the last vid has surface tension as well as better viscosity and less compression.

edit: you can download the last vid now here

The demo is very cool, but the water and oil spawn to slowly, and I'm pretty sure it's not lag. Is there any way you can speed that up?

yeah I can speed it up but then sometimes the particles freak out if they spawn in exactly the same place but this isnt a game yet so the spawn speed of the particles is the least of my worries...

Oh, I understand. So you're planning on turning it into a game?
Sounds like fun, and good luck!

Wow, not bad! I was able to simulate 5000 particles without lag. Did you use any additional libraries to BlitzMax or did you use the standart graphics engine?

No additional libs, straight up blitzmax. I use the standard graphics rendering engine (max2d) but I plan to switch to one that has shader support if I can someday soon.
