SceneGraphObject::OID appendLight (  LightSource *  light  )  [inherited]

Appends a light source to the scene. Parameters: light  appended light source Definition at line 53 of file Scene.cc. References Scene::_haveLight, Scene::_lastOID, and Scene::_sceneGraph. Referenced by CornellBox::_build_lights(), SphereFlake::_create_lights(), and FractalMount::_create_lights().

SceneGraphObject::OID appendModel (  Parser &  parser, const Matrix4 *  m = NULL )  [inherited]

Appends model to the scene. Parameters: parser  parser of the model m  transfoprmation matrix of the model Definition at line 7 of file Scene.cc. References Scene::_lastOID, and Scene::_sceneGraph.

SceneGraphObject::OID appendObject (  SceneGraphObject *  primitive  )  [inherited]

Appends single object to the scene. Parameters: primitive  appended object Definition at line 32 of file Scene.cc. References Scene::_lastOID, and Scene::_sceneGraph. Referenced by CornellBox::_build_sphere_flake(), CornellBox::_build_walls(), SphereFlake::_create_spheres(), FractalMount::_create_spheres(), CornellBox::addCrystalicSphere(), CornellBox::addMirrorSphere(), and SphereFlake::SphereFlake().

void build (  void   )  [inline, inherited]

Prepares the scene for manipulation. There is no guarantee that the scene is realy created until the build() method is called. After the build() call the scene is created. Nevertheless, you _can_ still append additional primitives and/or models. Definition at line 65 of file Scene.h. Referenced by FractalMount::FractalMount(), and SphereFlake::SphereFlake().

bool haveLight (  void   )  const [inline, inherited]

Returns: true if the scene has light, false otherwise Definition at line 70 of file Scene.h.

Returns: root of the scene graph Definition at line 75 of file Scene.h.
