Making the Earth
Re: Making the Earth
Nice work.
Can look at latest images (couple of days ago) from Earth Polychromatic Imaging Camera:
http://epic.gsfc.nasa.gov/
To me it's simple: water IOR + roughness caused by waves (which is never constant, so much noise) ... so as long as it feels 'real'
Like in this 'closer' image:

Re: Making the Earth
Thanks Burnin
I totally agree with you about that, I will see if lower the IOR is enough, or if I'll add some roughness, I'm on other details, so maybe a render tomorrowwater IOR + roughness caused by waves
Re: Making the Earth
It's also reflected frontally: you can see the sun reflection in the middle of each band in this satellite view: https://worldview.earthdata.nasa.gov/?p ... 6455940633Pibuz wrote: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
for tweaking match the highlight width, not its length obviously.
e: thinking that an eventual diffraction might be considered for correction, but it's probably negligeable

Re: Making the Earth
Yes I believe ( not because I am convinced of it but because of real pictures and physics ) that we shyould see some reflections even on a frontal view, more or less depending on the weather in the area and such various parameters.
This a render I made with a lower IOR. But I think the texture map should need some modifications on the oceans.
CTZn Tu parles du parametre "aperture diffraction" ou bien d'autre chose ?
Are you talking about the "aperture diffraction" parameter or something else ?

Re: Making the Earth
Je parlais de l'amplification du reflet du soleil dans l'eau par l'optique du satellite, mais ignore cette remarque.
I was referring to the amplification of the sun's reflection by the sat optics in the photo, but you should dismiss that remark.

Rendering Glints on High-Resolution Normal-Mapped Specular Surfaces
this would be more than helpful here

Re: Making the Earth
Burnin, I didn't use normal maps for these renders

Re: Making the Earth
Mars is awesome!
Re: Making the Earth
Thank you Oscar
I am more satisfied with Mars also
