What's in a corpse? | |||
*A space for notes (160 bytes) : often the name of the file the corpse was taken when packing the array. | |||
*A link to the [[OBD:ONCC|ONCC]] (model that should be used for the corpse) : that's 4 bytes as usual. | |||
*Then, 19 bones, each of them defined by absolute orientation and position (unlike in a TRAM, where orientations are relative)<br>Every bone is (3x3 + 3)x4 = 48 bytes, so that's 19x48 = 912 bytes. | |||
*Finally, an axis-aligned bounding box (2x3x4 = 24 bytes) | |||
The total size of a corpse is thus : | |||
;What's in a bone?:The absolute orientation is defined in a "heavy" way ''via'' an orthonormal trihedron : | |||
:three 3D vectors '''x''', '''y''' and '''z''', each of length 1, at right angles with each other, and ordered "directly" | |||
:(like Oni's world axes : if '''x''' points left and '''y''' points up then '''z''' points to ''front'', not back). | |||
:Each one of those vectors is stored as 3 floats (3x4 bytes), first '''x''', then '''y''', then '''z''' (so 3x3x4 = 36 bytes in total). | |||
:The absolute position '''R''' is stored as 3 floats right after the orientation trihedron. That's another 12 bytes, so 48 bytes in total. | |||
:''Reminder : the 2nd coordinate of'' '''R''' ''aka'' y ''is the height of the bone (of its parent node)'' | |||
;Example:first corpse of '''00565-.CRSA''' in '''level3_Final.dat'''. | |||
:Offsets are measured from the start of the corpse chunk. | |||
