示例1: spawnSubBranches

void Branch::spawnSubBranches(const int level, const double length, const double thickness)
{
  if (level == recursiveDepth) return;

  // Spawn subbranches (make more as we get smaller)
  int numBranches = rand(0.2, 0.8, (level == 0 ? 2 : level) * initialBranches);
  for (int i = 0; i < numBranches; i++) {
    add_child(new Branch("SubBranch", level + 1,
                         nextThickness(thickness, level),
                         nextLength(length, level)));
    totalBranches++;
  }

  // Tree branches seem to split in two at the ends so simulate that.

  add_child(new Branch("SplitBranch", level + 1, nextThickness(thickness, level), 
                       nextLength(length, level), length, -30.0, 0.0));
  add_child(new Branch("SplitBranch", level + 1, nextThickness(thickness, level), 
                       nextLength(length, level), length, 30.0, 0.0));
  // Two branches coming out of the top looks a little weird so add a sphere.
  Sphere* p_sphere = new Sphere();
  GeometryNode* sphere = new GeometryNode("BranchTop", p_sphere);
  sphere->set_material(&wood);

  sphere->translate(Vector3D(0.0, 0.0, length));
  sphere->scale(Vector3D(thickness, thickness, thickness));

  add_child(sphere);

  totalBranches += 3;
}

示例2: SceneNode

Leaf::Leaf(const std::string& name, const double branchThickness, const double branchLength)
  : SceneNode(name)
{
  ImagePrimitive* i_leaf = new ImagePrimitive();
  GeometryNode* leaf = new GeometryNode("Leaf", i_leaf);
  leaf->set_material(&leafTexture);

  double upDist = rand(1.0/3.0, 1.0, branchLength);
  double zAngle = rand(0.0, 1.0, 360.0);

  double diagonalDist = branchThickness + sqrt(2.0) - 0.25;
  double xyDist = -diagonalDist * sqrt(2.0) / 2.0;

  leaf->rotate('z', zAngle); 
  leaf->translate(Vector3D(xyDist, xyDist, upDist));

  add_child(leaf);
}
