Region crossings

This section is incomplete

• Every OpenSimulator frame (approximately every 89ms), every avatar is checked to see whether it has crossed into a neighbouring region (currently in ScenePresence.CheckForBorderCrossing().
  • This check is done by extrapolating the avatar's position in the next 100ms at its current heading and velocity
• If the extrapolation shows the avatar moving into a new region, then IEntityTransferModule.Cross() is triggered to initiate the cross process.
