Realistic shapes/maps of known Solar asteroids/comets

15 Jun 2017 20:08

Hello! I did talk with SpaceEngineer about this some time ago and I wonder if anything can be done to add the realistic maps and shapes for Solar System's asteroids and comets for this information is available. I can not do this myself because I do not have much tools for that and I do not know how it is done for SE. So I am asking if someone who knows how to help with this could do this. The site includes information on pole positions on the model.

Here is site that includes shape models and map for well known objects: https://space.frieger.com/asteroids/

Obviously the most detailed model should be chosen when the site has many for one object. These are models based on radar or spacecraft data. Most light curve based models are not very precise. However some of them were less sharp angled and maybe could be used in SE. Some of these objects were added to the catalog with my catalog update.

Comets:

Halley's comet (1P): https://space.frieger.com/asteroids/comets/1P-Halley
Tempel 1 (9P): https://space.frieger.com/asteroids/comets/9P-Tempel-1
Churyumov-Gerasimenko (67P): https://space.frieger.com/asteroids/com ... erasimenko
Wild 2 (81P): https://space.frieger.com/asteroids/comets/81P-Wild-2

I would love to see these models in SE, but I don't have the modding skills to do it

It is a shame I do not know how to do this myself. Do you know anyone here who could help with this?

Permian Therapsid, well, creating this thread is a pretty good start

i could probably do them. it would just take some time. as i have done with Proteus and several other objects http://fav.me/da9foan i might get to it one day doing the other asteroids = )

Thank you, that would be very nice thing to do. Take your time of course. I understand this kind of work is not done in no time.

With recently implemented static space ships, it's possible to expand this system to render any kind of planetary object with a custom model (as like Celestia did). So you may start importing obj models of asteroids as "space ships" (using the manual). When complete, email models to me, and I start upgrading the static ships system to use those models for asteroids.

if needed for each model I can create a procedural diff and norm texture.
something like this:
diff.jpg

norm.jpg

This would be an ideal system. certainly for objects like 67P, where doing a cylindrical elevation map would be ridiculous and impossible due to overhanging areas.
