Protected Attributes | |
short | vec [4] |
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.
SbVec4s::SbVec4s | ( | void | ) | [inline] |
The default constructor does nothing. The vector coordinates will be uninitialized until a call the setValue().
SbVec4s::SbVec4s | ( | const short | v[4] | ) | [inline] |
Constructs an SbVec4s instance with initial values from v.
SbVec4s::SbVec4s | ( | short | x, | |
short | y, | |||
short | z, | |||
short | w | |||
) | [inline] |
Constructs an SbVec4s instance with the initial homogeneous vector set to <x,y,z,w>.
SbVec4s::SbVec4s | ( | const SbVec4us & | v | ) | [inline, explicit] |
Constructs an SbVec4s instance with initial values from the unsigned short integer precision vector v.
SbVec4s::SbVec4s | ( | const SbVec4b & | v | ) | [inline, explicit] |
Constructs an SbVec4s instance with initial values from the 8-bit integer precision vector v.
SbVec4s::SbVec4s | ( | const SbVec4i32 & | v | ) | [inline, explicit] |
Constructs an SbVec4s instance with initial values from the 32-bit integer precision vector v.
SbVec4s & SbVec4s::setValue | ( | const short | v[4] | ) | [inline] |
SbVec4s & SbVec4s::setValue | ( | short | x, | |
short | y, | |||
short | z, | |||
short | w | |||
) | [inline] |
Constructs an SbVec4s instance with initial values from the vector v.
Sets this vector to the unsigned short integer precision vector v, converting the vector to a short integer precision vector.
Sets this vector to the 8-bit integer precision vector v, converting the vector to an short integer precision vector.
Sets this vector to the unsigned 32-bit integer precision vector v, converting the vector to an short integer precision vector.
const short * SbVec4s::getValue | ( | void | ) | const [inline] |
Returns a pointer to an array of four short integers containing the x, y, z and w coordinates of the vector.
void SbVec4s::getValue | ( | short & | x, | |
short & | y, | |||
short & | z, | |||
short & | w | |||
) | const [inline] |
Returns the x, y, z and w coordinates of the vector.
short & SbVec4s::operator[] | ( | int | i | ) | [inline] |
Index operator. Returns modifiable x, y, z or w coordinate of the vector.
const short & SbVec4s::operator[] | ( | int | i | ) | const [inline] |
Index operator. Returns non-modifiable x, y, z or w coordinate of the vector.
int32_t SbVec4s::dot | ( | const SbVec4s & | v | ) | const [inline] |
Calculates and returns the result of taking the dot product of this vector and v.
void SbVec4s::negate | ( | void | ) | [inline] |
Negate the vector (i.e. point it in the opposite direction)
SbVec4s & SbVec4s::operator*= | ( | int | d | ) | [inline] |
Multiply components of vector with scalar value d. Returns reference to self.
SbVec4s & SbVec4s::operator*= | ( | double | d | ) |
Multiply components of vector with value d. Returns reference to self.
SbVec4s & SbVec4s::operator/= | ( | int | d | ) | [inline] |
Divides components of vector with scalar value d. Returns reference to self.
SbVec4s & SbVec4s::operator/= | ( | double | d | ) | [inline] |
Divides components of vector with scalar value d. Returns reference to self.
Adds this vector and vector u. Returns reference to self.
Subtracts v from this vector. Returns reference to self.
SbVec4s SbVec4s::operator- | ( | void | ) | const [inline] |
