That was a 2D simulation - the latest project is a 3D fluid simulation. You can see the result in the video below but the important point is that the code that produces the video runs at rates that are fast enough to be interactive on a GeForce GTS 450 - which is not a top of the range GPU card.
where you will also find descriptions of how the change from 2D to 3D was made. Unzip the download and in the unzip directory create a new folder called Build. Then type:
cmake .. -G "Visual Studio 10"
When the make is complete you can then load the project specified by Fluid3D.sln or simply type Fluid3D.sln at the command prompt. When you see the project in Visual Studio set Fluid3D to be the startup project and run to look at and play with the code.
I have to add that my previously very satisfactory graphics card only managed to run the simulation at around 1 or 2 frames per second which made it almost non-interactive. If nothing else this is a good test of a graphics card - time for an upgrade in my case.
The Internet of Things is an emerging technology which makes it both topical and hard to pin down. You'll obtain completely different viewpoints according to which MOOC you choose. So it's worth surve [ ... ]
