dvec3 ( ) #
Default constructor. Produces a zero vector.dvec3 ( const dvec3 & v ) #
Constructor. Initializes the vector by copying a given source vector.Arguments
- const dvec3 & v - Source vector.
dvec3 ( const dvec2 & v, double z ) #
Constructor. Initializes the vector using given two-component dvec2 source vector and a scalar.Arguments
- const dvec2 & v - Two-component source vector.
- double z - Z component of the vector.
dvec3 ( double x, double y, double z ) #
Constructor. Initializes the vector using given double values.Arguments
- double x - X component of the vector.
- double y - Y component of the vector.
- double z - Z component of the vector.
explicit dvec3 ( double v ) #
Constructor. Initializes the vector using a given scalar value: x=v, y=v, z=v.Arguments
- double v - Scalar value.
explicit dvec3 ( const dvec2 & v ) #
Constructor. Initializes the vector using a given two-component dvec2 source vector: x=v.x, y=v.y, z=0.0f.Arguments
