sfsim is a space flight simulator with realistic physics and a true-to-scale Earth using NASA Bluemarble data.
Current key features
- Realistic Physics: Simulate space flight and aerodynamics.
- True-to-scale Earth: Earth model based on NASA Bluemarble data.
- Realistic atmosphere: Atmosphere with realistic temperature and density as well as procedurally generated volumetric clouds.
- Real celestial body positions: Position of Earth and Sun based on NASA data.
\n\nHi,\n\nI finally managed to release version 0.5-1 of sfsim.\nsfsim is a realistic 3D space flight simulator with an advanced single-stage-to-orbit space craft.\n\nThe new version comes with rocket plume graphics.\nThe plume was implemented using OpenGL shaders and uses volumetric rendering.\nI used the Shadertoy website to get ideas from other users and to develop the shader.\n\nThe rocket plume shows Mach diamonds when the atmospheric pressure is high enough.\nIt then expands with decreasing atmospheric pressure.\nIf you want to, you can try out the Mach diamonds shader in your browser.\n\nThe difficult part was figuring out the plume behaviour for different atmospheric pressure values and also the integration with the volumetric cloud shader.\nThere is still some work left to be done for sfsim, but most difficult problems are solved now I think.\n\nLet me know any feedback and comments in the sfsim playtest discussion forum .\n\nEnjoy!
