I found in Moray the term Inverse Kinematics, and I think I had already
heard this term before..
But I can't find in POVRAY's doc anything about Inverse Kinematics.
Could someone explain me what is it about ? and, if useful, where I can find
some explanations ?
Thanks

Povray itself has no internal support for inverse kinematics. However Moray
can use this technique using several of Pov's independent features to accomplish
inverse kinematics. You will find a good description of inverse kinematics
at this link: http://freespace.virgin.net/hugo.elias/ You will find that this
a powerful feature if you want to model something like the movement of human
arms, legs and similar multi-part movements where everything must act together
to perform an action.

As I understand it, IK in Moray is a kind of visual tool so it makes sense that
it appears in a GUI environment. It is anologous to attaching a camera to a
light source. A program made specifically for modeling can do that, so that the
camera moves with some object, such as a spotlight. However, a text document
won't monitor your changes to light sources and try to accomodate your camera
accordingly. In other words, many powerful features of visual modeling/design
programs (such as snaps) are made for your convenience but are absolutely
unnecessary in rendering. In the case of snaps, POV-ray isn't going to limit you
to increments of 0.1 or warn you if you entered a translation of 0.065, but
Moray might if you choose the snap feature.
