Fluid Water Simulation 3

New version of liquid simulation sandbox, you can create water, oil and foam, add pipes and sewers, draw walls and air emitters. New Grid function is added for drawing straight lines. Maximum number of particles (drops) is 8000.
It is based on smoothed particle hydrodynamics (SPH) - Langrangian method of fluid simulation. This simulation is quite process intense, sometimes it helps when you close other tabs in a browser.

New features:
- Added pipes and sewers for never-ending complex water system.
- Grid for straight lines.
- Max number of particles is now 8000.
- and... Ducks! You can play with 3 ducks :).

Here you can find older version - Fluid Water Simulation 2 and more experiments.

Tools:

Water - create water
Oil - create oil, lighter and higher viscosity than water
Foam - create foam, very light with high viscosity
P - Pipe - create water, oil or foam pipe
Sewer - create sewer, if you want to remove liquid
Mix - use for mixing liquids [alt. right mousebutton]
Remove - removes liquid, pipes, sewers, ducks

Wall - draw colission Walls
Delete W. - delete colission Walls

Air - draw Air Emitter (visible when edited)
Delete A. - delete Air Emitter (visible when edited)

Duck - add three yellow ducks

Grid - use Grid for drawing straight lines
[Particle Bar] - shows number of particles on scene
Limit - 30fps limit [on|off]
Del All Liquid - delete all liquid
Delete Scene - clear everything

Particle bar shows a number of particles on scene. Maximum is 8000 and default framerate is 40fps. If the framerate is lower than 35fps bar is greyed out and if the framerate is lower than 30fps you can't create more particles. You can turn on/off this feature with Limit button.
(for example on Core2Duo E8200 2.6GHz you can create 8000 particles, Core2Duo P8400 2.2GHz - 3500 particles, Pentium4 2.8GHz - 2000 particles at 30fps)

Troubleshoot help:

The applet is tested and working with Firefox, Opera and Internet Exporer with Java plugin. Found out that applet is not working with Chrome on some systems.

If applet is not running in a browser window try to:

1. reload page and wait a while, if it doesn't help,
2. delete browsers cache and restart browser, if this doesn't help,
3. download latest Java from here for windows or manually from here for all operating systems and reload page. Test if you have installed latest Java plugin here.
4. use Firefox or Opera instead of Internet Exporer (you have to allow active content in IE).
