RE: alien skies - James D Jarvis - 05-06-2022
Cooled off some of the stars (more variance to the color). Added in reflective water, not thrilled with it yet but it's on the path.

Trees Reflection
Here is an example of water reflection and trees too for that matter. I hope it helps add to this wonderful project. I have to give it a thumbs up because you got me pulling out old old code and translating it to QB64!
For water reflection pick horizon line across screen, measure from it to top and from it to bottom and scale (fit) the sky into the bottom water section in height (width is 1 to 1). Map!( ) function might be useful.
Oh heck might try a _PutImage of the sky flipped upside down and crammed into the water section, all I've done is a lakeside view across the whole width but puddles could be made by drawing ground to cover reflected points where you don't want to see them.
The trees have branch widths indirectly proportional to level from trunk.

I have animated the above still shot and used _PutImage for reflecting the animation every 1/30th of a sec. see bplus Proggies thread.
RE: alien skies - James D Jarvis - 05-11-2022
Fiddled with water more. Trying to get the fluid to look like it's not always water but still provide a reflection of the sky. Still far from perfect. I'm getting a true reflection now (positionally) but due to how the routines are setup I'm not getting mountains to work just yet. ( have to move things about a tad probably pull the ocean code out of where it is in rendering order).
