NAME
SbVec2b
SYNOPSIS
#include <Inventor/SbVec2b.h>
Detailed Description
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.

Constructor & Destructor Documentation
- SbVec2b::SbVec2b (void) [inline]
- The default constructor does nothing. The vector coordinates will be
uninitialized until you do a setValue(). - SbVec2b::SbVec2b (const int8_t v[2]) [inline]
- Constructs an SbVec2b instance with initial values from v.
- SbVec2b::SbVec2b (int8_t x, int8_t y) [inline]
- Constructs an SbVec2b instance with the initial vector endpoint set to <x,y>.
- SbVec2b::SbVec2b (const SbVec2ub & v) [inline, explicit]
- Constructs an SbVec2b instance with initial values from the unsigned 8-bit vector v.
- SbVec2b::SbVec2b (const SbVec2s & v) [inline, explicit]
- Constructs an SbVec2b instance with initial values from the short integer precision vector v.
- SbVec2b::SbVec2b (const SbVec2i32 & v) [inline, explicit]
- Constructs an SbVec2b instance with initial values from the 32-bit integer precision vector v.
Member Function Documentation
- SbVec2b & SbVec2b::setValue (const int8_t v[2]) [inline]

getValue()
- SbVec2b & SbVec2b::setValue (const SbVec2ub & v)
- Sets this vector to the unsigned 8-bit integer precision vector v,
converting the vector to an 8-bit integer precision vector - SbVec2b & SbVec2b::setValue (const SbVec2s & v)
- Sets this vector to the short integer precision vector v, converting the vector to an 8-bit integer precision vector.
