Sorry for late reply.
Not really. Being able to compute the position will help me accomplish several other stuff, such as finding where the label’s screen location is. With that, I’ll be able to put an icon (billboards… waiting and hoping for the future where Entities can have multiple billboards as said in this post:
next to the label. This is an important feature for us. For instance, here is my entity:
billboard : Toyota-Supra-Vehicle-Icon.gif
label: Toyota Supra
icon to the left of the label : Toyota-Logo.png
icon to the right of the label: Japanese-flag.png
So this entity will show not only the vehicle and its name, but it’s brand name and what country it was made in (this is just an example). This would be another reason why i’d need to compute the position.
