Member Function Documentation

◆ add_is900_analog()

int vrpn_Tracker_InterSense::add_is900_analog ( const char *  analog_device_name,
int  sensor,
double  c0Min = -1,
double  c0Low = 0,
double  c0Hi = 0,
double  c0Max = 1,
double  c1Min = -1,
double  c1Low = 0,
double  c1Hi = 0,
double  c1Max = 1 
)

Add the analog part of an IS900 joystick device to one of the sensors This allows configuration of an InterSense IS-900 The optional parameters specify the clipping and scaling to take the reports from the two joystick axes into the range [-1..1]. The default is unscaled.

This function indicates to the driver that there is an InterSense IS-900- compatible joystick device attached to the port (a Wand).

The driver will configure the device to send reports indicating the current status of the analogs when they change. Note that a separate call to add_is900_button must be made in order to enable the buttons on the wand: this routine only handles the analog channels.

The c0 and c1 parameters specify the clipping and scaling to take the reports from the two joystick axes into the range [-1..1]. The default is unscaled.

This routine returns 0 on success and -1 on failure (due to the sensor number being too large or errors writing to the device or can't create the analog).

◆ add_is900_button()

int vrpn_Tracker_InterSense::add_is900_button ( const char *  button_device_name,
int  sensor,
int  numbuttons = 5 
)

Add an IS900 button device to one of the sensors This allows configuration of an InterSense IS-900.

This function indicates to the driver that there is some sort of InterSense IS-900- compatible button device attached to the port (either a Wand or a Stylus).

The driver will configure the device to send reports when buttons are pressed and released.

This routine returns 0 on success and -1 on failure (due to the sensor number being too large or errors writing to the device or can't create the button).

◆ set_sensor_output_format()

int vrpn_Tracker_InterSense::set_sensor_output_format ( int  station)
protected

Augments the basic Fastrak format to include IS900 features if needed.

This routine augments the basic sensor-output setting function of the Intersense to allow the possibility of requesting timestamp, button data, and/or analog data from the device.

It sets the device for position + quaternion + any of the extended fields.

Returns 0 on success and -1 on failure.
