Modifying the script to work with facial animation

[maincake]

Hello,

I'm performing a facial animation using Tracking data, and I need to rigg a face using the tracking data that has been transformed into Locators.

Basically a script that take the Locators(that contain the animation), and transform them into joints, so they can be used to attach to the normal face model and animate the character's face. 

// This script will select a vert on a model and add an emitter and a marker to the object.
// This will take a selection of verts and make and turn it into a string/list. -fl flag is added to deal with the verts, this way it will seperate everything out so we can do an operation on each vert.

string $sel[] = ls -fl -sl;
string $obj;

// This will set up a loop for us to use.

for ($obj in $sel)

{
select $obj;

// Rename strings

string $emitterRename = ($obj +"emitter");
string $normalConstraintRename = ($obj +"normConstraint");

print $emitterRename;
print $normalConstraintRename;

// Make the emitter

emitter -type omni -r 100 -sro 0 -nuv 0 -cye none -cyi 1 -spd 1 -srn 0 -nsp 1 -tsp 0 -mxd 0 -mnd 0 -dx 1 -dy 0 -dz 0 -sp 0 -n emitter;
HideSelectedObjects;

// Make the nurbs spheres
// If you want to change the size of the spheres, change the number after -r

sphere -p 0 0 0 -ax 0 1 0 -ssw 0 -esw 360 -r .1 -d 3 -ut 0 -tol 0.01 -s 2 -nsp 2 -ch 1 -n marker_CTRL;objectMoveCommand;
setDisplaySmoothness 3;
DeleteHistory;

// Create a joint for each marker. These Joints will follow the markers due to the parent constraint we are about to make.
// If you want to change the joint radius, change the number after "joint.radius"

joint -p 0 0 0 -n joint_ -rad .05;

select -cl ;

// objExists will return true or false (1 or 0), so you can use it multiple ways. 

int $objTest = objExists rootJointWorld ; 

// If that object exists, it will return 1 (true), so then you could say something like: 

if($objTest == 1) { 
print "It Exists!" ; 
} 
else {
// This will create a joint at the world orient, all other joints will be parented to this joint.
// -n will allow us to name the joint, and -rad will let us set the radius for the joint.
joint -p 0 0 0 -n rootJointWorld -rad .2;
}

select -r joint_ rootJointWorld;
parent;

select -r marker_CTRL joint_;
parentConstraint -weight 1;

select -cl ;

select -r joint_;

rename "joint_" "joint_000";

// Create marker group

select -r marker_CTRL;
group -em -n marker_CTRL_Group; xform -os -piv 0 0 0 ;

// Parent the marker to the group

select -r marker_CTRL marker_CTRL_Group;
parent;

// Point constrain the marker group to the emitter

select -r "emitter" marker_CTRL_Group;
pointConstraint -weight 1;

// Normal constrain the marker group to the object

select -r $obj marker_CTRL_Group;
normalConstraint -weight 1 -aimVector 0 1 0 -upVector 0 1 0 -worldUpType "vector" -worldUpVector 0 1 0 -n $normalConstraintRename;

// Rename the parts

rename "marker_CTRL" "marker_CTRL_";
rename "emitter" $emitterRename;
rename "marker_CTRL_Group" "marker_CTRL_Group_";

//end of the loop

}

// Group the markers

select -r "marker_CTRL_Group_*";
group -n marker_CTRL_GROUPS; xform -os -piv 0 0 0;

// Groups all the emitters into a set.

select -r -ne "emitterSet*";
$createSetResult = sets -name emitterSets\_ALL;
select -cl ;
