Protected Attributes | |
int8_t | vec [2] |
This vector provides storage for a vector in 2 dimensions as well as simple integer arithmetic operations.
SbVec2b::SbVec2b | ( | void | ) | [inline] |
The default constructor does nothing. The vector coordinates will be uninitialized until you do a setValue().
SbVec2b::SbVec2b | ( | const int8_t | v[2] | ) | [inline] |
Constructs an SbVec2b instance with initial values from v.
SbVec2b::SbVec2b | ( | int8_t | x, | |
int8_t | y | |||
) | [inline] |
Constructs an SbVec2b instance with the initial vector endpoint set to <x,y>.
SbVec2b::SbVec2b | ( | const SbVec2ub & | v | ) | [inline, explicit] |
Constructs an SbVec2b instance with initial values from the unsigned 8-bit vector v.
SbVec2b::SbVec2b | ( | const SbVec2s & | v | ) | [inline, explicit] |
Constructs an SbVec2b instance with initial values from the short integer precision vector v.
SbVec2b::SbVec2b | ( | const SbVec2i32 & | v | ) | [inline, explicit] |
Constructs an SbVec2b instance with initial values from the 32-bit integer precision vector v.
SbVec2b & SbVec2b::setValue | ( | const int8_t | v[2] | ) | [inline] |
SbVec2b & SbVec2b::setValue | ( | int8_t | x, | |
int8_t | y | |||
) | [inline] |
Sets this vector to the unsigned 8-bit integer precision vector v, converting the vector to an 8-bit integer precision vector
Sets this vector to the short integer precision vector v, converting the vector to an 8-bit integer precision vector.
Sets this vector to the 32-bit integer precision vector v, converting the vector to an 8-bit integer precision vector.
const int8_t * SbVec2b::getValue | ( | void | ) | const [inline] |
Returns a pointer to an array of two 8-bit integers containing the x and y coordinates of the vector.
void SbVec2b::getValue | ( | int8_t & | x, | |
int8_t & | y | |||
) | const [inline] |
int8_t & SbVec2b::operator[] | ( | int | i | ) | [inline] |
Index operator. Returns modifiable x or y coordinate of the vector.
const int8_t & SbVec2b::operator[] | ( | int | i | ) | const [inline] |
Index operator. Returns non-modifiable x or y coordinate of the vector.
int32_t SbVec2b::dot | ( | SbVec2b | v | ) | const [inline] |
Calculates and returns the result of taking the dot product of this vector and v.
void SbVec2b::negate | ( | void | ) | [inline] |
Negate the vector (i.e. point it in the opposite direction)
SbVec2b & SbVec2b::operator*= | ( | int | d | ) | [inline] |
Multiply components of vector with scalar value d. Returns reference to self.
SbVec2b & SbVec2b::operator*= | ( | double | d | ) |
Multiply components of vector with scalar value d. Returns reference to self.
SbVec2b & SbVec2b::operator/= | ( | int | d | ) | [inline] |
Divides components of vector with scalar value d. Returns reference to self.
SbVec2b & SbVec2b::operator/= | ( | double | d | ) | [inline] |
Divides components of vector with double precision floating point value d. Returns reference to self.
Adds this vector and vector u. Returns reference to self.
Subtracts vector u from this vector. Returns reference to self.
