Facial Setup (Tommy)

(last update: 5/27/06)

SKELETONS:

jaw (open,left,right,forward,back)
The jaw will employ a two-bone skeleton, with one bone oriented down from the mandible hinge to the lower corner of the jaw, and the next bone oriented forward from there to the front of the jaw. The jaw can be rotated and translated from one or both of these bones for a variety of behaviors (rotational and translational jaw opening, translational jaw grinding, etc). Secondary clusters will automatically compensate for any artifacts or short-comings associated with the primary jaw envelope. The primary jaw envelope encompasses the entire jaw, with falloff extending up to the eye socket and tissue reflection into the neck.

tongue (full transformations, incl. scale)
The tongue will employ a multi-bone skeleton that is  parented to the jaw skeleton. The tongue will have a full range of motion, including scale (bone stretch).


BLENDSHAPES:

smile (L_smile, R_smile)
A broad, closed-mouth smile including dimples and creases. Affected region extends down into chin and up into cheeks, but should not affect upper cheeks near the eyes (this will be handled by a separate shape). Nostrils are affected a little. Mouth corners move back as well as up, and the mouth moves up vertically a bit. Lips stretch thin over teeth. In animation, an open-mouth smile is achieved by the combination of the smile shape with the jaw envelope.

frown (L_frown, R_frown)
A deep, closed-mouth frown including dimples and creases. The conceptual (though not literal) opposite of the smile, with a similar affected region. Mouth corner movement is narrower than smile, but corners travel back as much as down. Less effect on middle of mouth than the smile. In animation, an open-mouth frown is achieved by the combination of this shape with the jaw envelope and other shapes.

grimace (L_grimace, R_grimace)
A closed mouth, broad lateral line with dimples. Affected region extends from just around/beneath the nose down into the chin, and sideways into the cheeks. The grimace shape also pulls towards the back and thins the lips.

pucker (L_pucker, R_pucker)
The conceptual (though not literal) opposite of the grimace. In the pucker shape, the lips pull together as though with a drawstring, closed and pulled forward a bit. Affected region is similar to grimace, with a little more affect on the chin (which moves downward a bit). Should combine with cheek suck shape.

blow (L_blow, R_blow)
An "oo" shape with tight corners. Should transition seamlessly as the pucker is dialed in while the blow is dialed out, and should combine with cheek suck shape.

lips sneer (L_upLipSneer, R_upLipSneer, L_loLipSneer, R_loLipSneer)
The upper lip moves up, relatively even across when both sides are dialed in. Main pulls are above the incisors, with the middle taken along for the ride. Should fall off nicely towards the corners and mix well with the smile, frown, grimace, pucker and nose flare. (Because the nose flare is a separate shape, the upper lip sneer shape should not affect the nose.) Creates a SH in combination with the lower lip sneer, an EE in combination with the lower lip sneer, smile & grimace, or an OO when combined with the lower lip sneer and pucker. - The lower lip moves down, relatively flat across when both sides are dialed in. The complement of the upper lip sneer shape, with a similar affected range (the chin is influenced on this shape).

lips curled (L_upLipCurl, R_upLipCurl, L_loLipCurl, R_loLipCurl)
The upper lip curls inward. Creates an EM in combination with the lower lip curl, lower lip up and upper lip down shapes. - The lower lip curls inward.  Can be used to produce the EF sound.

lips pursed (L_upLipPurse, R_upLipPurse, L_loLipPurse, R_loLipPurse)
The upper lip purses outward, as though stifling a sneeze (but does not affect nose). Pairs with the lower lip purse shape. The lip shapes should distinguish CH from EE when combined with the upper lip sneer, lower lip sneer and inward lip corner shapes. - The lower lip purses outward, as though pouting.

lips puffed (L_upLipPuff, R_upLipPuff, L_loLipPuff, R_loLipPuff)
The lips puffed with air.  Affects the nose and chin slightly, but does not affect the cheeks (which have their own shape). Should combine nicely with cheek and lower lip puffs.

lips pressed (L_lipPress, R_lipPress)
The lips compressed together. Tissue displacement affects mouth line, chin, and surrounding lower face. Influence on nose can be handled by dialing in the nose narrow shape. Creates an EM, and can be combined with puffed lips, etc.

lips up (L_cnrLipUp, C_upLipUp, C_loLipUp, R_cnrLipUp)
Regional utility shapes which draw the lips along the "Y" axis.  The "L" and "R" regions have compatible falloff, and can be dialed together or used as modifiers in isolation.

lips down (L_cnrLipDn, C_upLipDn, C_loLipDn, R_cnrLipDn)
Regional utility shapes which draw the lips along the "Y" axis.  The "L" and "R" regions have compatible falloff, and can be dialed together or used as modifiers in isolation.

lips left (L_cnrLipLt, C_upLipLt, C_loLipLt, R_cnrLipLt)
Regional utility shapes which draw the lips along the "X" axis. The "L" and "R" regions have compatible falloff, and can be dialed together or used as modifiers in isolation.

lips right (L_cnrLipRt, C_upLipRt, C_loLipRt, R_cnrLipRt)
Regional utility shapes which draw the lips along the "X" axis. The "L" and "R" regions have compatible falloff, and can be dialed together or used as modifiers in isolation.

lips forward (L_cnrLipFwd, C_upLipFwd, C_loLipFwd, R_cnrLipFwd)
Regional utility shapes which draw the lips along the "Z" axis.  The "L" and "R" regions have compatible falloff, and can be dialed together or used as modifiers in isolation.

lips back (L_cnrLipBk, C_upLipBk, C_loLipBk, R_cnrLipBk)
Regional utility shapes which draw the lips along the "Z" axis.  The "L" and "R" regions have compatible falloff, and can be dialed together or used as modifiers in isolation.

lips thickened (L_cnrLipThick, C_upLipThick, C_loLipThick, R_cnrLipThick)
Utility shapes which thicken the interior lip walls to keep them from looking too thin when the mouth is open. Can be dialed in all at once, or regionally. (We may choose to dial up to "1" as the default state.)

nose flared (L_noseFlare, R_noseFlare)
The nose scrunched up with nostrils flared open, with the lower bridge thickened a bit just above the nostrils and tip of nose influenced.  Affected region is focused around base and sides of nose, with falloff into the cheeks and upper lip (with a bit of tug above the incisors). Should work in conjunction with shapes such as upper lip sneer, smile, frown, etc. Sneer creases should exist on same vertex rows as smile and frown creases.
 
nose narrowed (L_noseNarrow, R_noseNarrow)
The nostrils narrowed a bit as though trying to suppress a sneeze, with the nose pulled down slightly and the lower bridge thinned a little just above the nostrils. Affected region is similar to the nose flare. Used in conjunction with downward lip and cheek shapes.
 
cheek up (L_cheekUp, R_cheekUp)
The upper region of the cheek pushed upward.  Should encroach on the eye region a bit.  Works as a utility with other shapes - primarily the smile, nose flare and squint.

cheek down (L_cheekDn, R_cheekDn)
The upper region of the cheek drawn downward, as though hanging from the bone of the eye socket (conceptual opposite of the cheek up).  Works as a utility with other shapes, primarily the frown.

cheek sucked (L_cheekSuck, R_cheekSuck)
The cheeks sucked inward, as when tasting something extremely sour. Underlying cheekbone and jawbone integrity is maintained. Should combine with pucker and blow shapes.

cheek puffed (L_cheekPuff, R_cheekPuff)
The cheeks puffed outward.  Puff slightly obscures cheekbone and jawbone structure. Should combine nicely with upper and lower lip puffs.

eyelids closed (L_lidClose, R_lidClose)
The eyelids closed.  In the case of Tommy, intermediary blends may not be required to clear the eyeball curvature.

eyelids squeezed (L_lidSqueeze, R_lidSqueeze)
The eyelids compressed, with some lateral squeezing below the eyes and on the sides.  Eyelid tissue pushes forward in the compression.

eyelids wide (L_lidWide, R_lidWide)
The eyes wide open, as in shock. (The brows are not affected.)

squint (L_squint, R_squint)
Area of influence is outside and around the eye - with emphasis on outside edge where upper and lower lids meet, propagating into the side of the face and the cheek. The squint shape raises the lower lid somewhat, tugs on the upper, and pulls the outer areas of the eye in towards it (these should look as though traveling over a surface). Should combine well with smiling and enraged expressions.

low lid arc (L_lowLidArc, R_lowLidArc)
The lower eyelid arcin upward. No bearing in "reality" but useful to sweeten certain expressions.

inner brow up (L_inBrowUp, R_inBrowUp)
The inner brow up. The shape is strongest near the middle of the brow, tapering off in all directions, and should be almost the inverse of the outer brow down shape. Points pull out from under the brow ridge to give the effect of skin moving over bone. Does not affect the eyelids. The inner brow shapes should mix nicely with the outer brow shapes for overall brow control producing happy, sad, anger, surprise, etc.

inner brow down (L_inBrowDn, R_inBrowDn)
The inner brow down. The conceptual (and almost literal) opposite of the inner brow up shape. Points pull under the brow ridge to give the effect of skin moving over bone. Does not affect the eyelids. The inner brow shapes should mix nicely with the outer brow shapes for overall brow control producing happy, sad, anger, surprise, etc.

outer brow up (L_outBrowUp, R_outBrowUp)
The outer brow up. The shape is over the ridge of the brow near the temple, tapering off in all directions. Vertical influence can reach the hairline. As with inner brow shapes, pay attention to appearance of skin over bone. Should mix nicely with the inner brow shapes for overall brow control producing happy, sad, anger, surprise, etc.

outer brow down (L_outBrowDn, R_outBrowDn)
The outer brow down. The conceptual (and almost literal) opposite of the outer brow up shape. As with the inner brow down shape, keep area underneath the brow ridge looking plump. Should mix nicely with the inner brow shapes for overall brow control producing happy, sad, anger, surprise, etc.

furrow (L_furrow, R_furrow)
The brow squeezed together, forming vertical furrow lines. Affected area is about the same laterally as that of the inner brow shapes, but not as high vertically. Should mix nicely with the other brow shapes.

temple in (L_templeIn, R_templeIn)
The temples draw inward, such as when the jaw moves.

temple out (L_templeOut, R_templeOut)
The temples bulge outward, such as when the jaw is clenched.
 
neck tensed (L_neckTense, R_neckTense)
The neck tendons tensed and protruding under exertion, such as when extremely angry.
 
jaw clenched (L_clench, R_clench)
The rear corner of the jaw bulging under pressure when the jaw is clenched in the closed position.
 
chin up (chinUp)
The flesh of the chin, tugged upward.
 
chin down (chinDn)
The flesh of the chin, tugged downward.


CLUSTERS:

eye (translate)
A cluster will encompass each overall eye region, with falloff.

eyelid (rotate)
A cluster tied to the movement of the eyeballs will impart a bit of eyelid drag, with falloff.

ear (translate)
A cluster will encompass each overall ear region, with falloff.

lower face (translate)
A cluster will encompass the overall lower face region (including the nose), with falloff.

nose (translate)
A cluster will encompass the overall nose region (centered on the protrusion), with falloff.

cheek (translate)
A cluster will encompass each overall cheek region, with falloff.

mouth (translate)
A cluster will encompass the overall mouth region (from just under the nose to just above the chin), with fall off. There will also be four additional mouth clusters at the region of the left corner, right corner, upper center and lower center.

lips (translate)
Each vertical vertex row of the lips (upper & lower) will be placed in a separate cluster. These can be used for fine adjustments, as well as for "unzipping" the mouth if a "sticky lip" behavior is required as the jaw opens.

chin (translate)
A cluster will encompass the chin region, with falloff to the notch beneath the lower lip.


WIRES:

head (translate)
The head will feature a couple wires: an overall head wire up through the center mass, and a hair wire which runs front-to-back.


SCULPT DEFORMERS:

swallow (all transformations)
A sculpt deformer inside the front of the neck to simulate the Adam's apple during swallowing, etc.
