SUR File Format
Compiled By Lancer Solurus with Adoxa's help
All values in HEX unless otherwise noted (Size in decimal)
*****************************************
Size(d) Type Comment
** Header
4 string 'vers' - Version
4 float 2.0
** Section header
4 ULONG CRC
4 ULONG Surface Type Count (!fxd, exts, surf & hpid)
4 string '!fxd' - Part header
4 string 'exts' - Tag
12 XYZ Box minimum
12 XYZ Box maximum
** Surface tag
4 string 'surf' - Surface
** Surface header 0x00000034
4 ULONG Surface offset, bytes to next HPID or section (this addr + offset)
** Surface base pointer 0x00000038
12 XYZ Center
12 XYZ Inertial damping
4 float Radius for visibility (set this large enough to surround entire object to keep it from 'popping', 1.5*radius is good)
1 byte Scaler 0 - 250
3 byte Duplicate of surface offset above
4 ULONG Bits section offset (surface header start addr + offset)
4 ULONG 0 unused
4 ULONG 0 unused
4 ULONG 0 unused
** Face list header (size = 16*face lists)
4 ULONG Vertex list offset (this addr + offset)
4 ULONG Cmpnd/HP CRC or bits offset if 'last face group flag' is set
1 byte Type 4-normal face, 5-face linkage (final face list entry)
3 byte Referenced vertex count, unused by FL, simply set to 0
4 ULONG Face count
** Face list (size = 16*Face count)
12 bits Face number nn xn xx xx (4 bytes) max 16,384 faces
12 bits Opposite face xx nx nn xx
1 byte Flag xx xx xx nn
2 WORD Vertex index 1 nn nn xx xx
15 bits Opposite offset xx xx nn nn (bits 0-14)
1 bit Last Face Group Flag xx xx xx nx (bit 15) (only set if more than 1 face group)
2 WORD Vertex index 2
15 bits Opposite offset
1 bit Last Face Group Flag
2 WORD Vertex index 3
15 bits Opposite offset
1 bit Last Face Group Flag
** Vertex list (size = 16*Vertex count)
12 XYZ Vertex position
4 ULONG Cmpnd/HP CRC
** Bits section (as in 24 bit bitmap)
4 ULONG Sibling offset {Bits base addr + offset)
4 ULONG Triangle offset (this bits base addr - face base offset (0-fbo)) (if sibling offset is not 0, this is 0)
12 XYZ Center
4 float Radius
4 ULONG Scaler 0 - 250 (XX YY ZZ xx) - xx is always 00 since it's unused
