The body holds "flavors" and there is no special order for the ocurrence of flavors in a 3DO file. Just one thing is needed: any flavor called must have an offset minor to the caller flavor's offset.
There are two types of Flavor #0, one for regular polygons, and one for texture-mapped polygons. The texture-mapped polygons also have an x and y extra coordinates defined for the location within the MIP image that this vertex corresponds to.
Each flavor allows the sim to define a particular property of the 3D object, a track 3DO file will need certain flavors, meanwhile trackside objects andcars will need other.
The units used by the sim are:
Coordinates: 1 unit = (1/500) inches
Angles : 2147483648 units = 180 degrees
Units related to track length or position are defined by the TRK file.
All numeric values are stored as long integers, except the X and Y MIP coordinates from the Flavor #0.
Offsets are calculated from the end of the header, and start in zero.
If a flavor doesn't need to call an offset, but its structure requires
a call, the value will be set to zero.
