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.
