root/OpenSceneGraph/trunk/src/osgPlugins/3ds/tracks.h @ 10076

Revision 10076, 6.7 kB (checked in by robert, 4 years ago)

From Neil Hughes, converted across to use istream for reading data from file to enable reading .3ds files over http (use OSG's libcurl plugin).

From Robert Osfield, ammendments of the above to better support reading of files from local directories.
