Orbiter Screenshot Thread

That's definitely so!

And we should investigate the effect of a large number of trees, building and other objects on Orbiter performance.

I think we can try placing trees, houses on the ground, and this will make the flickering of surface textures less noticeable.

Also they make place like airports look much more real, give a feeling of speed when rolling on taxiways and runways...

That tree above looks perfect. How many polygons ?

They are just two very thin cubes placed in a cross. So like 24 tris total (or 12 polys). And, it could be reduced by half if they were replaced by four planes instead.

We need to learn how to meshes visible behind transparent meshes! Then we would have trees!

Meshes with a transparent texture must be rendered last, otherwise the meshes rendered afterward will also be transparent.

That should work fine in Open Orbiter after adding a mesh group flag 0x20 to the tree. It should enable Order Independent Transparency. This works only in a one bit basis. (i.e. either fully transparent or opaque).

Finally decided it was time to make Pioneer One into a VesselBuilder vessel so I could finally use my interplanetary spaceship. Here it is docked to the CSS in a test scenario to test the crew docking port.


Now I just have to do the four pods.

To protect its crew from Solar radiation, the mining vessel Konstantin is hiding in the shadow behind an asteroid. Solar panels extend on a mast over the horizon to capture the sunlight. The ship is spinning at 3 rpm to provide Earth-like gravity in the habitats at the end of the booms. Solar miners - currently stored in the lower part of the ship - will be deployed to melt and vaporize the regolith by focusing sunlight through their reflective mirrors.

The scene is inspired by the novel 'Delta-V' by Daniel Suarez. If you are interested in a near-future space thriller, this book is worth reading.

wow
we definitely need new thread "the story behind screenshot"
well done francis

 

[francisdrake]

We definitely need new thread "the story behind screenshot

Thanks for the praise! I will open a thread on the Delta-V novel and its spaceships.

Is that actually Ryugu, or did you use a different asteroid?

I scaled-up the Martian moon Deimos and put it into deep space. Against the Suns' backlight, it is hard to see the default surface texture.

I looked up Orbit Hangar, but it seems nobody yet modelled Ryugu. There are high-res surface photos on the Jaxa website. I would be glad if someone takes the challenge to make a proper Ryugu.

I have a config file for it with correct orbital elements, but a generic mesh.

NASA's solar system treks has a 3d model in a few different resolutions:


It is in obj format, but it's not textured:


Same link also has the Hayabusa2 global DEM (Digital Elevation Model). One can make "proper" surface elevation tiles for Ryugu with that.

Thanks for the links! Above is a first shot, using the asteroids 3D mesh,
and the surface texture from the JAXA website.

Speaking of NEOs, is there a comprehensive list of all the known ones somewhere? Somehow you'd think that "list of near earth objects" would yield an instant result on google, but all I can find are lists of approaches rather than just an overview of the objects and their orbits.

Here you are helped:

IAU Minor Planet Center

We are the official body that deals with astrometric observations and orbits of minor planets (asteroids) and comets.

Neat, thanks!
