C3DCamera handles camera object. More...

Detailed Description

C3DCamera handles camera object.

GetFinalObject returns a camera model in order to display the camera itself. Camera node contains the transformation matrix of the camera, that can be use to display this object.
Camera node matrix is the invert of the LookAt matrix (which can be used to position the scene in the front of camera).

	Attach scene and update guid for camera and its displayable.

virtual bool	IsFinalObject () const

virtual C3DBaseObject *	GetFinalObject (bool detach=false, bool computeIfNeeded=true)
	Returns the object itself or any kind of object. For example for a patch it can returns a C3DObject or a C3DPatch if the patch is not subdivided.

virtual unsigned int	GetChecksum (unsigned int checksumFlags=CHECKSUM_ALL) const
	Return a value that is a simple way to check if the geometry changed between two call to the method.

virtual void	Serialize (CXArchive &ar)

C3DScene *	GetScene () const
	Get the associated object scene.

BaseObjectID	GetObjectID () const
	Return the node GUID depending on the scene. If no scene defined, CGuidMgr::UNDEFINED_GUID is returned.

int	GetInstanceCount () const
	Return the instance count. If the count then this is a single object that is referenced only one time in the scene.

bool	IsInstanciated () const
	return true if several instance of the object exists. The C3DSceneNode that reference these instances can be retrieved using C3DScene::GetInstancesByID

unsigned int	GetCustomDataChecksum (unsigned int ignoreCustomID,...) const
	For object which are not geometric object, the checksum could be made on CustomData, and you can ignore some ID might be ignored if they content runtime value that does not reflect a change of the content. The list must be terminated by 0.

virtual bool	NeedUpdate () const

virtual bool	Update (C3DScene *scene, unsigned int updateMode)
	Information that have been invalidated are recomputed when calling this method.IsInstanciated.

virtual void	Invalidate (unsigned int objectInvalidationFlags, bool set=true)
	Notify that some information changed (combination of OBJECT_UPDATE_PROPERTIES invalidation flags) and invalidate related information, which will be updated in the Update call. The invalidated information is not destroyed until the next Update call.

virtual bool	InvalidateChannels (unsigned int channelType)
	Notify that channels that have cache should be recomputed (ie, UVW channel or normal channel for example). This give better control than Invalidate(OBJECT_INV_CHANNELS) which invalidate any channel information. We can specify with this method what need to be invalidated depending on the performed operation. Return true, if a cache has been invalidated.

unsigned int	GetInvalidateFlags () const
	Return the flags that have been invalidated.

bool	IsInvalidate (OBJECT_UPDATE_PROPERTIES flag) const
	Allow to know if an invalidate flag has been set. Invalidate flag is reset when Update is called.

longint	GetUpdateStamp (OBJECT_UPDATE_PROPERTIES flags) const
	Allow to know if the given flag changed between two call.

virtual bool	MatrixTransform (const C4x4Matrix &matrix)
	Transform the 3D information with the given matrix. The object should not be instanciated or all instance are modified.

virtual void	InheritFlags (const C3DBaseObject &srcObject, int copyflags=OBJECT_COPY_DEFAULT)
	This methods only inherits srcObject flags and custom data and optionaly objectGUID / instanceID if srcObject is to be replaced by the object. It does not modify the data structure.

	return OBJECT_KINDOF, which defines the kind of object.
