Hydraulic Terrain Deformation Preview

Here's a quick couple of screenshots and videos of my hydraulic terrain deformation project I'm working on. So far I have water flowing over arbitrary terrain, and pretty much all the underlying code and systems necessary to start deforming the terrain via hydraulic erosion. The simulation runs in real-time entirely on the GPU, i.e. no data is transferred between the CPU and GPU while it's running - all data calculations are done with GPGPU methods.

I'll give a more thorough explanation when I have more time (probably when I'm done with the project) and I'll probably post the source code as well.

GPU FTL....Again

Having one GPU fail on you is rare as it is, but having the second just-replaced-less-than-a-month-ago GPU fail also??? What rotten luck I must have. Either that, or the GPU seriously disagrees with my shader code and is willing to destroy itself so that it doesn't have to be subjected to my cruel instructions anymore. I think it's a toss-up.

Once again I had a replacement shipped out under warranty, and again the response was prompt, which made the loss of the GPU about as painless as it could be. I take a small bit of comfort in knowing that when this GPU fails it'll only take a couple days to get replaced.
