Detailed Description

The SbVec4us class is a 4 dimensional vector with unsigned short integer coordinates.

This vector class provides storage for a 3 dimensional homogeneoues vector (with the 4 components usually referred to as <x, y, z, w>) aswell as simple integer precision arithmetic operations.

Constructor & Destructor Documentation

SbVec4us::SbVec4us (void) [inline]The default constructor does nothing. The vector coordinates will be uninitialized until a call the setValue().

SbVec4us::SbVec4us (const unsigned short v[4]) [inline]Constructs an SbVec4us instance with initial values from v.

SbVec4us::SbVec4us (unsigned short x, unsigned short y, unsigned short z, unsigned short w) [inline]Constructs an SbVec4us instance with the initial homogeneous vector set to <x,y,z,w>.

SbVec4us::SbVec4us (const SbVec4s & v) [inline, explicit]Constructs an SbVec4us instance with initial values from the unsigned short integer precision vector v.

SbVec4us::SbVec4us (const SbVec4ub & v) [inline, explicit]Constructs an SbVec4us instance with initial values from the 8-bit integer precision vector v.

SbVec4us::SbVec4us (const SbVec4ui32 & v) [inline, explicit]Constructs an SbVec4us instance with initial values from the unsigned 32-bit integer precision vector v.
