vrjs-trackr-g4

This is an npm module for the vrjs framework that utilizes the [trackr-polhemus-g4] server to connect to a Polhemus G4 tracking system

Installation

npm install vrjs-trackr-g4

Usage

Important In order for this module to run, you must have the trackr-polhemus-g4 tracking server installed and running on your machine. This module does not directly communicate with the tracking system, instead it connects over local TCP to the trackr-polhemus-g4 application server.

In your code, you can create a trackr object with the THREE object:

var factory = require('vrjs-trackr-g4')
var trackr = factory.make(THREE);

You can add objects to sensors using the add method

trackr.add(object, sensor_number);

In your animation loop, simply call the poll method and the module will automatically apply the sensor position and orientation to all tracked objects in the scene.

trackr.poll()

You can apply optional positional offsets to the sensor and customized scalling using the offset and scale methods. See source for details.
