SbVec4ub

NAME

SbVec4ub -

SYNOPSIS

#include <Inventor/SbVec4ub.h>

Detailed Description

The SbVec4ub class is a 4 dimensional vector with unsigned 8-bit 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

SbVec4ub::SbVec4ub (void) [inline]

The default constructor does nothing. The vector coordinates will be uninitialized until a call the setValue().

SbVec4ub::SbVec4ub (const uint8_t v[4]) [inline]

Constructs an SbVec4ub instance with initial values from v.

SbVec4ub::SbVec4ub (uint8_t x, uint8_t y, uint8_t z, uint8_t w) [inline]

Constructs an SbVec4ub instance with the initial homogeneous vector set to <x,y,z,w>.

SbVec4ub::SbVec4ub (const SbVec4b & v) [inline, explicit]

Constructs an SbVec4ub instance with initial values from the 8-bit integer precision vector v.

SbVec4ub::SbVec4ub (const SbVec4us & v) [inline, explicit]

Constructs an SbVec4ub instance with initial values from the unsigned short integer precision vector v.

SbVec4ub::SbVec4ub (const SbVec4ui32 & v) [inline, explicit]

Constructs an SbVec4ub instance with initial values from the unsigned 32-bit integer precision vector v.
