-------------------------------------------------------------------------------- L I T T L E B I G A D V E N T U R E 1 3D Models Format - used for LBA 3D Object Viewer Revision 1 Author: Alexandre Fontoura [alexfont] Email: [email protected] Last Modification: 31.08.2006 [#] [ INFORMATION ] ------------------------------------------------------------ This document describes the format in which the LBA1Relentless 3D models are stored in. I used this information in the generation of my LBA 3D Object Viewer. If you find any errors in this document please email me the details, also if you find new stuff please notify me. This information is provided AS IS. [#] [ 3D BASICS ] -------------------------------------------------------------- Here's some 3D little notions this document will talk about. - Points: is an entity with a location in space. - Elements: is a group of various points. - Shades: is the blocking of sunlight by any object, and also the shadow created by that object. - Polygons: is a closed planar path composed of a finite number of sequential line segments. - Vertexs: is a corner of a polygon (where two sides meet). [#] [ FORMAT ] ----------------------------------------------------------------- u16 = unsigned short (16bit) u32 = unsigned int (32bit) byte (8bit) + = to add in the previeous script bytes -------------------------------------------------------------------------------- [ Header ] 00: u16 Body Flag (bitmask) 02: u16 aabb mins x 04: u16 aabb maxs x 06: u16 aabb mins y 08: u16 aabb maxs y 0A: u16 aabb mins z 0C: u16 aabb maxs z 0E: u16 Dummy Offset (to jump to offset 1A) 10..18: - Unused [ / Header ] BodyFlag: 16 bits - the 2nd bit (Little endian) marks the model as animated model [ Points ] 1A: u16 Number of points in the body |> Do this "Number of points in the body" times.
