I've managed to manipulate the perspective, size and viscosity of the NVidia Fluids CUDA sample code:
http://developer.download.nvidia.com/compute/cuda/sdk/website/Physically-Based_Simulation.html
It is now displayed in a 3D perspective and similar size to the terrain that is below it. The colour has been changed and the viscosity has been reduced to feel more like water.
Next I will take a look at changing the individual point colour values in another CUDA kernel function to try to make the colour more realistic. Also, work needs to be done to figure out how to properly display the terrain within the water (depth issues).
