SbVec3us

NAME

SbVec3us -

SYNOPSIS

#include <Inventor/SbVec3us.h>

Detailed Description

The SbVec3us class is a 3 dimensional vector with unsigned short integer coordinates.

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

Constructor & Destructor Documentation

SbVec3us::SbVec3us (void) [inline]

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

SbVec3us::SbVec3us (const unsigned short v[3]) [inline]

Constructs an SbVec3us instance with initial values from v.

SbVec3us::SbVec3us (unsigned short x, unsigned short y, unsigned short x) [inline]

Constructs an SbVec3us instance with the initial vector endpoint set to <x, y, z>.

SbVec3us::SbVec3us (const SbVec3s & v) [inline, explicit]

Constructs an SbVec3us instance with initial values from the short integer precision vector v.

SbVec3us::SbVec3us (const SbVec3ub & v) [inline, explicit]

Constructs an SbVec3us instance with initial values from the unsigned 8-bit vector v.

SbVec3us::SbVec3us (const SbVec3ui32 & v) [inline, explicit]

Constructs an SbVec3us instance with initial values from the unsigned 32-bit integer precision vector v.

Member Function Documentation

SbVec3us & SbVec3us::setValue (const unsigned short v[3]) [inline]

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

SbVec3us & SbVec3us::setValue (const SbVec3s & v)

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

SbVec3us & SbVec3us::setValue (const SbVec3ub & v)

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

SbVec3us & SbVec3us::setValue (const SbVec3ui32 & v)

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

const unsigned short * SbVec3us::getValue (void) const [inline]

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

See also:

setValue()
