These
"Virtual Reality Moon Phases" were created from ray-traced
images of the Moon. A Clementine spacecraft mosaic of the lunar
surface was mapped onto a sphere, and scenes were rendered as a
virtual Sun "orbited" the Moon. The depiction of lunar
surface features suffers geometric distortion but the terminator is
correct with respect to the spherical Moon. (Current Phase of
the Moon Updates every 4 hours)
You can
view the phase of the Moon for any date and time [1800-2199 A.D].
