Unigine.vec2 Struct

This class represents a vector of 2 float components.

vec2 Class

Members


vec2 ( ) #

Default constructor. Produces a zero vector.

vec2 ( vec2 v ) #

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

Arguments

  • vec2 v - Source vector.

vec2 ( float x, float y ) #

Constructor. Initializes the vector using given float values.

Arguments

  • float x - X component of the vector.
  • float y - Y component of the vector.

Examples

Source code (UnigineScript)
vec2(2.0, 3.0);
/*
Creates a vector (2.0, 3.0)
*/

explicit vec2 ( float v ) #

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

Arguments

  • float v - Scalar value.

Examples

Source code (UnigineScript)
vec2(1.0);
/*
Creates a vector (1.0, 1.0)
*/

explicit vec2 ( vec3 v ) #

Constructor. Initializes the vector using a given three-component vec3 source vector: x=v.x, y=v.y.

Arguments

  • vec3 v - Three-component source vector.

explicit vec2 ( vec4 v ) #

Constructor. Initializes the vector using a given four-component vec4 source vector: x=v.x, y=v.y.

Arguments

  • vec4 v - Four-component source vector.

explicit vec2 ( dvec2 v ) #

Constructor. Initializes the vector using a given dvec2 source vector.

Arguments

explicit vec2 ( ivec2 v ) #

Constructor. Initializes the vector using a given ivec2 source vector.

Arguments

explicit vec2 ( float[] v ) #

Constructor. Initializes the vector using a given pointer to the array of float elements: x=v[0], y=v[1].

Arguments

  • float[] v - Pointer to the array of float elements.

float Length ( ) #

Returns the length of the vector.

Return value

Vector length.

float Length2 ( ) #

Returns the squared length of the vector.

Return value

Squared length of the vector.

float Max ( ) #

Compares the vector components and returns the greater one.

Return value

The greater out of the two vector components.

vec2 Normalize ( ) #

Returns normalized vector.

Return value

Normalized vector.

vec2 Operator*= ( float val ) #

Performs scalar multiplication.

Arguments

  • float val - Scalar value.

Return value

Resulting vector.

vec2 Operator*= ( vec2 val ) #

Performs vector multiplication.

Arguments

  • vec2 val - Vector.

Return value

Resulting vector.

vec2 Operator+= ( vec2 val ) #

Performs vector addition.

Arguments

  • vec2 val - Vector.

Return value

Resulting vector.

vec2 Operator- ( ) #

Performs vector negation.

Return value

Resulting vector.

vec2 Operator-= ( vec2 val ) #

Performs vector subtraction.

Arguments

  • vec2 val - Vector.

Return value

Resulting vector.

vec2 operator= ( vec2 val ) #

Performs vector assignment. Destination vector = Source vector.

Arguments

  • vec2 val - Source vector.

Return value

Result.

float 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.
