Method Detail

getGraph

java.lang.Object getGraph()

getLightsCount

int getLightsCount()

Returns the number of light in this scene.

Returns:

number of scene lights

getShadeablesCount

int getShadeablesCount()

Returns the number of shadeable (visible) objects in the scene.

Returns:

number of shadeable objects

getStamp

int getStamp()

Returns a modification stamp for the scene graph. Each modification increments the value, so that the test whether some modification occured can be simply performed on values of the stamp.

Returns:

a stamp for the whole graph

traversSceneLights

void traversSceneLights(RTSceneVisitor visitor)

Provides an access to all light objects in this scene. For each light object the methode RTSceneVisitor.visitObject(RTObject object) is called.

Parameters:

visitor - a visitor object that can perform a proccessing with a concrete scene light.

traversSceneObjects

void traversSceneObjects(RTSceneVisitor visitor)

Provides an access to all objects in this scene. For each object the methode RTSceneVisitor.visitObject(RTObject object) is called.

Parameters:

visitor - a visitor object that can perform a proccessing with a concrete scene object.
