Unigine::hvec4 Class

Header:#include <UnigineMathLib.h>

This class represents a vector of 4 half (16-bit float) components.

hvec4 Class

Members


hvec4()

Default constructor. Produces a zero vector.

hvec4(const hvec4 & v)

Constructor. Initializes the vector by copying a given source vector.

Arguments

  • const hvec4 & v - Source vector.

hvec4(half x, half y, half z, half w)

Constructor. Initializes the vector using given half values.

Arguments

  • half x - X component of the vector.
  • half y - Y component of the vector.
  • half z - Z component of the vector.
  • half w - W component of the vector.

Examples

Source code (UnigineScript)
hvec4(2.0, 3.0, 1.0, 4.0);
/*
Creates a vector (2.0, 3.0, 1.0, 4.0)
*/

hvec4(half v)

Constructor. Initializes the vector using given half value.

Arguments

  • half v - Scalar value.

Examples

Source code (UnigineScript)
hvec4(1.0);
/*
Creates a vector (1.0, 1.0, 1.0, 1.0)
*/

hvec4(float v)

Constructor. Initializes the vector using a given scalar value: x=v, y=v, z=v, w=v.

Arguments

  • float v - Scalar value.

hvec4(const vec4 & v)

Constructor. Initializes the vector using a given vec4 source vector.

Arguments

  • const vec4 & v - Source vector.

hvec4(const dvec4 & v)

Constructor. Initializes the vector using a given dvec4 source vector.

Arguments

  • const dvec4 & v - Source vector.

const half * operator const Unigine::Math::half *()

Performs type conversion to const half *.

const void * operator const void *()

Performs type conversion to const void *.

half * operator Unigine::Math::half *()

Performs type conversion to half *.

void * operator void *()

Performs type conversion to void *.

hvec4 & operator=(const hvec4 & v)

Performs vector assignment. Destination vector = Source vector.

Arguments

  • const hvec4 & v - Source vector.

Return value

Result.

half & operator[](int i)

Performs array access to the vector item reference by using given item index.

Arguments

  • int i - Vector item index.

Return value

Vector item reference.

half operator[](int i)

Performs array access to the vector item by using given item index.

Arguments

  • int i - Vector item index.

Return value

Vector item.

hvec4 ONE

Description

Vector, filled with ones (1).

hvec4 ZERO

Description

Vector, filled with zeros (0).
