Class Description

The ObjectState is the structure that flows up the geometry pipeline.

It contains a matrix, a material index, some flags for channels, and a pointer to the object in the pipeline. This is what is passed down the pipeline, and ultimately used by the Node to Display, Hittest, render.

Constructor & Destructor Documentation

CoreExport ObjectState ( )

Constructor.

The object pointer is initialized to NULL.

CoreExport ObjectState ( Object * ob )

Constructor.

The object pointer is set to the object passed. The tm pointer is set to NULL and the tm and mtl validity intervals are set to FOREVER.

Parameters

ob	The object to initialize the object pointer to.

CoreExport ObjectState ( const ObjectState & os )

Constructor.

The object state is initialized to the object state passed.

Parameters

os	The object state to initialized to os.

CoreExport ~ObjectState ( )

Destructor.

If the tm exists, it is deleted.

Member Function Documentation

void OSSetFlag ( ulong f )

inline

Call this method to update the object state flags.

Parameters

f	The flags to set. The specified flags are ORed into the current state of the flags.

304 { flags |= f; }

void OSClearFlag ( ulong f )

inline

Call this method to clear the specified object state flags.

Parameters

f	The flags to clear.

308 { flags &= ~f; }

ulong OSTestFlag ( ulong f ) const

inline

Call this method to test the specified flags.

Parameters

f	The flags to test.

CoreExport void SetIdentityTM ( )

Sets the object state tm to the identity transformation matrix.

CoreExport void ApplyTM	(	Matrix3 *	mat,
		Interval	iv
	)

Applies the specified matrix to the object state tm.

The object state tm is multiplied by the specified matrix. The specified interval is intersected with the object state tm validity interval.

Parameters

mat	The matrix to apply.
iv	The interval to intersect with the object state's tm validity interval.

CoreExport void CopyTM ( const ObjectState & fromos )

Copies the object state tm (and its validity interval) from the specified object state's tm.

Parameters

fromos The object state whose tm is to be copied.

CoreExport void CopyMtl ( const ObjectState & fromos )

Copies the object state material (and its validity interval) from the specified object state's material.

Parameters

fromos The object state whose material is to be copied.

CoreExport void Invalidate	(	ChannelMask	channels,
		BOOL	checkLock = `FALSE`
	)

Invalidates the specified channels of the object state's object.

Parameters

channels	The channels of the object to invalidate.
checkLock	If checkLock is TRUE and OBJ_CHANNELS is one of the specified channels, the object the object state points to is not deleted if it is locked; otherwise it is deleted.

CoreExport ChannelMask DeleteObj ( BOOL checkLock = FALSE )

Deletes the object state's object.

Parameters

checkLock If checkLock is TRUE, the object the object state points to is not deleted if it is locked; otherwise it is always deleted.

Operators:

Member Data Documentation

Object* obj

Pointer to the object in the pipeline.

The validity interval of the object can be retrieved using obj->ObjectValidity()
