Somebody on one of the NASA sites was describing the surface of Europa
as probably looking like
"broken glass repaired by icy goo rising up from below". I took that
colorful comment as a POVray height_field challenge.
+-3 miles above
the surface of Europa. The distances between the light source, and the
planets as well as
planet diameters are to scale: 1 pov unit=100 kilometers. Rendered
with POVray 3.1
The shadows on Jupiter are cast by POVray, not painted on later. The
center shadow on Jupiter is the shadow of the moon we're standing on
(neato). It is night time from our viewing location but I imagine the
landscape would be pretty well lit by the light of a full Jupiter.
Ever been up to the Sierra Nevadas on a full moon lit night? It looks
like day time!
Thank you "SY" at news.povray.org for the following post...
"// Mean distance of the sun from Jupiter: 800E+6 km = 8000000E+2
units
// Sun's diameter is approx 1.4E6km = 1.4E4 = 14000 units
// use an area light to simulate the sun

The altitude of the camera above the surface of Europa is not to
scale.

The night sky is fairly close to being astronomically correct for the
