" class SbBox2f The SbBox2f class is a 2 dimensional box with floating point corner coordinates. This box class is used by many other classes in Coin for data exchange and storage. It provides two box corners with floating point coordinates, which is among other things useful for representing screen or canvas dimensions in normalized coordinates. " class SbBox2s The SbBox2s class is a 2 dimensional box with short integer coordinates. This box class is used by other classes in Coin for data exchange. It provides storage for two box corners with short integer coordinates, which is among other things useful for representing screen or canvas areas in absolute window coordinates.

" class SbBox3f The 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 storage for two box corners with short integer coordinates, which is among other things useful for representing screen or canvas areas in absolute window coordinates. " class SbClip The SbClip class is a generic polygon clipper class. It is used by first adding all vertices in the polygon, and then clipping against any number of planes. If you need to supply additional information per vertex (e.g. texture coordinates), you should supply a callback in the constructor, and a pointer to your vertex structure in addVertex(). For every new vertex created, the callback is called with the line being clipped, including the pointers to your vertex structures and the position of the new (clipped against some plane) vertex. You should then create a new vertex structure, calculate your data (e.g. a new texture coordinate) and return a pointer to this structure. class SbColor The SbColor class contains the red, green and blue components which make up a color value. This class is used within other classes in Coin. It inherits the SbVec3f class, interpreting the 3 component vector as a vector in the RGB cube where the red, green and blue components corresponds to x, y and z respectively. class SbColor4f The SbColor4f class contains the red, green, blue and alpha components which make up a color value.

They are stored in a manner where identical strings are guaranteed to map to the same memory address (as returned by the SbName::getString() method). class SbOctTree The SbOctTree class defines a generic oct tree for fast geometry searches. Be aware that this class is an extension for Coin, and it is not available in the original SGI Open Inventor v2.1 API. " class SbRotation The SbRotation class represents a rotation in 3D space.

" class SbIntList The SbIntList class is a container for integer list arrays. class SbList< Type > The SbList class is a template container class for lists. SbList is an extension of the Coin library versus the original Open Inventor API. Open Inventor handles most list classes by inheriting the SbPList class, which contains an array of generic void* pointers. By using this template-based class instead, we can share more code and make the list handling code more typesafe. " class SbPList The SbPList class is a container class for void pointers. class SbStringList The SbStringList class is a container for arrays of SbString pointers. Note that upon using the equality and inequality operators, the strings themselves are not compared, only the pointer values.

Note that upon using the equality and inequality operators, the SbVec3f objects themselves are not compared, only the pointer values.## DETAILED DESCRIPTION
