// bRigid provides classes for an easier handling of jBullet in Processing. bRigid is thought as a kind of Processing port for the bullet physics simulation library written in C++. // This library allows the interaction of rigid bodies in 3D. Geometry/ Shapes are build with Processing PShape Class, for convinient display and export (c) 2013 Daniel Köhler, daniel@lab-eds.org //here: build a TriangleMesh and use it as "Terrain" 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()) { PVector hand_position = hand.getPosition(); if (frameCount%2==0) { Vector3f pos = new Vector3f(hand_position.x/5-90, -30, hand_position.y/5-90); //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); } }
