Detailed DescriptionThe SbBox3d 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, SbBox3f, SbBox3i32, SbBox3s, SbXfBox3d, SbXfBox3f

SbBox3d::SbBox3d (double minx, double miny, double minz, double maxx, double maxy, double maxz) [inline]Constructs a box with the given corners​. minx should be less than maxx, miny should be less than maxy and minz should be less than maxz if you want to make a valid box​.
SbBox3d::SbBox3d (const SbVec3d & minval, const SbVec3d & maxval) [inline]Constructs a box with the given corners​. The coordinates of min should be less than the coordinates of max if you want to make a valid box​.
SbBox3d::SbBox3d (const SbBox3f & box) [inline], [explicit]Constructs a box with coordinates from box, converting the coordinates to floating point double precision values Since Coin-2​.5
SbBox3d::SbBox3d (const SbBox3s & box) [inline], [explicit]Constructs a box with coordinates from box, converting the coordinates to floating point double precision values Since Coin-2​.5
SbBox3d::SbBox3d (const SbBox3i32 & box) [inline], [explicit]Constructs a box with coordinates from box, converting the coordinates to floating point double precision values Since Coin-2​.5
