Data types used commonly by the pre-Paradise Burnout games.
 
= VectorsNumeric =
=== CGtV3d ===
A structure containingcomprised of three floating-point component values (x, y, z), bundled into a vectorsingle ofunsigned type128-bit value <code>RwV3dmData</code>.
 
Often used to represent a point in 3D space.

=== CGtV3dPlus ===
Very similar to the CGtV3d type, but includes an additional "plus" component. This extra component may be used to represent a different, but related quantity e.g. length.

=== CGtRGBA ===
A structure used to represent an RGBA color. It is an alias of the type <code>CGtV4d</code>.
 
= Hashes =
=== CGtHash ===
<code>CGtHash</code> is aA derivative of CRC-32—a32 — a 32-bit value storing the hash of a given string, generated via a custom hash function. These hashes are used by the Takedown-era games to identify and properly assign values within files such as the [[Value Database]].
 
=== GtID ===
<code>GtID</code> is aA data type used in many Criterion games as an identifier for objects. It is an alias of the type <code>uint64_t</code> and is used to store a compressed ASCII string.
 
For example, the string <code>BURNOUT</code> would be represented by the GtID <code>6226094955724800000</code>.
