Furthermore, the fileformat itself is not yet big-/little-endian independent and may contain fields that are either ignored or misinterpreted by the library. ******************************************************************************** ******************************************************************************** ******************************************************************************** o------------------------------------------------------------------------------o | 2 cal3d skeleton file (.csf) - read by Cocos3D | o------------------------------------------------------------------------------o Stored in this file is the hierarchy of bones that composes the skeleton. description length type comments ------------------------- ------ -------- ----------------------------------- [header] magic token 4 const "CSF\0" file version 4 integer 1300 number of bones 4 integer ambient light red 4 float scene ambient light color red (version 1300 and above) ambient light green 4 float scene ambient light color green (version 1300 and above) ambient light blue 4 float scene ambient light color blue (version 1300 and above) [first bone] length of bone name 4 integer bone name var string translation x 4 float relative translation to parent bone translation y 4 float translation z 4 float rotation x 4 float relative rotation to parent bone rotation y 4 float stored as a quaternion rotation z 4 float rotation w 4 float local translation x 4 float translation to bring a vertex from local translation y 4 float model space into bone space local translation z 4 float local rotation x 4 float rotation to bring a vertex from local rotation y 4 float model space into bone space local rotation z 4 float local rotation w 4 float parent bone id 4 integer index to parent bone lighting type 4 integer lighting type (version 1300 and above) bone color red 4 float bone color red (version 1300 and above) bone color green 4 float bone color green (version 1300 and above) bone color blue 4 float bone color blue (version 1300 and above) number of children 4 integer [first child] child bone id 4 integer index to child bone [all other children] ...
