Detailed Description

The SbVec4b class is a 4 dimensional vector with 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

SbVec4b::SbVec4b (void) [inline]The default constructor does nothing. The vector coordinates will be uninitialized until a call the setValue().

SbVec4b::SbVec4b (const int8_t v[4]) [inline]Constructs an SbVec4b instance with initial values from v.

SbVec4b::SbVec4b (int8_t x, int8_t y, int8_t z, int8_t w) [inline]Constructs an SbVec4b instance with the initial homogeneous vector set to <x,y,z,w>.

SbVec4b::SbVec4b (const SbVec4ub & v) [inline, explicit]Constructs an SbVec4b instance with initial values from the unsigned 8-bit integer precision vector v.

SbVec4b::SbVec4b (const SbVec4s & v) [inline, explicit]Constructs an SbVec4b instance with initial values from the short integer precision vector v.

SbVec4b::SbVec4b (const SbVec4i32 & v) [inline, explicit]Constructs an SbVec4b instance with initial values from the 32-bit integer precision vector v.

Member Function Documentation
