Summary

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.
Returns an empty list ([]) if object is not found.

Caveats

  • The reported box for objects and avatars is too small by 0.1 meter in all three dimensions, missing the physics tolerance buffer. This error is retained for backward script compatibility. Subtract <0.05, 0.05, 0.05> from min_corner and add <0.05, 0.05, 0.05> to max_corner for a corrected box.
  • 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.

   touch_start(integer total_number)

       list box = llGetBoundingBox(target);
       vector center = (llList2Vector(box, 0) + llList2Vector(box, 1)) * 0.5;
       vector size = llList2Vector(box, 1) - llList2Vector(box, 0);
       llSetPrimitiveParams([PRIM_POSITION, center, PRIM_SIZE, size]);
       llSetText("Name: " + llDetectedName(0) + ", UUID: " + (string)target + 
               "\nBounding Box Size: " + (string)size, <1.0, 1.0, 1.0>, 1.0);
