Constructor & Destructor Documentation

Scene::Scene ( )

Constructs an empty scene.

void Scene::addObject ( Object & o )

Adds an object to the scene.

Box Scene::boundingBox ( ) const

Returns the value of the bounding box property. This property is undefined unless boundingBox() has been called for this scene.

void Scene::clear ( )

Clears the scene.

void Scene::computeBoundingBox ( )

Recomputes the bounding box of the scene, as the bounding box of its objects.

const vector< Object > & Scene::objects ( ) const

Returns a constant reference (read-only) to the vector of objects forming the scene.

vector< Object > & Scene::objects ( )

Returns a reference to the vector of objects forming the scene. VAR

int Scene::selectedObject ( ) const

If an object is selected, returns the index of that selected object (from 0 to number of objects - 1). Otherwise returns -1.

void Scene::setSelectedObject ( int index )

Sets the selected object by indicating its index. Only one object can be seleted at any given time.

Parameters:

index is the position of the selected object in the vector of objects.
