xyVectors

xyVectors: [XYZProps, XYZProps] | undefined

Cartesian coordinate directions defined by X direction then Y direction.

  • The right side contains two vectors in an array.
  • The first vector gives the x axis direction
    • This is normalized to unit length.
  • The second vector gives the positive y direction in the xy plane.
    • This vector is adjusted to be unit length and perpendicular to the x direction.
