Couple of Questions- about droidar HOT 5 CLOSED

1. What do you mean with "put a text description"? do you mean adding a text to 
the virtual world which will fly around near the object or do you mean a text 
that should be displayed when the user clicks on the objects or get close to 
the object or whatever?

2. i also thought about this a while ago but i'm still not sure what the best 
solution is. i think something like a arrow with information about the object 
which is far away might be a solution so that the user can be guided to the 
object. i already implemented a small component which will help you doing this 
and i will add a new blogpost about how to do this in the droidar blog ( 
http://droidar.blogspot.com/ ) soon

3. jep i planned to add a little 2d compass view to droidar for a long time but 
didn't have the time jet. its on the todo list so just check the blog from time 
to time and if you find a free to use android compass view or something like 
this tell me;)

1.  For this example.  We are putting a GeoObj in the world with the arrow 
MeshComponent.  We also want some text to go along with that GeoObj and Arrow.  
So the user can see what each of the arrows describe.  So our example is we 
drop a bunch of arrows in the world based on GeoLocation spots, and we want to 
have the description also be able to be seen as text by the user as they 
walk(move) around the world(virtualworld).

Forgot about #3-
3.  Mixar has a good 2d compass that im sure you could use to get that 
functionality into DroidAR.

you can use the 
http://code.google.com/p/droidar/source/browse/trunk/droidar/DroidAR/src/gl/GLTe
xt.java class to display text to the user. just combine two meshes like this:

Mesh arrow = newArrow
Mesh text = new GLText(...
text.setPostion(new Vec(0,0,10)) to move it above the arrow
arrow.addChild(text)

the alternative to GLText would be to use objectFactory.newTextObject(..)
