Member Function Documentation

◆ getBoundingBox()

const BoundingBoxMinimal & getBoundingBox ( ) const

Returns: The bounding box that has been calculated from the supplied scene during the last call to process().

Precondition: The process() function must have been invoked.

◆ isEmpty()

bool isEmpty ( ) const

Returns: true of the bounding box is empty, false otherwise.

◆ preVisits()

bool preVisits ( Scene & scene )

overrideprotectedvirtual

Parameters

scene The scene being visited.

This function should only ever be called by process(). Client code should not call it directly. The default implementation performs a check on this condition and returns true if the function is being called within a call to process(), or false otherwise. The default implementation performs no other action.

Subclasses may wish to provide their own implementation for preVisits() in order to set up their own internal data structures. They are not required to call this base class implementation if they do so.

Reimplemented from SceneItemProcessor.

◆ visitImpl()

bool visitImpl ( MeshModelInstance & modelInstance )

overrideprotectedvirtual

Parameters

modelInstance The model to visit.

Note: This function will only be called if modelInstance is enabled (this is controlled by the visit(MeshModelInstance&) function which is the only place visitImpl(MeshModelInstance&) should be called from).

The default implementation does nothing. Most subclasses will override this function.

Reimplemented from SceneProcessor.
