This class represents a vector of 3 double components.

dvec3 Class

Members


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

  • const dvec2 & v - Two-component source vector.

explicit dvec3 ( const dvec4 & v ) #

Constructor. Initializes the vector using a given four-component dvec4 source vector: x=v.x, y=v.y, z=v.z.

Arguments

  • const dvec4 & v - Four-component source vector.

explicit dvec3 ( const vec3 & v ) #

Constructor. Initializes the vector using a given vec3 source vector.

Arguments

  • const vec3 & v - Source vector.

explicit dvec3 ( const ivec3 & v ) #

Constructor. Initializes the vector using a given ivec3 source vector.

Arguments

  • const ivec3 & v - Source vector.

explicit dvec3 ( const double * v ) #

Constructor. Initializes the vector using a given pointer to the array of double elements: x=v[0], y=v[1], z=v[2].

Arguments

  • const double * v - Pointer to the array of double elements.

dvec3 & operator*= ( double val ) #
