Hi,

I'm trying to find the boundary box of an object. To do this im using BaseObject::GetRad()
That's works fine if the object isn't rotated.

If for example I rotated a default cube by 45 degrees on the Pitch axis, the boundary box would be slightly larger than Vector(50,50,50)(which GetRad() returns).

Will I have to calculate it myself?

Thanks

To avoid to calculate yourself the bounding box, you could try something like this:

    
    
    
    
    // PSEUDOCODE
    
    
    
    
    1. Make a copy of the object global matrix (oldMtx = obj->GetMg())
    
    
    
    
    2. Assign an identity global matrix to the object (obj->SetMg(identity))
    
    
    
    
    3. Calculate the object bounding box (obj->GetRad())
    
    
    
    
    4. Reassign the original global matrix to the object (obj->SetMg(oldMtx))

Hope it helps...
