Hi,

I post a new fluid animation. The fluid simulation was done with a stand
alone program that I wrote in C, the rendering was done with POVRay.

It's a spherical glass filled with a liquid.

The simulation took around 18 hours on a P4 3.2 Ghz with 1 Go of RAM.

Fidos

PS : the video is MPEG1 encoded.

Impressive, how is this done?

Thanks.

The rendering is done in 2 steps.

First, I used a program that I wrote in C for the simulation of the liquid
surface. I use the level set method and the solving of the NS equations.
This method can give good results but is quite long (see for exemple
http://graphics.stanford.edu/~fedkiw/ for impressive animations). For each
frame, the program generate an isosurface file in the dfd format. For the
simulation, the environement is defined by a isosurface file (in dfd
format) which is loaded at the start of the program.

When I have all my frames simulated, I do the rendering in POVRay. I use
MagaPov 1.0 with the patch for density file :
