dvec2 Class
Members
dvec2 ( ) #
Default constructor. Produces a zero vector.dvec2 ( dvec2 v ) #
Constructor. Initializes the vector by copying a given source vector.Arguments
- dvec2 v - Source vector.
dvec2 ( double x, double y ) #
Constructor. Initializes the vector using given double values.Arguments
- double x - X component of the vector.
- double y - Y component of the vector.
Examples
dvec2(2.0, 3.0);
/*
Creates a vector (2.0, 3.0)
*/
dvec2 ( double v ) #
Constructor. Initializes the vector using a given scalar value: x=v, y=v.Arguments
- double v - Scalar value.
Examples
dvec2(1.0);
/*
Creates a vector (1.0, 1.0)
*/
dvec2 ( dvec3 v ) #
Constructor. Initializes the vector using a given three-component vec3 vector: x=v.x, y=v.y.Arguments
- dvec3 v - Three-component source vector.
dvec2 ( dvec4 v ) #
Constructor. Initializes the vector using a given four-component vec4 source vector: x=v.x, y=v.y.Arguments
- dvec4 v - Four-component source vector.
dvec2 ( vec2 v ) #
Constructor. Initializes the vector using a given vec2 source vector.Arguments
- vec2 v - Source vector.
dvec2 ( ivec2 v ) #
Constructor. Initializes the vector using a given ivec2 source vector.Arguments
- ivec2 v - Source vector.
dvec2 ( double[] v ) #
Constructor. Initializes the vector using a given pointer to the array of double elements: x=v[0], y=v[1].Arguments
- double[] v - Pointer to the array of double elements.
dvec2 Abs ( ) #
Returns the absolute values of the vector components.Return value
Vector with absolute values.dvec2 Normalize ( ) #
Returns normalized vector.Return value
Normalized vector.dvec2 NormalizeValid ( ) #
Normalizes a vector, makes its magnitude equal to 1. When normalized, a vector keeps the same direction but its length is equal to 1. Check for the zero vector is performed: if the argument is a zero vector, then a zero vector is returned.Return value
Normalized vector.dvec2 Operator*= ( double val ) #
Performs scalar multiplication.Arguments
- double val - Scalar value.
Return value
Resulting vector.dvec2 Operator*= ( dvec2 val ) #
Performs vector multiplication.Arguments
- dvec2 val - Vector.
Return value
Resulting vector.dvec2 Operator+= ( dvec2 val ) #
Performs vector addition.Arguments
- dvec2 val - Vector.
Return value
Resulting vector.dvec2 Operator- ( ) #
Performs vector negation.Return value
Resulting vector.dvec2 Operator-= ( dvec2 val ) #
Performs vector subtraction.Arguments
- dvec2 val - Vector.
Return value
Resulting vector.double[] 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.double 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.Last update:
