期中組作品想做大概:

今天課程開始一樣先到 leapmotion.com/setup 下載軟體, 然後Processing下載 LeapMotion for Processing的library
接下來我們要學如何利用2手,來做互動的調色盤 (上週教 Visualizer)
程式碼:
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);
}
}
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);
}
}
下圖為五根手指頭有分別不同的顏色出來的圖:
接下來讓線變3D立體
程式碼:
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;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;
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++){
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);
}
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);
}
}
下圖為3D圖截圖:
接下來要做左手右手的搭配所用出來的圖:
程式碼:
import de.voidplus.leapmotion.*;//LeapMotion標頭檔
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+500, 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);
}
}
}
}
這次課程的心得:
覺得每次上這個課都很有趣,雖然跟得比較慢,但希望能做出好玩又有趣的遊戲~
