2) Data in .FCE file from end of header = 0x2038
2a) Table of vertices
Offset : Header Size + Vertex table offset
Length : Number of Vertices * Size of Vector
Type : Vector[Number of Vertices]
All coordinates are local. Use values from 'Parts' table (file offset 0x0120)
to make them global.
2b) Table of normals
Offset : Header Size + Normal table offset
Length : Number of Vertices * Size of Vector
Type : Vector[Number of Vertices]
These vectors should be normalized. Each normal in this table corresponds to the
vertex in the vertex table with the same index.
2c) Table of triangles
Offset : Header Size + Triangle table offset
Length : Number of Triangles * Size of Triangle
Type : Triangle[Number of Triangles]
Triangle structure:

0x34 0x04 REAL Vertex #3 texture V-coordinate
-------------------------------------------------------------------------
0x38 - size of Triangle
-------------------------------------------------------------------------
Vertex indices are local. Use values from 'First Vertices' table (file offset 0x0420)
to make them global.
2d) Temporary Storage #1
Offset : Header Size + Reserved #1 offset
Length : Number of Vertices * 32
Type : ????
2e) Temporary Storage #2
Offset : Header Size + Reserved #2 offset
Length : Number of Vertices * 12
Type : ????
2f) Temporary Storage #3
Offset : Header Size + Reserved #3 offset
Length : Number of Vertices * 12
Type : ????
2g) Undamaged vertices
Offset : Header Size + Reserved #4 offset
Length : Number of Vertices * 12
Type : Vector
2h) Undamaged normals
Offset : Header Size + Reserved #5 offset
Length : Number of Vertices * 12
Type : Vector
2i) Damaged vertices
Offset : Header Size + Reserved #6 offset
Length : Number of Vertices * 12
Type : Vector
2j) Damaged normals
Offset : Header Size + Reserved #7 offset
Length : Number of Vertices * 12
Type : Vector
2k) Unknown area #1
Offset : Header Size + Reserved #8 offset
Length : Number of Vertices * 4
Type : ????
2l) Driver movements
Offset : Header Size + Reserved #9 offset
Length : Number of Vertices * 4
Type : 4 bytes in length
2m) Unknown area #2
Offset : Header Size + Reserved #10 offset
Length : Number of Vertices * 4
Type : ????
2n) Unknown area #3
Offset : Header Size + Reserved #11 offset
Length : Number of Triangles * 12
Type : ????
All areas should exist. The Driver Movements keeps a value for each vertice.
This value is only used in the part ":OD". If the value for a vertex here is
00 00 00 00, the vertice will rotate when the driver turns the wheel. If it is
04 00 00 00, the vertice won't rotate.
3) Coordinate system. From the car:
X axis points to the right;
Y axis points upward;
Z axis points forward.
4) Notes
LONGINT : long integer (32-bit)
SHORTINT: short integer (8-bit)
REAL : floating point number (32-bit)
