Face assignment

Miko

In my first assignment I really wanted to incorporate some form of animation. I decided to focus on blinking eyes. I used arc() function to draw arcs and changed their start points as well as the endpoints with respect to other parts of the eye. I decided to split the animation into 3 parts: the eyelid, the iris and the pupil. The eyelid and the iris animate at the same intervals, but the iris needed a small adjustment, as the arc length of a circle did not correspond directly to that of an ellipse of the eyelid. The last part, the pupil, comes into play only when the eyelid is almost closed.

float eyelidPosition = 40;
float irisPosition = 40;
float pupilPosition = 5;
float speed = 0.3;
int skinColor = #FEB186;
int mouthColor = #C18E74;

void setup() {
size(640, 360);
background(255);
}

void draw() {
background(255);
drawFace(200, 200);
}

void drawEye(int x, int y) {
//EyeShape
ellipse(x, y, 60, 40);

//Eyelid
fill(skinColor);
arc(x, y, 60, 40, PI, 2*PI);
fill(255);

//Eyelid animation
arc(x, y, 60, eyelidPosition, PI, TWO_PI);
arc(x, y, 40, 40, -irisPosition*PI/80, PI+irisPosition*PI/80);

//Pupil
fill(0);
arc(x, y, 5, 5, -pupilPosition*PI/5, PI+pupilPosition*PI/5);
fill(255);

eyelidPosition = eyelidPosition+speed;
irisPosition = eyelidPosition-3*PI;

if (eyelidPosition < 5) {
pupilPosition = pupilPosition+speed;
}
if (eyelidPosition < 0) {
delay(int(random(7)*100));
eyelidPosition=0;
speed=random(0.1,0.5);
} else if (eyelidPosition > 40) {
delay(int(random(5)*1000));
eyelidPosition=40;
speed=-random(0.1,0.5);
}
if (irisPosition < 0) {
irisPosition=0;
}
if (pupilPosition < 0) {
pupilPosition=0;
}
}

void drawSmile(int x, int y) {
fill(mouthColor);
arc(x, y, 150, 60, 0, PI);
arc(x, y, 150, 20, 0, PI);
fill(255);
}

void drawFace(int x, int y) {
fill(skinColor);
ellipse(x, y, 200, 250);
fill(255);
drawSmile(x, y+50);
drawEye(x-50, y-30);
drawEye(x+50, y-30);
}
