Good idea! I'll do that.

I dont know if Im going to be able to time-step this.
To get it FPS independant I need to understand whats going on,
and I no-longer do...

This code is actually setting every vertex back to zero every second frame.
It doesnt LOOK like it, and its thrown me a serious curve-ball..

EvilSOB, imho, you should go and rest this evening
Maybe some(well, "some" could be changed to "a lot of") beer with friends, or romantic evening with girlfriend

I cant, Im at work. Damned night-shift...

(If youve read the web-page from meh_master that he based his code on),
Im thinking of dumping its entire process, except the
vertices<-->neighbouring-vertices averaging filtering, and build up from that.
It seems (after playing a bit) to be the important part.

Germanunkol: this "averaging" filter bypasses the need for the complexities surrounding the usage of SIN-type functions.
Using SIN functionality drags it too close to a REAL water simulator. And that just gets too CPU hungry.

True. The reason i chose this method is because of its () simple method and speed compared to SIN based methods.
Turns out that it let us down on the 'simple' bit..

i would like to see w youtube demo.. anyone?

There will be youtube when all is finished. For now, you can have a play with the first demo.

Newton interface is finished. I won't post a download link just yet but i'll give the procedure on how add fluid dynamics to a newton level (that already has a buoyancy plane):

• In WED, place a .hmp right on top of the buoyancy plane. The .hmp MUST have a z coordinate of 0. If it doesn't, you must move the entire level so it does. Assign the 'fluid_action' action.
• If you do not have WED, just place it in script, and assign the 'fluid_action' action.
• in the fluid's action, assign the 'viscoscity'(0-100). You must also assign the 'surface_tension' (0-50) which specifies how deep an object has to be for the water to stop reacting to it.
• An entity pointer called 'waterent' must be set to the fluid .hmp .
• You must copy and paste a simple 10 lines of code (15 with particles) at the end of any object that you want the water to react to's action.
• Make the existing buoyancy plane invisible
• Run the main script!

It may sound quite complicated, but it's actually pretty simple.

I know this won't help to implement in your own projects yet, it's just to give an idea. I will release everything tomorrow (unless i go to a friends place) Promised!

The reason it took so long was that i was over complicating the action assigned to newton bodies. It was originally a complicated ~50 lines, but now is an easy-to-understand-even-for-newbies 10.

If I don't get any replies in my 'water particle bitmaps' thread, i won't add particles to this release.

@evilSOB: Making any progress? You haven't posted here for a couple of days..

Still zero progress, but I havent given up either.

[EDIT] Getting close though. I should have a result within hours.
Frame-rate independance - FIXED (WhooHoo ).
Viscosity - Progressing well.
Auto-viscosity Calculation - Unlikely to be hard.

Awesome! I hope you succeed!

Did you end up rewriting the code, or did you edit the existing program?
