[osg-users] Create animation of growing line between points

[Drake Aldwyn]

Hi, ladies and gentlemen
I humbly ask you for help :3. 
For example, i have few points  and i want to create animation of line that grows from one of the point to all another, like branching tree but cant find  so far any information about how to achieve this. Any help will be very appreciated because i don't know where and in what direction i should start to research. 
... 

Thank you!

Cheers,
Drake
