Hello!
PagedLOD seems to be very interesting! I tried to load a database whose the
extension is .osg, and the database is displayed. But the points stocked into
the database are displayed just like pixels. And yet, the points are
pointsprites and they are not displayed as pointsprites. I have noticed that in
the .osg file there is not the link to the picture file (.jpg) for the
texture... What is the solution to tell the .osg file to use my picture to have
pointsprites as i want?
I thank you!
Bye
