SbVec3s

NAME

SbVec3s -

SYNOPSIS

#include <Inventor/SbLinear.h>

Detailed Description

The SbVec3s class is a 3 dimensional vector with short integer coordinates.

This vector class provides storage for a 3 dimensional vector as well as simple integer arithmetic operations.

Be aware that this class is an extension for Coin, and it is not available in the original SGI Open Inventor v2.1 API.

Constructor & Destructor Documentation

SbVec3s::SbVec3s (void)

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

Referenced by operator-().

SbVec3s::SbVec3s (const short v[3])

Constructs an SbVec3s instance with initial values from v.

SbVec3s::SbVec3s (const short x, const short y, const short z)

Constructs an SbVec3s instance with the initial vector endpoint set to <x,y,z>.

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