CAR Format (Carnivores)

CAR Format (Carnivores)

Format type	3D Model
Model type	Polygon
Maximum number of polygons	400
Maximum number of vertices	938
Games	Carnivores

The CAR Format (Carnivores) is used by Carnivores, Carnivores 2, and Carnivores Ice Age as 3D model files for the animals and hunter, weapons, dropship, and wind indicator, and are located in the \HUNTDAT folder (in Carnivores 2 and Ice Age, the weapon CAR files are instead located in \HUNTDAT\WEAPONS). The 3DF Format is a simplified version of this format.

"CAR" may be short for "character"; note that it is not short for Carnivores, since the extension was used for a similar (though presumably slightly simpler) CAR Format (Chasm: The Rift), several years before development on Carnivores would have begun.
