Improve atmosphere #1064

Show atmosphere on the globe, not just the sky
Maybe show atmosphere on objects

Reading (old to new)

Rendering Outdoor Light Scattering in Real Time - old, but good intro material
Accurate Atmospheric Scattering in GPU Gems 2 - what Cesium does now (sky only). Perhaps do ground atmosphere as a separate pass over the central body?
Real-Time Rendering of Planets with Atmospheres - too big to stream?
Precomputed Atmospheric Scattering
An Approximation to the Chapman Grazing-Incidence Function for Atmospheric Scattering in GPU Pro 3

Lots of stuff on vterrain.org.

Side note: The moon currently obstructs the atmosphere

hpinkos commented 9 years ago

Also, the atmosphere doesn't render on some mobile devices. Reported on the forum: https://groups.google.com/forum/#!topic/cesium-dev/Z3KJnMCkSSc

3141 has weblreport for my phone (which doesn't show atmosphere). My Nexus 9 tablet shows the atmosphere fine.

I have realised of the same issue as https://github.com/AnalyticalGraphicsInc/cesium/issues/1064#issuecomment-148201181 looking at the globe from afar. When the Moon is behind the Earth, the Moon is rendered below the Earth, but on top of the atmosphere.

pjm4 commented 8 years ago

@jmgomezpoveda et al you can see this issue, where the moon appears in front of the atmosphere, but behind the earth, more pronounced when the size of the moon is increased with the following code snippet:

var radius = Cesium.Math.LUNAR_RADIUS * 10;
viewer.scene.moon = new Cesium.Moon({
    ellipsoid : new Cesium.Ellipsoid(radius, radius, radius)
});

Closing this after recent atmosphere improvements we've made. Going forward, we'll track specific enhancement ideas in new issues.
