the Xbox would use a Fusion variant of Bulldozer, we have not been hearing to much about the actual CPU that may be used. Now SemiAccurate claims that theRead More
Zombiethatatehimself creator of the Awesome Apex PhysX Impact Damage Demonstration and Apex PhysX Impact Damage Demonstration With Stucco/plaster, and the Apex PhysX Voronoi Fracture and Destruction Demonstration has made another cool Apex PhysX demonstration with the Unreal Development Kit. This time a similar to the Voronoi Fracture and destruction demonstration but with some cool plasterRead More
Some nice news from Havok as they have announced that they have entered into a “worldwide license agreement with Nintendo Co., Ltd., to make Havok Physics and Havok Animation available to studios around the world developing on Nintendo’s Wii U™ platform” Hopefully we will see some cool games implement Havok Physics and destruction. The WiiRead More
F1nalspace has made a pretty cool PhysX SPH fluids sandbox you can download and play with showing off some awesome PhysX based SPH(smoothed particle hydrodynamics). Check it out below. I made a fluid simulation in C++ with several customizable scenarios using PhysX SDK 3.0.2 rendered with OpenGL. Fluid rendering is done using a technique calledRead More
I just wanted to post these cool UDK PhysX videos I came across on YouTube. UDK wood fracture from 19minimin91 UDK/Apex Destructible Level Test from lankeytom UDK Physics Fun by GrinchPa
Now this is exciting news, Epic Games has announced in their GDC 2012 press release that they will be showcasing Unreal Engine 4 behind closed doors at GDC 2012. Last year at GDC 2011 we saw the Samaritan demo which was jaw dropping graphics wise but did not showcase much physics, at least destruction wise.Read More
NVIDIA has released new GeForce 295.73 WHQL Drivers which include PhysX 9.12.0209 System Software for improved compatibility and performance in Alice: Madness Returns and Batman: Arkham City. NVIDIA has posted an in-depth article about the improvements you can see in various games on the official Geforce website. There was also a PhysX System Software 9.12.0213Read More
This is old now but I never got around to posting about it back during CES 2012. During the CES 2012 Intel press conference, they showed a lot of information about the upcoming Ivy Bridge Ultrabook processor including a DX11 graphics demo showing off different games that the DX11 capable Ivy Bridge processor will beRead More
The NvidiaApexDeveloper YouTube page has uploaded a new video from the Art Gallery demo showing off some awesome Apex physics and destruction. Check it out below. For more footage of this demo in action check out the original Art Gallery Destruction Demo in UE3 using APEX Destruction with GRB’s video. Hopefully this demo becomes availableRead More
Charlie over at SemiAccurate has posted an interesting rumor that the upcoming NVIDIA Kepler, GK104 GPU will have optimizations for physics calculations in the form of dedicated PhysX hardware described as a “PhysX block.” It is unclear whether these optimizations will be actual dedicated PhysX hardware or just more shaders and other PhysX optimizations butRead More
