About

Pshine ("planet shine", name inspired by KSP mod of same name) is a work-in-progress open-source space simulator "game" written in Vulkan and C23 (because why not). Currently, the implemented features include:

Atmospheric scattering
Patched conics orbital simulation
200 lines of octahedral sphere (not terrain!) mesh generation
Simple sphere LOD system
Real sizes/values (so the Earth's radius is 6,371,000 meters)
C23 math library with a goofy python generator
Silly build system using only ninja files

I plan to add:

Proper terrain mesh
Minimal spacecraft simulation (so orbital maneuvers)
Other stuff probably, I don't know

NB: I'm only working on this when I feel like it, this isn't anything serious.

Screenshots

Showcasing the User Interface and differnet celestial bodies' orbits. View from Earth, the Moon is visible, the orbits of Jupiter and Mars are visible (and their labels).

A sunset on Mars, from high above the ground. The dark Martian surface is taking up the right half of the picture, with a gradient from pale blue near the surface to orange, with a small dot of our Sun in the middle.

View of Earth partially in shadow from ~10 million km, with the Sun visible on the left.

Sunrise from space (or almost space), Earth fills up the right side of the screenshot, with the atmosphere showing a gradient from green to blue.

Earth and sun from very far away, so that half the Earth's orbit is visible.
