⭐⭐ 3D Spaceflight Simulator️/Kerbal Space Program
3D Spaceflight Simulator 0.0.78

TurboWarp Link
Thought I might catch your attention with emojis.
I am posting this because I know there are a lot of people on this site that like space
and/or spaceflight simulators, so I figured a decent number of you would want to see this.
Here is one of the first working 3D spaceflight simulators made on scratch.
You pilot a small ship through a scaled down solar system and get to explore how orbital mechanics work.
Similar to Kerbal Space Program, however the physics is very basic and only one vehicle without parts is available.
This is about the closest you will get to kerbal on scratch.
Current features include:______
- Realistic orbital mechanics/Orbital line drawing
- Time Warp feature
- Astronaut
- Black Hole with accretion disk similar to interstellar movie
- Realistic Gravitational lensing (Calculated with general relativity)
- Scaled down solar system for ease of travel
- Realistic Rigid Body rotation (intermediate axis thm/tennis racket thm/Dzhanibekov effect)
- Reaction control thrusters showcase
- Atmospheres with unrealistic light scattering
- Solar glare
- Ships in planetary shadow appear darker
- Cannon from the ship: still in beta; use at your own risk
Things I am aware about but have yet to add:______
- Shadows on planets/terminator line (Hard to draw them as triangles without them interfering with my current engine)
- Part system for buildable craft (will add hopefully in v2)
- Astronaut cannot walk on planets and can only use “Jetpack” (unacceptable i know, but will be fixed in next update)
- Game mode with realistically scaled planets (technically exists, but is hidden in the code because it is not finished.
See questions sprite to change the current solar system from 1 to 4)
- Asteroids
- Planets are barren and empty (I plan on adding features for this currently the
only object is a lone tree next to spawn)
Things I am aware about but decided not to add:______
- Realistic Black hole orbit physics (will remain Newtonian,
general relativity is hard, though the visuals should be realistic)
- Textures on the astronaut and ship (My 3D engine does not support this)
- Realistic collision with craft and planet (Collision math is very hard, so I have done simple physics.
If I can figure out the math for realistic collisions, I will add them in a future update)
If you have any suggestions on what to add let me know, I have been working on
this for a while and things are slow going, but I do have plans for
it in the near future.
I have started working on a second version that will be more realistic and focused on the
activities of an actual real-life Astronaut abord the International Space Station.
Progress is slow going however, due to the things mentioned earlier.

Finished working on the terminator. I'm now working on adding ground detail.

Bringing up my post again so more people have a chance to see it if they would like to.
Still working on ground detail, currently trying to figure out atmospheric drag and re-entry. I plan on making this a spaceflight simulator with realistically scaled planets, decent physics and real life spacecraft/aircraft. If any of you that see this have suggestions or ideas let me know.

Bringing up my post once again because I know more people might want to see this.
Working on adding save codes and a part system, which will allow for custom solar systems and vehicles.
Once I get this update working and more polished, I will publish it to the current project.
In the meantime, if you think of anything else that would be cool to include in the game let me know,
just be aware I will be slow to add things.

At this point I'm using this post as a dev-log. Recently I added eclipses and I'm still working on the parts system, but so far its coming along nicely, just slowly.
Snapshots of progress but not currently published yet:
Space Station entering night time over Real scale earth:

Shadows on planets and eclipses:

Parts system test: (each astronaut is a part rigidly attached to main craft)

Thats so cool!Thanks man. I'll do my best to keep working on it but things are still slow going at the moment. Ill try post any new updates here before I am able to release them back to the project.
