Examples of ca.eandb.jmist.framework.Lens.sample()

ca.eandb.jmist.framework.Lens.sample()
Creates the terminal EyeNode for use by path-integration based rendering algorithms. @param p The point on the image plane in normalized device coordinates(must fall within {@code Box2.UNIT}). @param pathInfo The PathInfo describing the context inwhich the path is being generated. @param ru The first random variable (must be in [0, 1]). @param rv The second random variable (must be in [0, 1]). @param rj The third random variable (must be in [0, 1]). @return A new EyeNode.


    if (newEyeTail == null && m1 > 0) {
      PathInfo pi = x.getPathInfo();
      Lens lens = pi.getScene().getLens();
      Point2 p = RandomUtil.canonical2(rnd);
      newEyeTail = lens.sample(p, pi, rnd.next(), rnd.next(), rnd.next());
      m1--;
    }
    while (m1-- > 0) {
      newEyeTail = newEyeTail.expand(rnd.next(), rnd.next(), rnd.next());
      if (newEyeTail == null || newEyeTail.isAtInfinity()) {
