This is the beginnings of a gem to control Microsoft's word wide telescope from Ruby. It currently focuses on the desktop client
Control of pointing of telescope. Earthquake like notifications
Connecting to a WWT instance is as simple as WWT.new. This defaults to connecting to http://0.0.0.0:5050.
You can also pass in a url and port if needed with WWT.new url, port
Once connected you will get back an instance of WWTClient which allows you to pass commands off to WWT.
You can select the current mode by WWTClient.look_at thing where thing can be "Earth", "Sky", "SolarSystem" etc
You can make the telescope move incrementally (the equivalent of pressing keys in the GUI interface) using WWTClient.move motion where motion can be ["Left", "Right", "Up", "Down", "Clockwise", "CounterClockwise",]
We support the creation of layers within the WWT framework using layer=WWTClient.new_layer :frame=>frame, :name=>name, :data=>['ra','dec','time'] where frame is the frame this layer is sent to and name is a name given to a layer and data tells us what type of data this layer is going to show. This returns an instance of WWT_layer which allows access to that layer. There are many other options that can be passed in through the hash for a full list look at http://www.worldwidetelescope.org/Docs/WorldWideTelescope_lcapi.html.
We can push data to the layer for visulisation with layer.update :data=>["10","10",'02/03/1999 10:20:33]
Any property of a layer can be got by later.property_with_underscores, for example in the WWT documentation (http://www.worldwidetelescope.org/Docs/WorldWideTelescope_lcapi.html#Table_of_Properties) we have "EndTime" to get this we would call layer.end_time and to set it layer.end_time=
You will need to have an install of WWT on your machine or another machine with port 5050 open. This is where WWT listens to. You also need to have the IP of controlling machine enabled in the list of approved sources in WWT.
gem install WWT
