OHM Nebular Vortex

 Nebular Vortex  
 
This addon is a further attempt to create something that resembles a nebula (all be it a very small one). You can change the appearance of the nebula in several ways;
 
A) Change the color (i.e., emitter ships) in the scenario. In the documents folder I have included a representation of the relative positions of the attachment points.
 
B) Increase or decrease the number of emitter ships.
 
C) Change the characteristics of the particle emissions for individual ships (found in the config/vessels/vortex folder in Orbiter.
 
D) Change the speed of rotation of the Vortex. By pressing F4, select ship, GR-0, in the menu in Orbiter, and pressing 6 on the number pad to increase the rotation.
 
 Artlav's gravity tool is at the heart of this addon, and I want to extend to him my gratitude for allowing me to incorporate his work in to my concept.
 
 I would also like to thank BrianJ for his nebgen module which made this all possible, and to T.neo for his nothing mesh.
 
 Issues;
 
  A) When I started this project, I wanted to incorporate Artlav's gravity tool to create an increased gravitational effect that would slingshot a ship through the Nebula's center. However, due to the rotation of the nebula, the ship gets accelerated off to the right at a much slower rate. I don't know if this "characteristic" can be corrected.
 
  B) Also, there is an artifact associated with the emitter ships which can be seen after you exit the nebula and get a certain distance away.
 
 I have included Artlav's read me for his gravity tool, so you can change the parameters. The gravity tool is located at the center of the nebula, so pilot your ship to the center of the vortex.
 
I have also included the set up mesh (in the documents file). If you want to see the relative position of Artlav's gravity tool, substitute the set up mesh for the original mesh (don't forget to replace it with the original mesh afterwards.
 
 The size of the nebula is about the same size as the entire KSC area. To make it any larger would entail adding more emitter ships and this tends to increase lag time.
 
In the scenario folder, I have included a scenario labeled "Emitter ship TEST". To better visualize the color and particle characteristics of each individual emitter ship, simply replace the emitter ship name in the TEST scenario with the name of the ship you want to look at.
 
 As always, input and constructive criticism is welcomed and appreciated.

Hi stevecast.

I haven't downloaded any of your nebulae, but they look very nice in screenshots.

Would it be possible to use the particle emitter ship concept to create earth auroras? The colors of the nebula in your screenshot would be perfect, I think.

Hi stevecast.

boogabooga :lol: (I like your handle),
I think that it would be possible, but since the emitters are ships, you would have to have them in a geosynchronous orbit which would not decay (possible?). If you look at the emitter ship config files, there is a lot that can be done in terms of emission parameters, but also direction, speed, and light source of emitted particles.
If you would like to give it a try feel free...I was all ready to put the whole emitter/particle/nebula thing to rest,... but another seed of curiosity has just been planted...here we go again!!! :lol:

Would there be a way to limit the emission such that it is only active at high latitude? (ie write a code that checks latitude) I'm thinking emitters in polar orbit that only emit when >~60 degrees or so.

Or...ships that hover in place with super-high ISP hover engines. Or really long ships that sit parked on earth and have the emissions eminating some 100km above them?
:hmm:

I was just thinking the same thing!! In the Hellsgate Base addon, the emitter ship that is used in the volcano is basically an emitter ship attached to a very tall ship (config/vessels/HGELE) (concept by Jon Marcure) that is placed in the center of the lava cone. With the correct height and by manipulating the particle emissions, an approximation to an aurora may be possible.

I think you could probably just code the vessel to stay at x height, y latitude, z longitude, ... you get the idea. I would have to check the API to be sure though.

If you would like to give it a try, I'll supply you with whatever files you need. Just let me know. It would be cool to see an aurora in Orbiter.
