Member Function Documentation

void openvrml::pointing_device_sensor_node::activate	(	double	timestamp,
		bool	over,
		bool	active,
		const double(&)	point[3]
	)

Convey a pointing device state change.

This function delegates to do_activate.

Parameters:

[in]	timestamp	the current time.
[in]	over	whether the pointing device is over the geometry affected by the pointing device sensor.
[in]	active	whether the pointing device is “active”; e.g., whether a mouse button is currently depressed.
[in]	point	the position of the pointer on the affected geometry.

void openvrml::pointing_device_sensor_node::do_activate	(	double	timestamp,
		bool	over,
		bool	active,
		const double(&)	point[3]
	)		[private, pure virtual]

Called to convey a pointing device state change.

Parameters:

[in]	timestamp	the current time.
[in]	over	whether the pointing device is over the geometry affected by the pointing device sensor.
[in]	active	whether the pointing device is “active”; e.g., whether a mouse button is currently depressed.
[in]	point	the position of the pointer on the affected geometry.
