Changeset 8715 in orxonox.OLD for branches/terrain/src/lib/graphics/importer/md2/md2Model.cc

Timestamp:

Message:

• Added special checks for macosx to acinclude.m4 and configure.ac. This sucks
• Reapplied the endianness checks to the md2_model file. They got lost during the merge operation.
• Tried to do the collision detection for the ground. But somehow it doesn't work. Perhaps an offset will do.
