  • double z - Z component of the vector.

UNIGINE_INLINE dvec3 (double x, double y, double z)

Initialization by scalars.

Arguments

  • double x - X component of the vector.
  • double y - Y component of the vector.
  • double z - Z component of the vector.

explicit UNIGINE_INLINE dvec3 (double v)

Initialization by a scalar: x=v, y=v, z=v.

Arguments

  • double v - The value of the vector.

explicit UNIGINE_INLINE dvec3 (const dvec2 & v)
