NAME

SbVec2ub -

SYNOPSIS

#include <Inventor/SbVec2ub.h>

Detailed Description

The SbVec2ub class is a 2 dimensional vector with unsigned 8-bit integer coordinates.

This vector provides storage for a vector in 2 dimensions as well as simple integer arithmetic operations.

Constructor & Destructor Documentation

SbVec2ub::SbVec2ub (void) [inline]

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

SbVec2ub::SbVec2ub (const uint8_t v[2]) [inline]

Constructs an SbVec2ub instance with initial values from v.

SbVec2ub::SbVec2ub (uint8_t x, uint8_t y) [inline]

Constructs an SbVec2ub instance with the initial vector endpoint set to <x,y>.

SbVec2ub::SbVec2ub (const SbVec2b & v) [inline, explicit]

Constructs an SbVec2ub instance with initial values from the 8-bit vector v.

SbVec2ub::SbVec2ub (const SbVec2us & v) [inline, explicit]

Constructs an SbVec2ub instance with initial values from the unsigned short integer precision vector v.

SbVec2ub::SbVec2ub (const SbVec2ui32 & v) [inline, explicit]

Constructs an SbVec2ub instance with initial values from the unsigned 32-bit integer precision vector v.
