Changeset 3127 in orxonox.OLD for orxonox/branches/images/importer

Message:

orxonox/branches/images: Implemented a Way to read in the Files from any Directory.

1. New Class created: PathList, handles lists of Paths (patrick… i really think this list is so small, that it does not make sense to use the list.h instead)
2. Implemented it so it works. (windows-users should now be able to drag a file onto the importer, and it displays the file with all the maps and textures on it, if they are in the same directory as the obj-file)

Location:

orxonox/branches/images/importer

Files:

• framework.cc (modified) (2 diffs)
• material.cc (modified) (10 diffs)
• material.h (modified) (4 diffs)
• object.cc (modified) (1 diff)
