Object extent x,y,z (width, depth, height)

I am trying to create a trigger object and have two waypointmarker objects created at the same time in relation to the position and size of the trigger object.
In order to do this I need to get the trigger objects width, depth and height but can only seem to get the scale.
I have looked around and was expecting to find an extent method with the width, depth and height in x,y,z format but there isn't one.
I found a method getObjectBox() and thought this might give me the information for the bounding box and that would of done but it doesn't seem to return anything useful.
I have now run out of ideas, and would think this would be as simple as the getPosition() method but I just can't seem to find the correct method to return this information.
I have tried trigger.dump but can't see anything available that might help further.
Any help is appriciated.
Many thanks.
Pejayuk.

I have found a better way of doing this using object groupings posted http://www.garagegames.com/mg/forums/result.thread.php?qt=56024
This will allow me to create a group of objects and have them all move relative to each other so the size of the bounding box or object isn't needed any more.
Thanks for reading.

While working on the local postion system for the object groupings, I created the following functions incase someone else needs them.
Place them as they are in sceneObject.cc and recompile.

getObjectExtent //Returns the extent of the object from its position. X,Y,Z can be in plus or minus depending on rotation of the object from the position.

getObjectBoxCenter //Returns the center position of the object.

These should work fine, but I havn't stress tested them yet.


ConsoleMethod( SceneObject, getObjectExtent, const char*, 2, 2, "Returns the Extent of the objects bounding box in x, y, z.")
{
   char *returnBuffer = Con::getReturnBuffer(256);
   const Box3F& box = object->getObjBox();
   Point3F center;
   box.getCenter(&center);
   Point3F objPos = object->getPosition();
   //To work out the extent we take the objects Position X,Y,Z away from the objects Center X,Y,Z and times it by 2.
   //With will give us the width, depth and hieght in world coordinates in relavant + or - values.
   dSprintf(returnBuffer,256,"%g %g %g", ((center.x - objPos.x)*2), ((center.y - objPos.y)*2), ((center.z - objPos.z)*2));
   return returnBuffer;
}

ConsoleMethod( SceneObject, getObjectBoxCenter, const char*, 2, 2, "Returns the center of the objects bounding box.")
{
   char *returnBuffer = Con::getReturnBuffer(256);
   const Box3F& box = object->getObjBox();
   Point3F center;
   box.getCenter(&center);

   dSprintf(returnBuffer,256,"%g %g %g", center.x, center.y, center.z);
   return returnBuffer;
}
