Function: list llGetBoundingBox( key object );

Returns a list that is the bounding box of object relative to its root prim.
Format: [ (vector) min_corner, (vector) max_corner ]

• key object Object or agent in the sim.

The bounding box is for the entire link set, not just the requested prim.


  • if object is an avatar, the reported bounding box is too small by 0.1 meter in all three dimensions. This error is retained for backward script compatibility. Subtract <0.05, 0.05, 0.05> from the first value and add <0.05, 0.05, 0.05> to the second for a corrected box.
  • The bounding box of an avatar sitting on an object includes that object.
  • For server 1.36 and up, the bounding box for an attachment is the avatar's bounding box with the 0.1 meter addition already applied.
    • Attachment bounding boxes do not include any object the avatar is sitting on.
