Ecliptic? Eclipses?
You'll need a big black blanket with holes rotating with the sun centred on the Pole; better a fixed sun distance though.
The trick would be achieving 6-month days at the Poles.
I think I'll stick with the blobby Earth.
Amusing nonetheless,

This one will have you rolling:Quote:

More detail.
Background image is supposed to be a photo by Hubble. Strange how they can't do similar close-ups of the much nearer earth or the moon.
And your point is? How does this touch on X3D?Quote:

I believe that the images that salaam is posting were ALL created in X3DQuote:

Apparently the sun is 93 million miles away from us even though the sun rays through the clouds make it seem very near. It's just a coincidence that it looks the same size as the moon.
This is a photo animated in X3D:
Sorry, should have read 'hundreds'Quote:

Thanks Frances,
Here you go for now, the others later.
The Sun uses [Swing1] animation. It has 4 main parts (segments of the disc) which flap forward and backwards. Another part is the 'flares' which move more aggressively. Notice that the 4 segments each have a dot. This is so that all 4 shapes are the same size when pasted into X3D. The image texture of the sun is added in one go to all the 4 shapes together (with the cursor removed ie. no one shape is selected.)
The 2nd dish is a photo while the 1st was created in X3D.
Here in the UK, we don't have any satellites in space so all of our dishes are pointed to radio masts or towers. In fact I did look for photos of American satellites but they don't seem to have any either.

Sky is currently transmitted from the Astra satellites located at 28.2° east (2A/2C/2E/2F) and Eutelsat's Eutelsat 33C satellite at 28.5°E.

Thanks Egg,
Amazing piece of kit there:
The Sky satellite is able to withstand high and low temperature extremes.
It's able to open up it's solar panels in space.
It can manoeuvre in any direction using thrusters while travelling at 8 times the speed of sound in order to keep itself at the same angle and distance from the Earth's Equator.
It follows Earth precisely while Earth itself travels at more than Mach 1.
It can dodge other satellites and space debris.
It carries enough fuel for the thrusters for 12 years.
Receives and transmits data constantly.
It is controlled remotely from Brussels.
Although more complicated and harder working than any Sky equipment on Earth, it doesn't need maintenance in 12 years.
And to top all of that, it travels within the Clarke Belt, named after that great science Fiction author, Arthur C.

I wasn't happy with the last dish. I had to create a texture to make the dish look paraboloid but for this one I have used rings instead.
It uses the [Ripple] animation option.
The satellite image also uses the [Ripple] option.
It also uses (as does most of my X3D work) an invisible 'sizing frame' to keep each object in the correct position relative to each other.
The solar panels uses a texture which I created in Xara PGD
