I am browsing through the Second Life viewer code to figure out how the
client does velocity interpolation to find out the position information
of the avatars in the camera vicinity. From what I have learnt, update
packets are sent by the server only when there's a change in the
avatar's velocity, acceleration, etc. Viewer uses velocity
interpolation to find out the missing values in-between the update
packets, and moves the avatars and objects accordingly.
So if
anybody has any information on what the client does here and how it
does it, please pass it. It would be very much appreciated. Even if you
know of any other place where this information is contained/discussed,
please pass along.
