第三週課程:Leap Motion偵測兩隻手
week03:Two Hands
第一節課(複習上星期並劃出3D空間)
1.下載Leap Motion 驅動程式並安裝
2.網路出點問題，用Proxy
Google設定 -> 變更Proxy -> LAN設定 -> 將Proxy伺服器打勾
-> 並輸入位址:proxy.mcu.edu.tw 連接阜:3128
3.複習上星期的進度
記得要將Processing下載 LeapMotion for Processing的library
(利用Leap Motion偵測五隻手指頭，畫出有殘影的線)
4.畫出3D空間
增加三行
translate(width/2,height/2); //將初始點移到中間
rotateY(radians(frameCount));//開始對Y軸旋轉
translate(-width/2,-height/2);//將初始點移到中間
程式碼
import de.voidplus.leapmotion.*;
LeapMotion leap;
PVector [][] p=new PVector[5][10];
void setup()
{
size(800,600,P3D);
for(int f=0;f<5;f++)
{
for(int i=0;i<10;i++){ p[f][i]=new PVector(0,0,0);}
}
leap = new LeapMotion(this);
colorMode(HSB,100);
}
void draw()
{
background(0);
for(int f=0;f<5;f++)
{
for(int i=5;i>0;i--){p[f][i].x=p[f][i-1].x;p[f][i].y=p[f][i-1].y;}
}
for(Hand hand : leap.getHands())
{
for(Finger finger : hand.getFingers())
{
int f=finger.getType();
PVector now =finger.getPosition();
p[f][0].x=now.x;
p[f][0].y=now.y;
}
}
translate(width/2,height/2); //將初始點移到中間
rotateY(radians(frameCount));//開始對Y軸旋轉
translate(-width/2,-height/2);//將初始點移到中間
for(int f=0;f<5;f++)
{
stroke(f*20,100,100);
for(int i=1;i<5;i++){line(p[f][i].x , p[f][i].y , p[f][i].z , p[f][i-1].x , p[f][i-1].y , p[f][i-1].z);}
}
}
第二節課(完成3D空間)
1.完成3D空間 並畫出方格來對比
增加
畫方格
stroke(60, 100, 100);
for (int i=0; i<800; i+=20)
{
for (int j=0; j<600; j+=20)
{
noFill();
rect(i, j, 20, 20);
}
}
寫出數值
if (f==1)println(now);
畫出z
p[f][0].z=now.z*2-100;
import de.voidplus.leapmotion.*;
LeapMotion leap;
PVector [][] p=new PVector[5][10];
void setup()
{
size(800, 600, P3D);
for (int f=0; f<5; f++)
{
for (int i=0; i<10; i++) {
p[f][i]=new PVector(0, 0, 0);
}
}
leap = new LeapMotion(this);
colorMode(HSB, 100);
}
void draw()
{
background(0);
for (int f=0; f<5; f++)
{
for (int i=9; i>0; i--) {
p[f][i].x=p[f][i-1].x;
p[f][i].y=p[f][i-1].y;
}
}
for (Hand hand : leap.getHands ())
{
for (Finger finger : hand.getFingers ())
{
int f=finger.getType();
PVector now =finger.getPosition();
p[f][0].x=now.x;
p[f][0].y=now.y;
if (f==1)println(now);
}
}
translate(width/2, height/2, 0);
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(p[f][i].x, p[f][i].y, p[f][i].z, p[f][i-1].x, p[f][i-1].y, p[f][i-1].z);
}
}
stroke(60, 100, 100);
for (int i=0; i<800; i+=20)
{
for (int j=0; j<600; j+=20)
{
noFill();
rect(i, j, 20, 20);
}
}
}

第三節課(做出調色盤)
1.偵測兩隻手並畫上橢圓跟方形
import de.voidplus.leapmotion.*;
LeapMotion leap;
void setup()
{
size(800, 600, P3D);
leap = new LeapMotion(this);
}
void draw()
{
background(0);
for (Hand hand : leap.getHands ())
{
PVector pos =hand.getPosition();
if(hand.isLeft()) //偵測左手
{
ellipse(pos.x,pos.y,200,100); //畫橢圓
}
else if(hand.isRight()) //偵測右手
{
rect(pos.x,pos.y,10,100); 橢圓
}
}
}
2.可以把調整畫筆顏色
增加初始值
eftpos=new PVector(0,0,0); //要記得給初始值，否則會當機
LeapMotion leap;
void setup()
{
size(800, 600, P3D);
leap = new LeapMotion(this);
leftpos=new PVector(0,0,0); //要記得給初始值，否則會當機
}
color nowc=color(255, 0, 0);
PVector leftpos;
void draw()
{
background(255);
for (Hand hand : leap.getHands ())
{
PVector pos =hand.getPosition();
if (hand.isLeft())
{
noFill(); //畫顏料
ellipse(pos.x, pos.y, 200, 100);
fill(255, 0, 0);
ellipse(pos.x+150, pos.y, 40, 40);
fill(255, 255, 0);
ellipse(pos.x+120, pos.y-40, 40, 40);
fill(0, 255, 0);
ellipse(pos.x+90, pos.y-60, 40, 40);
fill(0, 0, 255);
ellipse(pos.x+60, pos.y-60, 40, 40);
fill(255, 0, 255);
ellipse(pos.x+30, pos.y-60, 40, 40);
leftpos=pos;
} else if (hand.isRight())
{
fill(nowc);
rect(pos.x, pos.y, 10, 100);
println(leftpos);
println(pos);
if (dist(pos.x, pos.y, leftpos.x+120, leftpos.y-40)<30)
{
nowc=color(255, 255, 0);
}
}
}
}
