Data types used commonly by the pre-Paradise Burnout games.

Vectors[edit | edit source]

CGtV3d[edit | edit source]

A structure containing a vector of type RwV3d.

Offset Length Type Name Description Comments
0x0 0x10 u_long128 mData 16 bytes holding an RwV3d object

CGtV3dPlus[edit | edit source]

Hmmm...
To do:
Find out what object this holds.

Matrices[edit | edit source]

CGtAxisAlignedBox[edit | edit source]

Offset Length Type Name Description Comments
0x0 0x10 CGtV3d mSup Supremum vertex
0x10 0x10 CGtV3d mInf Infimum vertex

CGtLine[edit | edit source]

A structure comprised of two vectors, used to represent a line in 3D space.

Offset Length Type Name Description Comments
0x0 0x10 CGtV3d mEndPoint Start point
0x10 0x10 CGtV3d mEndPoint End point

CGtMatrix3x4[edit | edit source]

A structure comprised of four vectors.

Offset Length Type Name Description Comments
0x0 0x10 CGtV3d mRight Right
0x10 0x10 CGtV3d mUp Up
0x20 0x10 CGtV3d mAt At
0x30 0x10 CGtV3d mPos Position

CGtRGB[edit | edit source]

A vector with three floats, each representing a primary additive of an RGB color.

Name Type Length Comments
CGtRGB CGtV3d 0x10 Red, green, and blue additives, respectively

Hashes[edit | edit source]

CGtHash[edit | edit source]

CGtHash is a derivative of CRC-32—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[edit | edit source]

GtID is a data type used in many Criterion games as an identifier for objects. It is an alias of the type uint64_t and is used to store a compressed ASCII string.

For example, the string BURNOUT would be represented by the GtID 6226094955724800000.

Name Type Length Comments
GtID RwUInt64 0x8

RenderWare data types[edit | edit source]

Hmmm...
To do:
Move this section to its own page eventually, as these types originate from the RenderWare engine itself as opposed to any external codebases.

RwV3d[edit | edit source]

A structure comprised of three floats, mainly used to represent the location of a point in 3D space.

Offset Length Type Name Description Comments
0x0 0x4 RwReal x X value
0x4 0x4 RwReal y Y value
0x8 0x4 RwReal z Z value

RwBBox[edit | edit source]

A structure defining the supremum and infimum vertices of a bounding box.

Offset Length Type Name Description Comments
0x0 0xC RwV3d sup Supremum vertex
0xC 0xC RwV3d inf Infimum vertex

RwPlane[edit | edit source]

Offset Length Type Name Description Comments
0x0 0xC RwV3d normal
0xC 0x4 RwReal distance

RwRGBA[edit | edit source]

Offset Length Type Name Description Comments
0x0 0x1 RwUInt8 red
0x1 0x1 RwUInt8 green
0x2 0x1 RwUInt8 blue
