[osg-users] Road/Line label suggest

2008-01-13 Thread ZHMW 
Hi EveryOne!

I want suggests about the text label of the road or line vector. I
want the label display along the line. And when I rotate the camera, the
label should face to the screen and also along the line. How can i do
that?Hope your suggest.

   Thanks.

Hi Dvaid,

The is no support in osgText for orientating around a user defined
axis so you'll either have to place the Text under an osg::Billboard
or write your own custom Transform node to produce the appropriate
transform.

I'd suggest you take a look at the osgtext example. Also, look at the
AutoTransform class and look at places where it's used in the examples.
