Constructor & Destructor Documentation

math::vector4::vector4 (   )  [inline]

Create uninitialized vector.

math::vector4::vector4 (  scalar_t  a, scalar_t  b, scalar_t  c, scalar_t  d = 1 )  [inline]

Create vector initialized with 3 (or, optionally, 4) scalar values. Note: If only 3 values are specified - fourth value is initialized to "1".

Member Function Documentation

const scalar_t& math::vector4::operator[] (  int  i  )  const [inline]

operator [] is used to read, () is to write (to preserve const correctness)

scalar_t& math::vector4::operator() (  int  i  )  [inline]

operator () is used to write, [] is to read (to preserve const correctness)

scalar_t& math::vector4::x (   )  [inline]

Shortcut to vector[0]. Included for convenience only.

scalar_t& math::vector4::y (   )  [inline]

Shortcut to vector[1]. Included for convenience only.

scalar_t& math::vector4::z (   )  [inline]

Shortcut to vector[2]. Included for convenience only.

scalar_t& math::vector4::w (   )  [inline]

Shortcut to vector[3]. Included for convenience only.

scalar_t math::vector4::length3 (   )  const [inline]

Euclidean length of the vector (only first 3 elements of the vector are used for calculation).

scalar_t math::vector4::length3squared (   )  const [inline]

Euclidean length of the vector, squared. This is faster to compute than length, and is often sufficient for the task. Only 3 first elements of the vector are used for calculation.

vector4& math::vector4::normalize3 (   )  [inline]

Normalize vector in place. Use first 3 elements of a vector. In result vector[4] will be set to value 1.

vector4 math::vector4::operator+ (  const vector4 &  other  )  [inline]

operator + between two 4-dimentional vectors

vector4& math::vector4::operator+= (  const vector4 &  other  )  [inline]

operator += between two 4-dimentional vectors

vector4 math::vector4::operator- (  const vector4 &  other  )  [inline]

operator - between two 4-dimentional vectors

vector4& math::vector4::operator-= (  const vector4 &  other  )  [inline]

operator -= between two 4-dimentional vectors
