It means that Celestia development can make gigantic steps in the next few years.
Please list all planned scientific, visual or other upgrades here which were never implemented because of complexity or lack of coding participants.
My quick list (sorry if I listed features already in Celestia
):* Real n-body gravity simulation
* Gravitational deflection of spacecraft and asteroids
* Removal of shadow-casting size limits for small bodies
* Shadows for irregularly shaped bodies
* Multispectral / wavelength-based rendering
* False-color astrophysical visualization modes
* Camera optics effects (lens flare, glare, bloom)
* Higher-resolution planetary terrain and texture streaming
* Volumetric atmospheres and realistic cloud scattering
* Procedural galaxies and nebulae
* Interactive spacecraft flight simulation (not just camera navigation)
* Removal of hard-coded time range limits (e.g., ±9999 years)
* Improved and updated spacecraft and station models
* Full galaxy-scale rendering engine (celestia.Sci successor)
* Gravitational lensing visualization
* Relativistic travel / time dilation modes
* VR support (official upstream, not forks)
