.SH NAME
SbBox2f \- 
.PP
The \fBSbBox2f\fP class is a 2 dimensional box with floating point corner coordinates\&.
.PP
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\&.
