Great work!

I'd suggest to move your celutil/gl.h to celengine as this is a more correct place for it. It will be later moved to celrender/ subfolder when I remove rest of GL calls from from other parts of engine. I also possibly will remove GLU completely, we use it for mipmapping (natively supported in GL>=1.4) and error reporting (basically useless, maybe i removed it already).

And no need for "#ifdef __cplusplus" as we use C++ only.

Very Cool, but at that point that build is well below an alpha release and there will have to be a way of getting addons onto an iOS version of Celestia.

that commit definitely still needs some more modification, looking forward to making it happen. making it available on iOS means it will work on Android too, as long as there is an Android developer around

still a lot are missing, for rendering, texture and font are very broken, also user interaction and detail UI are not implemented. there will not be a release until I get the essential part working.

Is it just me, or is this the birth of Celestia for Smartphone?

It is, and soon there may be something on Android. Which will mean more versions to archive, which for Android will be easy.

got the texture working, used a previous version of gl4es so it should be gl4es's problem that it wasn't working. so now the earth has a surface now, with atmosphere turned off.

It somewhat reminds me of version 1.0 under Windows now.

some new results, with the correct depth format set, atmosphere, rings renders correctly. added some interaction, if anyone is interested, he can check in the video in the attachment

Those look good indeed

Agreed, you just want to try and set the field of view to be higher.

And, there should also be a feature to allow you to make your own celestial bodies, so that we can do our addon-making in there as well. Though if you want it complicated, then perhaps, it is wise to buy a really powerful SD card for that. I'm looking at you, anyone who is going to make very large and comprehensive addons in there

I'm in the "anyone who is going to make very large and comprehensive addons in there" category

Indeed you are. Hope your phone doesn't crack or break internally

I will upload a beta version on TestFlight soon, so anyone can try out on his phone.

the beta testing link is online, check the original post, you can share it with other people, so there can be more people getting involved in making it better!

So when will the Android version come out?

Markers, is there a way you can add this to the Archive repository?

This is going to be a major development in the future, so I'm putting it in Announcements

i can't really speak for this, i have very limited development with Android. but if any Android developer is willing to volunteer, i could provide help to get the renderer to work on Android

the binary would hardly be useful, one can only install iOS apps from AppStore/Testflight on normal iOS devices.
