Title: What do you want Universe Sandbox 3 to have?
Post by: mrt127 on February 12, 2012, 02:27:14 PM
Simple, what do you want guys?

I want:

Comets
Better Explosions
Better planet collisions
More Stars programmed  in such as Proxima Centuari, Rigil Kentaurus etc
Solar Flares
The Ability to age stars ( for instance I could age VY Canis Majoris 100 thousand years and watch it supernova and turn into a black hole!)

Well that's what I want.

1) A tool to measure distance in a straight line.

2) A solar system model that would represent the actual positions of our solar system for let us say 500 years. Not necessarily a simulation. Scripted would be nice as well, for a start.
 
3) Parameters for rings. It is quite strange to add rings with very slow speed to ultra fast spinning planets right now. I want to be able to accurately set their velocity AND their position around the planet.

4) Recently Dan posted a link on a site which provided data on satellites. A menu where you can add all the data of your choice to automatically reproduce satellites would be nice.

5) A tool/option for clockwise rotation. Not that it is any trouble putting a minus sign in front of the period as a workaround, it is just that you asked what we want.

if possible at all... nebula!
maybe realistic atmospheres with models as an option

Post by: Spaceguy888 on February 12, 2012, 06:22:26 PM
here are some thing I want added.

1. the big bang
2.instead of ruling over one universe i want to rule over the multiverse.
3.when merging galxies its not soppused to all spread outwords in an explosion type thing. It should realisticly merge to create a bigger galaxy. Sometimes even turning a spiral into an eleptical.
4.more star type variotions like meadiem mass,(our sun) high mass,and small mass (like red dwafs and such.)
5. star and planet life cycles. like protostars,supernovas,red giants,protoplanets,nebulas etc.

Thats all i really want added at the moment.

1) A tool to measure distance in a straight line.
It would be nice to have an option to select two bodies have it measure distance (either from center or surface)

2) A solar system model that would represent the actual positions of our solar system for let us say 500 years. Not necessarily a simulation. Scripted would be nice as well, for a start.
Not just our system, but any star system :)  I would even settle for not watching the fast-forwarded progression.  Just say how far you want to jump in time, let the system do the calculation... even if it takes 2 minutes to run (I'll go make some coffee in the interim)

I'm pretty sure the 'distance from you' and 'distance from from x' is from surface to surface, otherwise it might be confusing.

Anyways, I agree with this. There have been many times that I wanted to see how close two objects were which aren't 'gravitationally connected'. It's possible to do it crudely by zooming in close to one of the bodies, right clicking another body and extrapolating from the distance from you.

Better Explosions
Better planet collisions

Better collisions is 100% in. Not sure about better explosions, however it was implied that the way explosions work might change. Having more control over the explosions would be good.

What I would like to see:

Much more advanced atmospheric models (not sure how advanced Dan is going to make it though)
Inclined object placement planes (it's locked at 0 atm)
Roche limit functionality

Not sure what else though as US3 will be awesome for sure.

I would like to see an effect of time, for example the birth of a star and its end as a red giant or supernova, resulting from the start-up-parameters, so a life-cycle-simulation of a starsystem would be possible.

I also would enjoy a improved version of the object-placement. More precisely, the additional option to add a object according to parameters, i.g. "1 mio km X, 2 mio km Y and 0,5 mio km Z away from object ABC". Another recommendation in this direction would be the possibility to save groups of objects, i.g. hole solar-systems, to place them as a hole in another simulation.

Got this sim over weekend and have yet to put it down. Thankyou Dan! ;)
 
I would like to see objects gain mass from being in a dust clouds. (Theres nothing like growing your own planet from scratch.)
Also; I would like to see gas clouds ( or nebulas as some have stated.)
Even a mixture of both? Make a dust and gas ring,  add a small mass, let time roll on...
Degrading orbits? I know the moons of Mars and Saturn are slowly being pulled in. would be nice to simulate.

Only thing though is that right now, dust is actually made of massless particles, not bodies. However, Dan is looking at ways to simulate planet accretion.

Degrading orbits in the way you mean requires tidal forces, which I don't think we'll see anytime soon (not this year anyway), however there are ways to manually force the orbit to degrade.

To smjjames,

Thanks for the welcome!

lol, yeah I know my desires are a bit out of reach, I deal more with the flow of electrons than with coding of simulations.
I have some theories however, I'm going to perform some more rigorous thought experiments on the subject.
Title: Re: What do you want Universe Sandbox 3 to have?
Post by: Steroidkloud on February 15, 2012, 11:23:32 PM
What I am hoping for is a list of over 100 known stars to chose from (Possibly over 1000). Not the main 15 or 20. A list of over 100 known planets including Extra-solar Planets (Possibly over 1000). Not the main 15 - 20. The same goes with Asteroids, Galaxy's, Nebula's and whatever else is added.

I want the ability to create a Star, Planet, Galaxy by putting a custom texture on it and defining it's stats and then actually saving it as a default selection to choose from so you don't have to create it again in a new simulation.

Something like GFARGO ?

- http://fargo.in2p3.fr/spip.php?article100 (http://fargo.in2p3.fr/spip.php?article100)

Would be very nice ( very, very nice !), but I think it would be difficult to implement in the US

Or not ?

You can't do that without breaking physics.

Can you speed up the velocity of a moon and have it in the same SMA?

No? I thought so.
Title: Re: What do you want Universe Sandbox 3 to have?
Post by: vh on February 17, 2012, 03:00:18 PM
Making the SMA larger causes the planet to slow down i think.

Although a locking feature would be cool, an "unstretchable" cable to hold a body in orbit at any speed.

That option would be nice, however as Ubox is right now it is quite accurate on calculating period and sma.

I have been reading these days about famous comets and gradually been recreating a system than includes Halley, Hale Bopp, Swift-Tuttle and Hyakutake. I was impressed with what Ubox can do specially when adding Hyakutake and that is because he is a really long period comet. His original period was 13-14 k years.
http://amazing-space.stsci.edu/resources/explorations/comets/lesson/facts/Fact6/index_nf.html (http://amazing-space.stsci.edu/resources/explorations/comets/lesson/facts/Fact6/index_nf.html)
However when he passed from our system, he was greatly affected and his sma became 1700 AU and his period about 70k years! Obviously Ubox can not simulate his exact velocity at each point of his journey, however putting him at a 1700 AU sma and completing his other parameters that are easily found with a google search, you get about 70k years period.

Post by: Shturmovak on February 19, 2012, 11:48:41 AM
I am sort of new to Universe Sandbox so maybe my suggestions are simply based on ineptitude. However, here's some thoughts.

1. The moving around of objects is a bit counter-intuitive, especially in relation to relative height compared to a system's "horizon."

2. Textures are a bit weird in the way they are assigned to planets. When I tried separating my textures into neatly organized folders (as opposed having them in one big place) and then typing the name into the texture field (with <name of folder>/Filename.whatever), the game would load a texture, but forget it on a next reopening. I'd suggest an explorer type of dialog to open, so even if textures are forgotten damage could be repaired with just a few clicks. I'm sure such a feature can make customize options even greater.

3. Orbit parent is getting fixed right :P

4. From what I've noticed about the game, it's not very optimized. Truth to be told, there's a hell lot of gravity math probably bogging down the CPU, but graphic-wise the game is not spectacular (I'm not talking about the introduction of unrealistic stuff). Planets are not very spherical, dust=slow motion, planets do not cast shadows, etc., etc. Or maybe, again, it is simply me who doesn't know how to tweak it. I know the game is going to get a visual buff with the new version, but I was curious to know whether it would be simply a buff, or perhaps a rework because my average, soon to be below average machine would like really much to play the game as it's meant to be.
EDIT: NI think I answered myself that, so sorry for it :) "This is a full rewrite of Universe Sandbox in a new 3D engine." says Dan here: http://universesandbox.com/forum/index.php/topic,5865.0.html (http://universesandbox.com/forum/index.php/topic,5865.0.html)

Anyway, I apologize, if some of the things have already been said. I'm a bit of a noob and haven't really lurked around the forums for too long (a thing that's probably going to change! :P), but from what I've seen from the game/experience Ubox and it's community are one of the most relaxing things after a hard day :)

Kevin, have you seen the screenshots and read what Dan has said, some of those stuff WILL be in US3.

@mudkipz: For roche limit, I would guess have it function, no idea about hill spheres as they work fine to me.

7: Wouldn't it be better to just change the skin?

10: Given the new atmosphere effect, we could very well see this.

14: The same would also apply for primordial planets.

16&17: Come on, its a gravity simulator not a geology simulator.

currently dust and gas are shown by particles. Nebulae are possible as objects, but you'd have to make a 3d model and it'd be a solid, not a liquid or gas. It might be possible to add them, but the simulater would need a fluid dynamics thingy

cloud system for the terrain planets and gas giants:

1:put a cloud system for planets if it's possible the clouds will give a realistic feel to the planets.

2:if this is possible can you put a lighting effect for planets?

3:for gas giants can you put a dynamic cloud band systems  it would be cool to see the clouds whip around the planet.

4:went asteroids hit the clouds make them move away form the impact zone.

water effects: if possible for US3:

1: put water reflections for terrain worlds

2:put water vapor went the planet gets to close to it's host star.

3:put water to freeze or lock up in ice went the planet gets to far from it's host star.

4: put water light reflection went the Cameron faces the star.

planetary collision,asteroids impact:

Hahahaha this one will be hard.

1:put planetary ties went they get to close to each other.

2:put some like N-body sim into the collisions

3:went a asteroids get to close to planet let them start to drag across the atmosphere and break a part on impact

4: let asteroids leave impact craters on the planet

5:went the asteroid impacts the planet let some of the asteroid fly off into space and land back into other parts of the planet and rain back down all across the planet.

Hmm, they already do the #4. Do you mean physically for thr 3d model? That'd be pretty hard :P and i can't imagine more than a simple circle.

#5. Intersting idea. Maybe an option to set a speed. Under this speed, objects bounce. Above this speed, objects collide.

Well, there is a completely new collision system, but none of us (other than Dan and the other devs) know any details about it yet.

For #3, Dan has said that he wants to implement atmospheric drag.

For number 1, are you talking about the relation lines when you push ; ? The relation lines sound like the same thing as what you mean, otherwise that one needs clarification.

Stars:

Brown Dawfs: should have a very active srface. like very second the star sould give off a massive solar flear and it's so red and dim itmay look a jupiter in some way.

Rew Dawfs or M class star: these guys are like the brown dawfs and more active in thier solar flaers they sould look like a star that is going into hyperdrive in solar actives.

Organ Dawfs K class stars : they are more clam and have less solar actives they sould look like our sun but smaller but they have a organ tined to thier color.

yellow Dawfs G class stars : Our sun is in this same class of stars and sould have a very slow solar actives a few massive solar flaers might go off here and there.

white-yellow giants F class stars : these stars are capable of going super nova and have some times massive super flaers. this can sript  a planet bear of it's atmosphere. they sould look like our sun but bigger

white or white-blue giants A-B class stars planets can't form here beacuse of it's short life spand they have they most volite solar flears and can go super nova these stars can form blackholes they sould look like our sun but looks like on stroids.

blue-purple super giant O class stars: these are the biggest of the big hyper super massives solar fears can happen on these stars and can go hyper nova they can form massive blackholes they have a very blue or purple look to thire colors.

Black holes: in the US3 black holes are going  to be awesome in the next Major update.

1:should have  a pulling effects on stars and most likely pull the star a part.

2:black holes should have a a massive disc went the star is being engulf by the black hole

3: should have rays shooting out form it's polar regions went it's eating a star.

I will think of more ideas for the black holes later on. but I will need to move on.

1:Speed-accuracy needs a major update it needs to be improve to keep the planets orbits more stable to prevent the planets form flying off into deep space.

what do you mean? i'm pretty sure it's physically impossible to simulate faster and having it all stable

Although what if 'orbit' were calculated and then the body was locked inside that path until something happened. Like vector graphics, *analogyised*

currently dust and gas are shown by particles. Nebulae are possible as objects, but you'd have to make a 3d model and it'd be a solid, not a liquid or gas. It might be possible to add them, but the simulater would need a fluid dynamics thingy
nebulae could be built as galaxies... when you zoom into a galaxy it's nothing much but zoom out and it's big and beautiful :P

1) Have an "ejection-proof" check to prevent bodies from being launched by large timesteps.

If they can't be processed properly at those speeds, it would just "disable" the effect of gravity on the object and keep using the last recorded full orbit. (Moons and planets that are close enough to a large body to be ejected by a large timestep typically don't have a big gravitational effect anyway, and they surely don't influence other objects in the system if they are catapulted out at the speed of light!)

2) Calculated absolute and apparent magnitudes

It'd make it easier to judge the brightness of an object if those two were listed under the detail list that appears when right-clicking on something.

3) Have auto-orbit select the barycenter in a multiple star (or planet) system.

4) Have an option to allow barycenters and landing points to be hidden from view

Currently, I just make them black, because when I'm viewing a system from a landing point, by default it leaves a white dot in the middle of the screen.

5) Temperature-based textures.

Possibly, Universe Sandbox could have an "advanced" tab underneath the default texture area to allow the user to place temperature ranges for other textures. Universe Sandbox would then just blend from one texture to the other once the planet starts to approach the edges of two texture ranges. This effect would be especially awesome if different sections of a planet had temperature calculations. (Dynamic ice caps, even on tidally locked planets!)

6) An optional reflection map for planets

It would be really cool to make rocky bodies with noticeably varied surfaces

7) Tidal bulges based on rotational speeds or gravitational effects

8 ) Temperature changes based upon large impacts (i.e. a molten Earth if it is struck by Mars, somewhat related to 5)

9) Light falloff for dust particles.

Currently, dust is just as bright at long distances from light sources as it is when right next to them, making it hard to view dust-filled systems from large distances. Similarly, stars don't have a significant light falloff with distance, either.

10) An optional aurora effect for atmospheres

11) A label option that only indicates major bodies (i.e. stars and planets, but not moons)

12) This is stretching it, but an option to convert all bodies not contained within the nearest solar system into a background texture.

Basically, if you selected "Convert to background" while viewing our solar system, any other solar entities are placed onto a texture sheet that can be used as a stellar background in Universe Sandbox. That way, someone could create their own constellations and galaxy placements without being overly taxing on the system.

13) The ability to place reference points on a background image, effectively allowing stars to be labelled without needing them to be processed in the physics engine. Of course, that means that you couldn't zoom in on them and view space from their point-of-view, but it could help out low-end systems. (ties into 12)

14) An infrared viewing mode.

15) Orbital and rotational options to make it easier to achieve resonances. (Other than 1:1 tidal locking, of course)

16) Satellite and spacecraft models.

It's been mentioned countless times, but it would be very cool to view space from an object with a controllable velocity!

For #1, I'm not sure how that would be achieved.

#3 is definetly being worked on, or rather the auto orbit or orbit parent function needs to be reworked and it does need to work properly for binaries, etc.

I'd like to add to #9 in that there needs to be more of a fade out with distance from the star (or stars) rather than a sudden cut off at 100 AU with default brightness settings.

Oh yea, how about when there are two or more suns (well, two or three would be reasonable), the planets don't look like someone took a magnifying glass and focused it on the object.

#1, smjjames, i think Dan referred to it as a 'jettison issue' here (last posts) http://universesandbox.com/forum/index.php/topic,6009.0.html (http://universesandbox.com/forum/index.php/topic,6009.0.html)

so it is fixable maybe with this 'smoothing' although i'm not sure if it applies to objects as well as particles...

"Oh yea, how about when there are two or more suns (well, two or three would be reasonable), the planets don't look like someone took a magnifying glass and focused it on the object."
Hmm but isn't that how they'd really look in real life?

I don't really know to be honest. I know there would be increased brightness, thats clear.

11) A label option that only indicates major bodies (i.e. stars and planets, but not moons)

As of right now, planets and moons aren't seperated by class. If you place a random 1,000km radius object, it's impossible to tell whether it is a moon or planet. Past a certain mass, an object becomes a star and has luminosity, but i don't see how you could differentiate a planet from a moon

Wow... another great list of ideas.

Thanks for this.



The 'jettison issue' is a combination of high time steps and lack of smoothing.

Gravitational smoothing is well explained by an paper written by Thomas Greenleaf:

"There are two problems related to the force of gravity. Firstly it has infinite range and secondly it goes towards infinity for point masses when their distance goes towards zero.

The infinite gravity at zero distance is dealt with through gravitational smoothing in which the point gravity source is replaced with a source with a non zero radius. Obtaining the gravitational potential is then changed from a point sample to what is in essence an integral of the sources mass distribution over a volume.

The problem with the infinite range of gravity is dealt with exactly the opposite way around through hardening. Here a distributed collection of gravity sources will be approximated by a point source rather than as the sum of individual potentials."

US could classify a planet as any non-light-emitting body that has a mass higher than 0.01 Earths and is orbiting a solar body. (Or the reverse, any object that is smaller than 0.01 Earths or orbiting around a non-light producing body is not a planet)

Wow... another great list of ideas.

Thanks for this.

You're definitely welcome!

If a star exceeds the Eddington limit it'll blow off gasses that might let you hear sound.

smjjames, if i understood the article correctly, it was talking about supernova's making sound because the gasses from the star were launched out in space, creeating a medium for the sounds to travel though.

Okay, okay!
In general, stars do not make sound.

well spaghettification would be interesting
Solar Storms
weather system for planets
Magnetars and pulsars 

also when a object with a high amount of gravity enters a star system I'd like to see the effects in more detail
like distorting of the star(or stars if it's a binary system) , atmospheres and oceans like
if a giant star powerful enough got close to our star system it could in theory cause all our oceans and clouds to flood what ever side of the earth is facing that star 

and as that giant star got closer to us i'd like to see that star to incinerate the surface of our planet and it's immense gravity to eventually cause our planet to crumble and break apart
also if the star is large enough it should cause our sun to distort in shape

also if it's a black hole entering our solar system I'd love to watch the oceans get suck up and eventually cities and forests to be pulled from earths surface as it crumbles and gets suck in to the black hole


and I'd love to see like say our sun was suddenly 1000 times Hotter i'd like to see that effect the planets more
so like the side of the earth facing the sun could be a molten hell then that side could cool down and be a barren waste land when not facing the sun


also it might be nice seeing satellite in orbit around planets


and I think someone already said stars should have life spans
the bigger the star the shorter the life spans
also what happens at the end should also differ on the size of the star you know
I'd so love to see a hyper nova :P or our sun turn in to a red giant then eventually a white dwarf



also I think we need more galaxy's and stuff
such as the deathstar galaxy

Well, we may or may not get all those features at once, but most of them seem pretty resonable. Spaghetification could be done with some viausal effects like gravitational lensing is. Solar storms/weather could all just be animations. Pulsars could shoot light pulses and magnetars would have toggalable visible/invisible magnetic fields. The part with the gravity making planets crumble apart can actually be simulated in this version, and in the next version it might be made easier. You can also easily place satellites in orbit, just pick an objecta and turn it's SMA down until it is in near earth orbit. also a setting to maek starts explode after certain time would be cool, but it should be toggaleble.

Universe Sandbox doesn't simulate relativity or bending of spacetime, so it'd be mostly visual.
Most of the suggestions are pretty mush visual enhancements. Roche limit can easily by simulated by being able to autoexplode objects.
