This is the first coding bounty posted, relatively low dollar amount
since it's less work compared to some of the other outstanding
questions. We need to figure out the camera fields in the AgentUpdate
packet. Are they based on relative position in the sim? What is the
correlation between each of the vectors? What are good default values
if you assume a first person camera and an avatar standing in a sim at
128.0, 128.0, 25.0? Here's the packet:
High 00005 - AgentUpdate - Untrusted - Unencoded
1297 AgentData (01)
0030 ID (LLUUID / 1)
0116 ControlFlags (U32 / 1)
0131 CameraAtAxis (LLVector3 / 1)
0206 Far (F32 / 1)
0252 CameraCenter (LLVector3 / 1)
0253 CameraLeftAxis (LLVector3 / 1)
0350 HeadRotation (LLQuaternion / 1)
0607 CameraUpAxis (LLVector3 / 1)
0961 BodyRotation (LLQuaternion / 1)
1189 Flags (U8 / 1)
1255 State (U8 / 1)
So far we've determined that Far is the viewing distance, and that
it's probably safe to use all zeroes for the quaternions (the
rotations). Bonus if you figure out the Flags and State field (and why
they always seem to be 221). Let me know if you need a compiled
version of snowcrash for packet dumps, or any libsecondlife code
written to assist in solving the mystery. Payout is through PayPal only.

This was just solved, all except for the CameraLeftAxis and CameraUpAxis
(and the Flags and State fields). The bounty is being removed since the
code now does what we want, which is receive ObjectUpdate packets from
the location the avatar is standing at. Any further information would
still be helpful though.
