Helo,
I'm working on a program doing fluid animations for POVRay. I focused my
last coding on the simulation of a fluid environement which is moving. I
share here my very first result : a small animation of the expension of a
cylinder in a water tank.
The video is MPEG1 encoded.
Regards,
Fidos.

Looks like the scenes you see in nature videos of boiling/bubbling mud
near hot springs. Nice work, I'm really liking these fluid anims!!

I really like your fluid animations. How do you set up the environment? Is
it currently hardcoded, and how flexible is it?
Another thing you might want to try is create a "final version"-kind of
animation to show off, like something with realistic water material
(fresnel, reflection, refraction, photons). Would make the results more
comparable with real-life effects.
I think that a lot of Povers have an interest in fluid animations,
especially if they can be tied into the scene-files easily (e.g. via a patch
directly into POV-Ray, or by calling a small executable inbetween frames).
So, are you planning on releasing it, making it useable for the wide public?

Thank you. The environment is defined by a serie of dfd files : an ini file
loaded at the start of the simulation defines the dfd filenames for some
key frames. For the frames between the key frames, the simulator
interpolates. For the build of the dfd file serie, I use a program which
generates it from a script file.

It's something I plan but I know it took a lot of time and some talent. I
made some tests with transparency but the rendering times increase too much
and I prefered to use not transparent material. In any case, I agree with
you, fluid animation is interesting only if we succeed to render as close
as possible to the reality.

I already made change in the simulator in order to prepare a release for the
POV-Ray community, but I have still a lot of parameter hardcoded in the
program. Moreover, the program is moving a lot and I want to reach a level
of functionnality before to release. I'm currently working on the
water/object interaction. The simulation of this post show object -> water
interaction, for the water -> object interaction, it asks for the use of a
mechanical simulator. For the moment, I plan to use MegaPOV and the MechSim
patch. It results in the necessity to use MegaPOV for the use of my
simulator.
