GPU Fluid Simulation with Volumetric Rendering

3D Fluid

A bare-bones but polished fluid simulator and volumetric renderer written in CUDA C/C++ in ~600 LOC.

There are videos!

The organization is based on Philip Rideout's 2D OpenGL simulator (http://prideout.net/blog/?p=58),
as well as George Corney's interactive WebGL demo (https://github.com/haxiomic/GPU-Fluid-Experiments)

TODO: More consolidation of simulation and state parameters. Temperature-based shading. Support for data types smaller than 4 byte floats.

Setup

In build.sh, check that the path to your cuda installation is correct. Then run build.sh to create an executable.

fat-clouds's Issues

Parameter presets?

Hi there. The videos you have rendered look great, but I am having a hard time adjusting the input parameters to get anywhere close to those runs. Would it be possible to add some of the parameters used in the videos to the Readme or another file?

FYI: I have parameterized the inputs in a fork to allow them to be passed via the command line, and I will be glad to send back those changes after I can confirm that they are working well with some presets.
