Maybe. A simple texture moving on a star surface... I don't see it being too difficult to make it simple.

Unfortunately, I think animated or moving textures aren't possible in SE at the moment, but they are planned. SO I guess we'll see procedural solar flares in a later version.




I occasionally stream at http://www.twitch.tv/magistermystax. Sometimes SE, sometimes other games.

No need. A curved fire texture moving in an arc-like pattern can be a simple substitute for a solar prominence. Maybe a fading out fire texture can be used for a flare.

Probably better to code a shader or particle system for that, to have each one be generated uniquely rather than having an identical texture "fading in" once in a while. Perhaps elements of that could be used to generate new galaxy and nebula gas formations later on.

Now that Space Engine has aurora effects, this kind of effect could be utilized elsewhere, right?

I'm thinking about the chromosphere of a star. I'm not talking about prominences; I'm talking about spicules and fibrils, which are far more numerous and probably a good first step to simulating the violent atmosphere of a star. They could be roughly based around the granular patterns currently seen in SE, or they could be based on their own random pattern. The aurora effect could be altered for this.

This would make stars more dynamic- it would help to make them "alive". I know I've said how aurorae help make space engine feel more alive about a billion times by now, but it's true. An active chromosphere would be amazing.

This will also mean that flying close to a star will be more exciting (and realistic), instead of just a corona and a granular horizon.

.98, hopefully?

I definitely second werdnaforever's idea here, I certainly like it. And I appreciate the detail.
In fact, I already enjoy Space Engine's star surfaces. But an active solar surface? That would be awesome.

I wonder how much further different kinds of effects can be used in SE. I guess it's a question of what openGL can handle. Dust and ice near planetary rings, exhaust from star ship engines, the hyperdrives on ships, rain or snow under clouds (whose color should be based on the color of a planet's ocean, and not just plain white, by the way...); these are all places where effects would be beneficial.

Also, I just can't wait for version .97.

OpenGL can of course handle all of the things you mentioned. All that is required is for the engine to be coded to accommodate them and for them to be implemented in the program.

werdnaforever, as I said, all space related stuff will be implemented in SE one day. Also, this should be moved to the Feedback and Suggestion forum.

Agree, but he just wanted to tell you that you could use the same way you made aurora to make chromosphere's effects, maybe this is the reason that he posted it here

(werdnaforever)

As the aurora do that for planets smile

werdnaforever, (and everyone) SE said it here but these lines have been added recently in the OP of the Todo list :
(SpaceEngineer)
Anyway, I should note: as long as SE is a scientifically accurate Universe simulator, then one day it will implement ALL space objects and phenomenon that are known to modern astronomy. So you may not bother yourself with questions like "will SE one day have meteor rain implemented". I guarantee that it WILL.

That should answer a lot of question cool

I understand space engineer wants to include all space phenomena- I was talking how certain things could be done. I wasn't really questioning whether they would be included at all.

I don't think think its a good idea to discourage discussion about how things could be done just because they will be- don't take that the wrong way though.

Ok, I've used the quote of SE just in case you or some people haven't seen yet, sorry if I sounded repetitive.

I can't disagree with that. smile

The sprite is a very powerful technique, it can be used and used in all games to create various effects like smoke, explosions, rain, etc. It is used in SE to render a star, galaxy and nebula, and particles of planets far away etc. Now it is also used for comet tiles and aurorae. Of course it can be used for solar flares and prominences, for 3D clouds on planets, and for weather effects etc.
