中作品是什麼
2. 老師教如何利用2手,來做互動的調色盤 (上週教 Visualizer)
3. 先到 leapmotion.com/setup 下載軟體, 然後Processing下
載 LeapMotion for Processing的library
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); }}

第一節課
複習上星期的進度
手指畫畫變3d
利用Leap Motion偵測五隻手指,畫出有殘影的線
實際演示場景
