详细描述

Laputa VR head-mounted display base class

构造及析构函数说明

vrpn_Laputa()

vrpn_Laputa	(	const char *	name,
		vrpn_Connection *	c = NULL )

参数

name	Name of the device.
c	Optional vrpn_Connection pointer to use as our connection.

~vrpn_Laputa()

virtual ~vrpn_Laputa ( )

virtual

Destructor.

成员函数说明

mainloop()

virtual void mainloop ( )

virtual

Called once through each main loop iteration to handle updates. Remote object mainloop() should call client_mainloop() and then call d_connection->mainloop(). Server object mainloop() should service the device and then call server_mainloop(), but should not normally call d_connection->mainloop().

实现了 vrpn_BaseClass.

on_data_received()

void on_data_received ( std::size_t bytes, vrpn_uint8 * buffer )

protected

Extracts the sensor values from each report and calls the appropriate parser.

parse_message_type_1()

void parse_message_type_1 ( std::size_t bytes, vrpn_uint8 * buffer )

protected

Parse and send reports for type-1 message

类成员变量说明

d_timestamp

struct timeval d_timestamp

protected

Timestamp updated during mainloop()
