1.先改寫上周的程式碼,把五隻手指頭都可以偵測出來
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);
}
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);
}
}
2.畫出3d的圖
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;}
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);
}
}
3.畫出旋轉網格,畫出3D的樣子
import de.voidplus.leapmotion.*;
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);
}
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;
}
for (Hand hand : leap.getHands ()) {
for (Finger finger : hand.getFingers ()) {
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;
if (f==1)println(now);
}
}
translate(width/2, height/2);
rotateY(radians(frameCount/4.0));
translate(-width/2, -height/2, 0);
for (int f=0; f<5; f++) {
for (int i=1; i<10; 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)
for (int j=0; j<480; j+=20) {
noFill();
rect(i, j, 20, 20);
}
}
4.抓取雙手,並顯示一個是橢圓一個是長方形
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);
}
}
}
5.調色盤
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);
}
}
}
}
期中作業初步構想(與冠中一組):
利用兩台Leap Motion做連線遊戲,右手控制方向,左手發射,使兩人可以一起連線做合作遊戲。
