期中作品:視力檢查
1.先到Leap Motion網站安裝軟體 Processing下載LeapMotion for Processing的library
2.複習上星期教的程式
import de.voidplus.leapmotion.*; //LeapMotion標頭檔
LeapMotion leap;
PVector [][] pt = new PVector[5][50];
//PVector pt1,pt2,pt3,pt4,pt5,pt6,pt7,pt8,pt9,pt10;
void setup() {
size(640, 480, P3D);
colorMode(HSB, 100);
for (int f=0; f<5; f++)
for (int i=0; i<50; i++)
pt[f][i] = new PVector(0, 0, 0);
leap = new LeapMotion(this); //LeapMotion起始值
}
void draw() {
background(0);
//stroke(48,191,153);
stroke(#30BF99);
for (int f=0; f<5; f++)
for (int i=49; i>0; i--) {
pt[f][i].x=pt[f][i-1].x;
pt[f][i].y=pt[f][i-1].y;
}
for (Hand hand : leap.getHands ()) { //抓取手
for (Finger finger : hand.getFingers ()) { //抓取手指
int f=finger.getType();
PVector now = finger.getPosition();
pt[f][0].x = now.x;
pt[f][0].y = now.y;
}
}
for (int f=0; f<5; f++) {
stroke(f*20, 100, 100);
for (int i=1; i<10; i++)
line(pt[f][i].x, pt[f][i].y, pt[f][i].z, pt[f][i-1].x, pt[f][i-1].y, pt[f][i-1].z);
}
}
3.把上週程式改寫成可3D畫線
且對y軸做旋轉

import de.voidplus.leapmotion.*; //LeapMotion標頭檔
LeapMotion leap;
PVector [][] pt = new PVector[5][50];
void setup() {
size(640, 480, P3D);
colorMode(HSB, 100);
for (int f=0; f<5; f++)
for (int i=0; i<50; i++)
pt[f][i] = new PVector(0, 0, 0);
leap = new LeapMotion(this); //LeapMotion起始值
}
void draw() {
background(0);
stroke(#30BF99);
for (int f=0; f<5; f++)
for (int i=49; i>0; i--) {
pt[f][i].x=pt[f][i-1].x;
pt[f][i].y=pt[f][i-1].y;
pt[f][i].z=pt[f][i-1].z;
}
for (Hand hand : leap.getHands ()) { //抓取手
for (Finger finger : hand.getFingers ()) { //抓取手指
int f=finger.getType();
PVector now = finger.getPosition();
pt[f][0].x = now.x;
pt[f][0].y = now.y;
if (f==1)
println(now);
}
}
translate(width/2, height/2);
rotateY(radians(frameCount));
translate(-width/2, -height/2);
for (int f=0; f<5; f++) {
stroke(f*20, 100, 100);
for (int i=1; i<10; i++)
line(pt[f][i].x, pt[f][i].y, pt[f][i].z, pt[f][i-1].x, pt[f][i-1].y, pt[f][i-1].z);
}
}
第二節課
1.把剛剛的程式寫得更完整
且加上格子
import de.voidplus.leapmotion.*; //LeapMotion標頭檔
LeapMotion leap;
PVector [][] pt = new PVector[5][50];
void setup() {
size(640, 480, P3D);
colorMode(HSB, 100);
for (int f=0; f<5; f++)
for (int i=0; i<50; i++)
pt[f][i] = new PVector(0, 0, 0);
leap = new LeapMotion(this); //LeapMotion起始值
}
void draw() {
background(0);
stroke(#30BF99);
for (int f=0; f<5; f++)
for (int i=49; i>0; i--) {
pt[f][i].x=pt[f][i-1].x;
pt[f][i].y=pt[f][i-1].y;
pt[f][i].z=pt[f][i-1].z;
}
for (Hand hand : leap.getHands ()) { //抓取手
for (Finger finger : hand.getFingers ()) { //抓取手指
int f=finger.getType();
PVector now = finger.getPosition();
pt[f][0].x = now.x;
pt[f][0].y = now.y;
pt[f][0].z = now.z*2-90; //要自己試很多值
if (f==1)
println(now);
}
}
translate(width/2, height/2, 0);
rotateY(radians(frameCount/4.0)); //除4會轉慢一點
translate(-width/2, -height/2, 0);
for (int f=0; f<5; f++) {
for (int i=1; i<50; i++) {
stroke(f*20, 100, 100);
line(pt[f][i].x, pt[f][i].y, pt[f][i].z, pt[f][i-1].x, pt[f][i-1].y, pt[f][i-1].z);
}
}
stroke(60, 100, 100);
for (int i=0; i<640; i+=20) //畫格子
for (int j=0; j<480; j+=20) {
noFill();
rect(i, j, 20, 20);
}
左手是橢圓 右手是長方形
import de.voidplus.leapmotion.*;
LeapMotion leap;
void setup() {
size(640, 480, P3D);
leap = new LeapMotion(this);
}
void draw() {
background(255);
for (Hand hand : leap.getHands ()) {
PVector pos = hand.getPosition();
if (hand.isLeft()) {
ellipse(pos.x, pos.y, 200, 100);
} else if (hand.isRight()) {
rect(pos.x, pos.y, 10, 100);
}
}
}
第三節課
1.左手是調色盤 右手是長方形
import de.voidplus.leapmotion.*;
LeapMotion leap;
void setup() {
size(640, 480, P3D);
leap = new LeapMotion(this);
}
color nowColor=color(255, 0, 0);
PVector leftPos;
void draw() {
background(255);
for (Hand hand : leap.getHands ()) {
PVector pos = hand.getPosition();
if (hand.isLeft()) {
noFill(); ellipse(pos.x, pos.y, 200, 100);
fill(255, 0, 0); ellipse(pos.x+150, pos.y, 60, 50);
fill(255, 255, 0); ellipse(pos.x+120, pos.y-40, 60, 50);
fill(0, 255, 0); ellipse(pos.x+90, pos.y-60, 60, 50);
fill(0, 0, 255); ellipse(pos.x+30, pos.y-60, 60, 50);
fill(255, 0, 255); ellipse(pos.x-20, pos.y-60, 60, 50);
leftPos=pos;
} else if (hand.isRight()) {
fill(nowColor); rect(pos.x, pos.y, 10, 100);
println(leftPos);
println(pos);
if (dist(pos.x, pos.y, leftPos.x+120, leftPos.y-40)<30) {
nowColor=color(255, 255, 0);
}
}
}
}
