Detailed DescriptionThe SbBox3f class is an abstraction for an axis aligned 3 dimensional box​. This box abstraction class is used by other entities in the Coin library for data exchange and storage​. It provides a representation of the defining corners of a box in 3D space, with the sides aligned with the 3 principal axes​. See also SbBox2d, SbBox2f, SbBox2i32, SbBox2s, SbBox3d, SbBox3i32, SbBox3s, SbXfBox3d, SbXfBox3f
