Cull is one of the major IPL sections used in plaintext map placement files. It is used to create zones with different behaviour like mirrors or fixed camera positions just as it is able to influence the environment. For example it is able to disable rain in certain areas.

GTA III / Vice City

Cull zones in the first 2 parts of the GTA 3D series are built by a box which is controlled by various flags.

CenterX, CenterY, CenterZ, LowerLeftX, LowerLeftY, LowerLeftZ, UpperRightX, UpperRightY, UpperRightZ, Flags, Unknown
Identifier Description
CenterX, CenterY, CenterZ
A point which defines the center of the box in real world coordinates
LowerLeftX, LowerLeftY, LowerLeftZ
A point which corresponds to the lower left corner of the box.
UpperRightX, UpperRightY, UpperRightZ
A point which corresponds to the upper right corner of the box.

Flags

Flags are numbers which are build out of a collection of numbers formed by the power of 2-numbers lower than 231. Some are defining various behaviours of the zone. They can be combined by simply adding one lag value to another.
