畫出背景(藍色格子)然後旋轉,讓整體看起來有更加3D的感覺。
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; pt[f][i].z=pt[f][i-1].z;}
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; //guess ITD range
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<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);
}
}
//藍色格子的部分
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);
}
}
要做出一個簡易的手部操作調色盤,當leapmotion裝置偵測雙手時,左手呈現橢圓形(調色盤),右手呈現長方形棒子(調色盤),
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);
}
}
}
增加顏色盤
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);
}
}
}
}
