Win32 limited Celestia to only Windows desktop, so there was the idea to bring Celestia to UWP, hopefully Celestia gets to run on where any UWP app runs. For example, on an Xbox.
So here is how it looks, and you can grab it on Microsoft Store if you are running Windows 10 1803 or later.
UWP is a walled garden, so there are lots of limitations...
1. No OpenGL. UWP apps cannot use OpenGL, so has to use ANGLE to render OpenGL ES. As a result current Lua scripts involving drawing will not work.
2. No access to read from/write to arbitrary folders. For customization, read Wiki.
3. Very bad multi-window support. There is support for multi-window, however so bad that I did not use it in this build at all.
And yeah it is open source on github. Core of Celestia is wrapped in a C++/WinRT (can be used in C++/C#/JavaScript) library and UI written in C#.
I'm hoping that we could move to WinUI when ANGLE supports WinUI, the migration path should be fairly simple from UWP.
