virtual InterfaceListType* GetCppInterfaceDescription ( InterfaceListType * addToThisList = 0 )

virtual

Get the details of the Cpp Interface The actual interface is exposed in compiled code.

Parameters

addToThisList If not NULL this list will be added to then returned. If NULL a new list will be created.

Returns: A templated list. The caller must call the corresponding free method to safely free the memory.

Reimplemented from GlsEyePoint.

virtual void GetCppInterfaceDescriptionFree ( InterfaceListType * array )

virtual

Frees the memory allocated by a previous call to GetCppInterfaceDescription

Parameters

array Memory allocated by a previous call to GetCppInterfaceDescription

Reimplemented from GlsEyePoint.

void Initialize ( )

protected

Initializes the movement history with the initial state of the eyepoint.

const std::string& LookAtObject ( ) const

inline

Returns: The name of the object that the eyepoint should be always looking at. Lifetime is guaranteed to coincide with the GlsMovingEye's lifetime or until LookAtObject is changed.

void LookAtObject ( const std::string & name )

Sets the name of the object that the eyepoint should be always looking at.

float MaxSpeed ( ) const

inline

Returns the maximum speed in logical units/second which will be used to achive the transition between eyepoints.

void MaxSpeed ( float speed )

Sets the maximum speed in logical units/second which will be used to achive the transition between eyepoints.

void MoveBack ( )

Moves this eyepoint to the previously set eyepoint. If a move is already in progress, it will be immediately stopped, and this move will start.

void MoveForward ( )

Moves this eyepoint to the eyepoint which was last achieved from a MoveBack(). If a move is already in progress, it will be immediately stopped, and this move will start.

Movement_t Movement ( ) const

inline

Returns the type of movement algorithm to use when moving to another eyepoint.

void Movement ( Movement_t movementType )

Sets the type of movement algorithm to use when moving to another eyepoint.

void MoveRelative	(	const Vector &	moveAmount,
		const Vector &	rotation
	)

Moves the eyepoint in view-relative coordinates by the specified amount, over the specified time. The units are in relative screen coordinates: X and Y are pixels, Z is 0->1. See WindowToLogical() or LogicalToWindow().

float MoveTime	(	float	distance,
		float	desiredTime
	)		const

protected

Returns an adjusted move time based on the maximum speed setting. If the speed of moving over distance in desiredTime is greater than the maximum speed setting, the move time will be lengthened.

Parameters

distance	distance in logical units that will be moved.
desiredTime	time in which we wish to cover the specified distance.

void MoveToEye	(	GlsEyePoint *	eye,
		float	moveTime = `2.0f`
	)

Causes this eye to move from its current state to the state specified by the targetEye. It will take moveTime to get there. If a move is already in progress, it will be immediately stopped, and this move will start.

void MoveToEye	(	Group *	eyeGroup,
		float	moveTime = `2.0f`
	)

Causes the eye to move from its current state to each eyepoint in the specified group ending with the last eye in the group. If a move is already in progress, it will be immediately stopped, and this move will start.

void MoveToEyeAdd	(	GlsEyePoint *	eye,
		float	moveTime = `2.0f`
	)

Causes the specified eye to be added to the end of the list of eyes which should be moved through.

void MoveToEyeAdd	(	Group *	eyeGroup,
		float	moveTime = `2.0f`
	)

Causes the specified eyes to be added to the end of the list of eyes which should be moved through.

void MoveToLocation	(	const Vector &	location,
		float	moveTime = `2.0f`
	)

Causes this eye to move to the specified location in the scene without modifying the view direction or any other eye specific information.

Route_t Route ( ) const

inline

Returns the type of route to use when moving to another eyepoint.

void Route ( Route_t routeType )

Sets the type of route to use when moving to another eyepoint.

float RouteDistance ( std::vector< GlsEyePoint * > & eyes ) const

protected

Calculates the distance over the entire route if moving between all eyepoints in the list.

virtual void SetAvailableAttributes ( unsigned int value )

virtual

Specifies which attributes are available for the object. Currently the available attributes cannot be changed after they have been set. (Only the first call has an effect.)

Parameters

value A bitfield specifying which types of attributes to make available.

See also: AvailableAttributesEnum

Reimplemented from GlsEyePoint.

virtual void SetValue	(	int	spec,
		va_list &	args
	)

virtual

Sets an attribute of this object using variable arguments

Parameters

spec	A GLS_Initializer tag
args	A variable argument list

Reimplemented from GlsEyePoint.

void StartMoving ( const MoveParms_t & moveParms )

protected

Queues the move using the passed in movement parameters and sets up the start time and starting state of the move.

Member Data Documentation

float _bufferAngle

protected

This specifies a buffer area around _upVector and -_upVector which the moving eye will try to avoid. Setting this to non-zero avoids flipping problems when orientation passes through _upVector or -_upVector during moves.

bool _firstSegment

protected

This is true when a move is occurring and the route segment being moved along is the very first one in the queue. This is used during sinusoidal movement to smoothly speed up when starting.

std::string _lookAtObject

protected

Automatically adjust the view direction to point at the specified targetObject. This is inactivated when the string is blank. While this is active, the move methods will not control the view direction. They can still control the position and other eye information.

Vector _lookAtReferenceUpVector

protected

The last up vector provided by the user or the move code. Used by the 'look at' algorithm to orient the eyepoint

float _maxSpeed

protected

This specifies the maximum speed in logical units / second which will be used to achive the transition. If the requested transition cannot occur within the requested move time without exceeding the max speed, the move time will be longer than requested. In other words, this limit has priority over any requested moveTime. A MaxSpeed value of < 0.0 means the speed limit is disabled.

std::queue<MoveParms_t> _moveQ

protected

Contains movement parameters for each move that should be performed. The last one contains the final eyepoint to stop at.

EyeState_t _start

protected

Stores this eyepoint's current state at the start of a move and is used in calculating movement during each execution frame.

Vector _upVector

protected

This specifies the up direction and is used when interpolating movement to keep the view oriented 'correctly'.
