Flower Rig

Flower Rig

This project has been created to demonstrate how to set up an IK/FK switch for a simple character. This project also introduces some scripting and SeExpressions for the Petals.

Demonstrating the IK / FK Switch that happens on this rig

Demonstrating how some simple SeExpressions can bring a rig to life

Basic structure for the expression applied to each petal joint

// Expressions
// 1. Create a speed control attribute
// 2. on each master petal joint add these lines for rotateZ
petal01_JNT_01.rotateZ = 3 * sin(frame/FLOWER.speed);
petal01_JNT_01.rotateY = .4 * cos(frame/FLOWER.speed);

Simple script to speed up the rigging process:

// 1. select parent joint, select your child joint
// 1a. make a list for each joint in a petal
// 1b. separate the list into a parent list (first 4), and the children (second 4)
// 2. make the rotation connection
// 3. do this string 

$petalParents[] = {"petalArm05_01", "petalArm05_02", "petalArm05_03", "petalArm05_04"};
$petalChildren[] = {"petalArm05_02", "petalArm05_03", "petalArm05_04", "petalArm05_05"};

global proc jointRotation(string $myParent, string $myChild){ // this function connects the rotation of 2 joints 
    connectAttr -f ($myParent + ".rotate") ($myChild + ".rotate");
}

int $i;  // variable to iterate through the list
for ($i = 0; $i < 4; $i++) {
     jointRotation($petalParents[$i], $petalChildren[$i]);
}

Some fun things I played around with using some simple scripts.
These have nothing to do with the project.
Trying different things while helping students
Quite interesting to look at.
