Changeset 8775 in orxonox.OLD for branches/terrain/src/lib/graphics/importer/terrain/frustum.h

Timestamp:

Message:

• Applied a small change to sounrd_buffer and ogg_player in order to load the buffers correctly on big endian systems.
• Did a lot of cleanup for the terrain rendering system. Added destructors and constructors.
• The cameras clip-space has to be set to a very large range to display the skybox. The maximum clip distance for the terrain needs to be smaller.
