SbVec4us

NAME

SbVec4us -

SYNOPSIS

#include <Inventor/SbVec4us.h>

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.

Member Function Documentation

SbVec4us & SbVec4us::setValue (const unsigned short v[4]) [inline]

Set new coordinates for the vector from v. Returns reference to self.

See also:

getValue()

SbVec4us & SbVec4us::setValue (unsigned short x, unsigned short y, unsigned short z, unsigned short w) [inline]

Set new coordinates for the vector. Returns reference to self.

See also:

getValue()

SbVec4us & SbVec4us::setValue (const SbVec4s & v)

Sets this vector to the short integer precision vector v, converting the vector to a unsigned short integer precision vector.

SbVec4us & SbVec4us::setValue (const SbVec4ub & v)

Sets this vector to the unsigned 8-bit integer precision vector v, converting the vector to a unsigned short integer precision vector.

SbVec4us & SbVec4us::setValue (const SbVec4ui32 & v)

Sets this vector to the unsigned 32-bit integer precision vector v, converting the vector to a unsigned short integer precision vector.

const unsigned short * SbVec4us::getValue (void) const [inline]

Returns a pointer to an array of four unsigned short integers containing the x, y, z and w coordinates of the vector.

See also:

setValue()
