In WoW 2.0+ Blizzard are now storing rotation data in 16bit values instead of 32bit. I don't really understand why as its only a very minor saving in model sizes and adds extra overhead in processing the models. Need this structure to read the data into.
struct PACK_QUATERNION {
__int16 x,y,z,w;
};
class Quat16ToQuat32 {
public:
static const Quaternion conv(const PACK_QUATERNION t)
{
return Quaternion(
float(t.x < 0? t.x + 32768 : t.x - 32767)/ 32767.0f,
float(t.y < 0? t.y + 32768 : t.y - 32767)/ 32767.0f,
float(t.z < 0? t.z + 32768 : t.z - 32767)/ 32767.0f,
float(t.w < 0? t.w + 32768 : t.w - 32767)/ 32767.0f);
}
};
