Members
dvec2 ( ) #
Default constructor. Produces a zero vector.dvec2 ( const dvec2 & v ) #
Constructor. Initializes the vector by copying a given source vector.Arguments
- const 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
Source code (UnigineScript)
dvec2(2.0, 3.0);
/*
Creates a vector (2.0, 3.0)
*/explicit dvec2 ( double v ) #
Constructor. Initializes the vector using a given scalar value: x=v, y=v.Arguments
- double v - Scalar value.
Examples
Source code (UnigineScript)
dvec2(1.0);
/*
Creates a vector (1.0, 1.0)
*/explicit dvec2 ( const dvec3 & v ) #
