vrjs-trackr-key v0.0.3

vrjs-trackr-key

This is an npm module for the vrjs framework that implements a standard tracker with keyboard controls. The keyboard tracker has 10 channels/sensors that can be toggled, allowing an application to "track" up to ten different sensors.

Installation

npm install vrjs-trackr-key

Usage

Keypresses control the current position and orientation of the active sensor

x/X - moves the active sensor along the x axis
y/Y - moves the active sensor along the y axis
z/Z - moves the active sensor along the z axis
j/J - rotates the active sensor around x axis
n/N - rotates the active sensor around y axis
h/H - rotates the active sensor around z axis
[0-9] - sets the active sensor

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

var keytrackr = require('vrjs-trackr-key')
var trackr = keytrackr.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.
