The SbVec2b class is a 2 dimensional vector with 8-bit integer coordinates.
This vector provides storage for a vector in 2 dimensions as well as simple integer arithmetic operations.
|
inline |
The default constructor does nothing. The vector coordinates will be uninitialized until you do a setValue().
|
