Polhemus for C++

Introduction

This package is a development library for C++ to use Polhemus Fastrak or Isotrak2 on IRIX and WIN32 platforms. Please chceck the download site on SourceForge.net to get the package and the samples.

Setup

To use the package, you have to make a library from following four source files at first.

polhemus.h, polhemus.cpp, serial.h, serial.cpp

Use the following compiler flags to create the library.

COMPILER FLAG	PURPOSE
WIN32	Support for Windows9x//NT platform.
SGI	Support for IRIX.
ISOTRAK2	Support for ISOTRAK2. If you don’t use the flag, the library supports Fastrak.

Class Overview

Polhemus Class

class CPolhemus : public CSerial
{
public:
  CPolhemus(char *device, int speed);
  ~CPolhemus();
  int GetActiveReceiverN(void)
  void GetPosition(int nReciver, Point3d p3Pos);
  void GetOrientation(int nReciver, Euler eOri);
};

CPolhemus(char *device, int speed)

• device : Specifies a string of the serial port. You can use the platform independent defines SERIAL1 or SERIAL2 that are defined in “serial.h”
• speed : Specifies the baud rate that is a communication speed with a Polhemuse device.

The constructor creates an instance that is used to communicate with a Polhemus device.

int GetActiveReceiverN(void)

The method returns a number of active receivers.

void GetPosition(int nReceiver, Point3d p3Pos)

The method retrieves a current position of a specified active receiver. Point3d is typedefed as an array of 3 floats. The valid range of the nReciver is from 1 to the value returned by GetActiveReciverN().

void GetOrientation(int nReceiver, Euler eOri)

The method retrieves current euler angles of a specified active receiver. Euler is typedefed as an array of 3 floats. The valid range of the nReciver is from 1 to the value returned by GetActiveReciverN().
