How to use

calcHorizontallySpeed

method

in

kendzi.jogl.camera.SimpleMoveAnimator

public void updateState() {
  double time = System.currentTimeMillis() / 1000d;
  double dt = time - lastTime;
  lastTime = time;
  vf = calcForwardSpeed(vf, dt, time);
  vs = calcSideSpeed(vs, dt, time);
  vu = calcUpSpeed(vu, dt, time);
  wh = calcHorizontallySpeed(wh, dt, time);
  Vector3d speed = new Vector3d(vf, vu, vs);
  speed = PointUtil.rotateZ3d(speed, angle.z);
  speed = PointUtil.rotateY3d(speed, angle.y);
  Vector3d dx = speed;
  dx.scale(dt);
  point.add(dx);
  Vector3d angleSpeed = new Vector3d(0, wh, 0);
  Vector3d dOmega = angleSpeed;
  dOmega.scale(dt);
  angle.add(dOmega);
