Making the Earth
Re: Making the Earth
Yes I get ity for the displacement, and I made a lot of tests, and I can say that everything respect aproximately good all the real scales, also the elevation, and here the atmosphere is really bigger than everything else, and nothing of the Earth or of the clouds displaces over the atmosphere... More ever, I had exactly the same problem before add any elevation/displacement/subdivision...
Also I had seen before, when I had set to much displacement, that if raises over the atmosphere, then you see what raises over, and nothing else

Re: Making the Earth
Hello,
Well approximately one year and a half later, I come back to explain a bit how this subject evolved.
After the last message I gived up a little about the athmosphere problem I faced. But I returned on it a few months ago and finally solved it:
The problem was in fact that when I scaled the atmosphere sphere to real scale (6451Km radius), I scaled the group containing the sphere, not the sphere itself. That is why the atmosphere appeared as dense as a physical surface, like there was no medium.
To solve the problem, nothing more simple than explode the group containing the sphere, and create a new group. So simple that I didn't think to it
Since 2014 I learned a lot about indigo, and finally creating an atmosphere isn't so much complicated at all if we know the basis, so thanks for all of your help and advices and also to the manual.
I come back with a new render of the Earth, because I recently updated the textures, elevations, clouds map with higher resolution. Amongst other details for other planets... Because I worked on most of the Solar system, not only Earth, but I will make another post about that later because I faced a few other interesting problems with this initiative
If there are any suggestions about the renderings, I'll take it

Hi
I think I can say that the lighting is diffused not focused.

Re: Making the Earth
What do you mean ?
Re: Making the Earth
HI
My humble opinion is that you should not see the light specular of the arrow, in favor of a more widespread.
Otherwise he seems to see a rubber ball.

Re: Making the Earth
I understand what you mean. But according to some NASA pictures, we can sea the sun reflecting on the oceans, from space
Here is an exemple
Edit: I've set an IOR of 1.3

Re: Making the Earth
Yes, from grazing angles I suppose.
In "frontal" view does it work the same way?
..I'm not saying your image is wrong: only...there's something strange going on with it

Maybe I should lower the IOR a bit to simulate the loss of brightness; Or add more bump to the Earth map maybe
I will make some other tests, but I'm sure I've seen a photo of the sun reflecting in a more frontal view, I will try to find this picture again too

Re: Making the Earth
^ Yeah, don't forget to put an enormous bird with a space helmet in Alaska for ultimate realism.
Re: Making the Earth
Eneen, NASA does more renderings than real pictures, and I'm pretty sure this one isn't a picture ( without concidering that bird as an argument of course )
Re: Making the Earth
You're right, it can be.
But this one is most probably picture:

Re: Making the Earth
Yes this is, according to their history, the second picture of Earth in its entirety; the other picture is from 1972.. This one is from 2015
And it's true that we can see some sun reflection but maybe a bit less than on my render

Re: Making the Earth
Hi
Specular reflections from the distant space are impossible.
In the image where you see the sunrise the distance is less, then it is a close-up, then there is the effect of the oblique light, so comparisons are do not make sense. I therefore believe that lowering the level of reflectivity (IOR) is a good choice.

Re: Making the Earth
Why would it be impossible from the distant space ? Here on the Earth the light reflects on the sea and is refracted through and partially dispersed into the atmosphere, then is send to the objective, that is why we see it, no matter of the distance; we would not see it only if the atmosphere absorbed it all wich is not the case in real life nor in the renderSpecular reflections from the distant space are impossible.
