Realtime 3D sky generation (Online Applet)

[DzzD]

here is a WIP I am working on (with a trainee) to generate sky appearance in real time that we will soon use in our game.

note that it is still a WIP : some problems still appears in rendering and it is not yet fully optimized.

for each frame the Applet generate the five skybox texture, apply them to a skybox & render the frame

What you cannot see online :

The current version enable to set a location on earth and a date to generate the sky with the correct sun location ( it should also soon put the correct clouds coverage of the selected area)

It can also generate the sky reflection map texture ( the one you may apply on reflective object : chrome/sea/etc…)

I kept adding more clouds and got:

[DzzD]

this is a bug, something that it is not handled ( heu… do I mention that I was working with a trainee ? you may also notice that the applet is continuously requesting focus )

[Addictman]

A few glitches in the sky, but still, awesome!

@Addictman

A few glitches in the sky, but still, awesome!

theire are still two visibles bugs :

• mapping on the skybox is not perfect (you can see skybox edge sometimes)
• some artefact (strange points) appears on clouds when generating them (I suppose this is because rendering appear while clouds are generated)

[Mike]

Really nicely done (except for the glitch and out of bounds :))

[DzzD]

we’ve gone further with this project :

• moon added with real appearance ( phase & path ) based on location & time
• sea also added

everything is dynamic : cloud cover, sun, moon, sea wave ( and can be rendered in realtime with 3DzzD in software mode )
