[osg-users] sensors and engines

In Open Inventor, there are sensors and engines to detect changes of an object and connect the related motions.
Does OSG have similar stuff? How should these functions be done? 

Thanks in advance.

Hi,

you do not need to specify every file in a directory manually. I usually 
create a single directory for a layer (-t) and place my geotiffs in 
there. You then pass the directory as the parameter to -t.
