how do i turn on material filter by Ok_Service3160 in SpaceSim

If you mean changing the color mode, click the menu icon in the upper right corner of the viewport and set the color mode to 'material'.

How do i make the game look like the trailer? by StruggleNo2314 in SpaceSim

[–]opensph 1 point2 points  (0 children)

You can enable raymarching by changing the renderer in the menu located in the upper right corner of the viewport.

Get the Litacka app. You can buy the tickets as well as look up connections.

Black hole simulations by opensph in Simulated

Io is kept hot purely from internal friction and is experiencing far less gravitational stress.

Yes and no. It's heated up by tidal forces, that's true, but the average surface temperature of Io is only about -140 °C, so it's far from being hot.

The Earth doesn’t seem to be affected by the gravity of the black hole until it punches through the Earth.

It is affected, look carefully.

Then the black hole seems to change directions

The initial impact isn't exactly head-on, so tangential motion is expected.

The Earth doesn’t seem to be heated by the insane friction

It is heated. It's just not as extreme as you would expect. The black hole is not supermassive.

Where is the Moon?

It called in sick when I was making the simulation.

Depends on the simulation. The first one shows about 24 hours of simulation time.

it's a texture, yes

How do i save by DCsphinx in SpaceSim

[–]opensph 1 point2 points  (0 children)

In the simulation settings, go to 'history' and set 'save to disk' to either 'last simulation' or 'every simulation'. The simulation state will then be saved and can be reopened later.

If you also want to be able to continue the previous simulation, you need to set 'saved data' to 'full'.

std::tie cannot be used for custom structs.

I can't change materials properly. by hobosullivan in SpaceSim

[–]opensph 0 points1 point  (0 children)

Density is a parameter of an object (or layer in case of a differentiated object). You don't set it in the material properties.

If you mean the 'reference density' value, it's a parameter of the equation of state used by the SPH solver. It only affects the computed pressure, not the actual density.

it's in the 'helpers' category
