A technical demonstration of realistic liquid simulation for Minecraft, Liquid Cubed is a WIP project where you can build dams, pump water, drain lakes, and otherwise experiment with the liquid system within the building area. ------- The algorithm used for the liquid simulation was developed over two years by in a modified version of Infiniminer. After Minecraft's wild success, we thought it was about time we built a standalone "proof-of-concept" in the hope that the algorithm could be integrated within Minecraft, but unfortunately more work will have to be done before this can become a reality.

Improved performance, distance fogging, bug fixes and more in this update!

Posted by on


RANGES
The rendering engine has been improved again to give us control of the range in which water rendering is updated. Another one of those "big steps" towards infinite!

For now we're using a basic "fog" to simply stop drawing chunks in the distance to improve performance, but this is only a stand-in.


FOG IT UP
Press "F" to cycle through the different fog ranges. For now, this is an easy way to vastly improve the framerate in the larger courses.

We've also got a good idea on how to do a volumetric fog shader separately for the water. This wouldn't gain any performance or anything, but it'll look cool... and help to see the depth of the water better.


TOOL TIME
We didn't have time to implement new tools (the requested top priority "fun" feature) but we did go over which tools we'll add and how the interface would change to accommodate them.

Redoing the interface for tools could take some time if we were to implement it 'fully', so we might do something a little more ad hoc in the meantime.


SEVERAL FIXES
We've added some more direct error messages for when a dependency is missing. This should help to diagnose why Liquid Cubed is crashing on startup for some people.

In addition, springs now create water above themselves, sponges no longer remove the wrong blocks nearby, and pumps can absorb water from springs that are directly adjacent.

Also, thanks goes to JRose for detecting and demonstrating a little "infinite water" bug we had with our pumps. His screenshots were spot-on and allowed us to rapidly resolve this issue. =D


PRIORITIZING FUN
Our focus is on improving the performance of the liquids -- not recreating Minecraft -- but there's still plenty of fun things we can add to Liquid Cubed.

Last time "more tools" were requested to be the top of the priority list, but we ran out of time before it could be implemented. The priority list was arranged in the following order:

A. More tools: (line, fill, rectangle, etc)
B. Improved liquid polygons: (smoother edges, dissolving particles, variable width waterfalls, etc)
C. HD visuals (specular & normal mapping, water reflection, distortion maps)
D. Re-designed interface/controls + higher resolution
E. Perlin noise terrain generation
F
. More blocks available (different colors, objects, etc)
G. Critters for the fluids (fish, sharks, crabs, ducks, etc)
H. walking/swimming/collision mode (Ability to switch between free flight and walking/swimming)

How would you arrange the priority list for "fun" features for Liquid Cubed?

I suggest the UI should be very simplistic and basic in terms of similarity to Windows 98 style. Nice job team. The priority list is fine as it is. More tools and more parts = more fun.

Sounds great. I think the list is fine, if I would change anything, it would be switching C with F, random terrain generator would be an awesome thing to have.

Instead, custom blocks would be prefered.

We'd agree, an interface suited for rapid creation (without being too technical) would probably be best. Great to hear you're in support of this!

No offense, but that game is clearly a somewhat copy of Minecraft, created by Markuss Persson

No offense, but you should read the summary of what this is at the top of the page. It seems this project is an attempt to improve the water dynamics, control of said water, and what it contains (ie.fish) for Minecraft. Meaning they hope their work will become a part of Minecraft to make it better.

LC is getting better and better.
