SKELETOID V. I
Skeletoid is a simplified human sleleton, created as an Imagine
Object File for animation on low-end machines which mayn't
handle high-priced, memory-intensive clip-objects. Skeletoid
simulates the human skeleton with the least possible number of
points and polygons.
Notice that Skeletoid isn't really an OBJECT, but is a GROUP of
objects, with the axis of each individual bone-object placed for
effective movement.
Note that his spinal column has been reduced to three segments
rather than numerous vertebrae, to save memory.
He also lacks individual teeth ( real memory gobblers! ).
Regarding Skeletoid's movements:
The best instructor on the action of the various joints is your
own body - but here are some tips:
Most of the skull's freedom of movement - side to side and up
and down - occurs right where the skull joins the spine.
Great freedom of movement is imparted to the upper
appendages (arms) by the scapula's (shoulder blade's) ability to
SLIDE AROUND AND ROTATE on the back of the rib cage.
Watch a naked friend move his/her arms around and see.
Note that the elbow is pretty much a simple hinge which bends
only one way - so also, the knee.
So ALSO, the foot. Standing, point your toe straight ahead and
then turn it out to point to one side with both hands on your
thigh. You will observe that almost all of the movement is at
the HIP!
Shoulder and hip joints are ball and socket arrangements with
considerable (but not unlimited) freedom of movement.
In real life the two bones of the lower leg are fixed in relation to
one another UNLIKE the two bones of the forearm.
The radius and ulna of the forearm are responsible for our
ability to use doorknobs and screwdrivers. The ulna is big on
the elbow-end and makes a hinge joint with the upper arm. The
radius is big on the wrist-end where it makes a hinge joint with
the hand. It is the ability of the radius to TWIST around the
ulna (sort of) that imparts what we (incorrecltly) refer to as the
"twist of the wrist". Try it while you PALPATE (feel) your
forearm with your other hand and you'll see. But don't make
yourself crazy making Skeletoid's forearms work this
realistically.
HELL'S BELLS! You may want to make all his bones fly apart
and come back together all mixed up!
I HAD FUN animating his toothless jaws AS IF THEY WERE
LIPS! REALLY CREEPY!!!
Stick eyeballs in him! Put him in a suit or just in sandwich
boards! HELL, put him in a barrel to cover his nakedness!
I'M GOING TO DRESS HIM UP LIKE SANTA CLAUSE AND
SEND HIM TO YOUR HOUSE TONIGHT!
HOW DO YOU KILL SOMETHING THAT'S
ALREADY DEAD?
Uh, er, sorry about that...
