第四周上課內容

• 跑Rotate程式

• 簡易的LeapMotion

import de.voidplus.leapmotion.*;

LeapMotion leap;

void setup(){

  size(800,500,P3D);

  leap=new LeapMotion(this);

}

void draw()

{

  background(255);

  for(Hand hand:leap.getHands()){

  hand.draw();

  }

}

• 利用LEAPMOTION移動手部位置，在地形上投射方塊

• 讀入OBJ檔
• 
  

• 利用地形與自己的OBJ火箭結合

import saito.objloader.*;

OBJModel model;

PeasyCam cam;

BPhysics physics;

BObject rigid;

BTerrain terrain;

public void setup() {

  model = new OBJModel(this, "sh.obj", "relative", QUADS);

  size(1280, 720, P3D);

  frameRate(60);

  cam = new PeasyCam(this, 200);

  cam.pan(0, 50);

  cam.rotateX(.4f);

  physics = new BPhysics();

  physics.world.setGravity(new Vector3f(0, 40, 0));

  float height = 1.1f;

  //BTerrain(PApplet p, int tesselation, float height, int seed, Vector3f position, Vector3f scale) 

  terrain = new BTerrain(this, 110, height, 10, new Vector3f(), new Vector3f(2, 2, 2));

  physics.addBody(terrain);

  //create the first rigidBody as Sphere

  rigid = new BBox(this, 5, 1.0f, 10.0f, 1.0f);

}

public void draw() {

  background(255);

  lights();

  rotateY(frameCount*.002f);

  if (frameCount%2==0) {

    Vector3f pos = new Vector3f(random(-90, 90), -30, random(-90, 90));

    //reuse the rigidBody of the sphere for performance resons

    BObject r = new BObject(this, 5, rigid, pos, true);

    physics.addBody(r);

  }

  physics.update();

  terrain.display();

  for (int i =1;i<physics.rigidBodies.size();i++) {

    BObject b = (BObject) physics.rigidBodies.get(i);

//    b.display(50, 50, 50);

    Vector3f pos = b.getPosition();

    pushMatrix();

    translate(pos.x, pos.y, pos.z);

    model.draw();

    popMatrix();

  }

}
