Something to make colisions perfect
« on: September 20, 2014, 10:47:42 AM »
Colisions in US² are just awesome. But there is something missing. It's shock heating. Shock heating is the heating (water evaporation, lava...) of the planet as the shockwave from the impact passes by. It would be awesome to have a giant showckawe burning everything while the other side of the planet is still normal but doomed...
Is shock heating going to be implemented ?

Uh, there are shockwaves and initial testing with shock heating in alpha 11. Theres still some issues with the heat simulation though.

In a not-so-close version, I hope there will be local temperature instead of planet temperature (so that the planet don't heat up in one go)

SPH for local heating.

SPH is the Jesus of US2

SPH=Awesome !
I hope it get implemented soon....

SPH will make US2 much more realistic

Its like adding physics to the planets, so they can be deformed, it will be the most amazing thing ever.

At least this is what i know about SPH

What is SPH?


I have a couple of videos here
https://www.youtube.com/user/GreenleafDevelopment


really simple explanation would be: is is a way to numerically solve the physical equations describing a material, commonly a fluid. Lots of other methods exist for this, but SPH is different in that it models the material by a set of moving points where most other methods model movement inside a previously defined grid. This is a good thing when the material is going to break apart and when the material is a small thing moving in a huge space.


http://en.wikipedia.org/wiki/Smoothed-particle_hydrodynamics


I would like to point out that there is really nothing special about SmoothedParticleHydrodynamics as opposed to FiniteVolumeMethod, FiniteElementMethod, FiniteDifferenceMethod, LatticeBoltzmanMethod etc etc. Its just one of many methods to take the mathematical description of the physics of a material and make it solvable on a computer (or with pen and paper if you have the time). It is just slightly more optimal for large deformation and fragmentation.

Isn't that already in US2? I can see a distinct dent in a planet I threw a small moon at, one that seems more than just a shader trick.

That's just heightmap denting. With SPH, you will be able to rip apart planets with gravity, simulate the Big Splash, etc.
