1.Voxxlr
用平板掃描，可掃描大物件，製作3D影像
http://www.voxxlr.com/

2.KinectFusion

3. Time-of-Flight Camera

利用紅外線反射掃描，以每一個像素掃描

4.點線面掃描
(點)
利用機械手臂掃描
優點:較精準
缺點:較耗時、沒效率

(線)雷射光掃描
利用雷射光掃描曲線再組合
缺點:需要掃描很多面

(面)轉物體360度掃描

把3D兔子變成樂高積木

void mouseDragged(){

  angleX+=0.01*(mouseX-pmouseX);

  angleY+=0.01*(mouseY-pmouseY);

}

在程式碼內按Ctrl+K開啟火箭檔案資料夾
將三個檔案都拉進視窗

火箭

可根據滑鼠移動火箭方向

PShape bunny;

void setup(){
  size(400,400,P3D);
  bunny = loadShape("rocket.obj");
}
void draw(){
background(255,0,0);
lights();
translate(width/2,height/2);
rotateX(radians(mouseY));
rotateY(radians(mouseX));
shape(bunny,0,0);

}
