Unigine.WorldBoundBox Struct
Notice
The functions listed below are the members of the Unigine.MathLib namespace.
This structure serves to construct the bounding box in double precision coordinates.
Bounding boxes has better precision quality but it takes more time for calculation in comparison with bounding spheres.
By using this structure you can easily find the common bounding box for several objects by expanding the bounding box.
