NAME
SbVec2s -SYNOPSIS
#include <Inventor/SbLinear.h>
Detailed Description
The SbVec2s class is a 2 dimensional vector with short integer coordinates.
This vector class is used by many other classes in Coin. It provides storage for a vector in 2 dimensions as well as simple integer arithmetic operations.

SbVec2s::SbVec2s (const short v[2])
Constructs an SbVec2s instance with initial values from v.
SbVec2s::SbVec2s (const short x, const short y)
Constructs an SbVec2s instance with the initial vector endpoints from x and y.
SbVec2s::SbVec2s (const SbVec2us & v) [inline, explicit]
Sets this vector to the unsigned short integer precision vector v, converting the vector to an short integer precision vector.
Since:
- Coin-2.5
SbVec2s::SbVec2s (const SbVec2b & v) [inline, explicit]
Sets this vector to the 8-bit integer precision vector v, converting the vector to an short integer precision vector.
Since:
- Coin-2.5
SbVec2s::SbVec2s (const SbVec2i32 & v) [inline, explicit]
Sets this vector to the unsigned integer precision vector v, converting the vector to an short integer precision vector.
Since:
- Coin-2.5
SbVec2s::SbVec2s (const SbVec2f & v) [inline, explicit]
Sets this vector to the floating point precision vector v, converting the vector to an short integer precision vector.
Since:
- Coin-2.5
SbVec2s::SbVec2s (const SbVec2d & v) [inline, explicit]
Sets this vector to the double floating point precision vector v, converting the vector to an short integer precision vector.
Since:
- Coin-2.5
