第四周作業

今天目標: 碰撞偵測

環境設定好
LeapMotion裝起來 (Software, Leap Developer Kit)
用新版 Processing 來 Import Library 
安裝library
Leap Motion for Processing
bRigid  
ComputationalGeometry
SuperCollider

把  Leap Motion 範例的 e1_basic 的程式碼簡化
試著將簡化的 code 結合到 bRigid 的Terrain 範例中
會依照手指的座標產生新的東西掉下來

code:

import javax.vecmath.Vector3f;

import processing.core.PApplet;

import peasy.*;

import bRigid.*;

import de.voidplus.leapmotion.*;

LeapMotion leap;

PeasyCam cam;

BPhysics physics;

BObject rigid;

BTerrain terrain;

public void setup() {

  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);

  

  leap = new LeapMotion(this);

}

public void draw() {

  background(255);

  lights();

  rotateY(frameCount*.002f);

  for(Hand hand : leap.getHands()){

    hand.draw();

    

    

    for(Finger finger : hand.getFingers()){

      

      // Basics

      finger.draw();

      PVector leapPos = finger.getPosition();

  if (frameCount%2==0) {

    Vector3f pos = new Vector3f(leapPos.x/10-90, -30 , leapPos. y/10-90);

    //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);

  }

}
